To know which of these boiler types is the most convenient for you, let us see what a boiler is. “A boiler is an enclosed vessel in which a fluid such as water is heated to produce steam or the vaporized form of a liquid. The steam or hot water is then circulated through a piping system to transfer heat for various applications such as heating, power generation, and other processes. Boilers and associated pieces of equipment are efficient heat exchange systems. However, they can be dangerous if not properly maintained and operated”.

There is a wide variety of boilers for a myriad of applications; from heating a room, to drive the turbines of a utility company. Although all of them produce steam and hot water, they have different designs, differ in their operation, and use various types of fuel. As a result, it is convenient to know more about the boiler types available, so that you can decide which one is the most suitable for your application.    

Industrial Boilers

Fire-tube Boiler

Fire-tube steam boilers are cylindrical vessels that hold water that surrounds a set of tubes conducting hot gases produced by a furnace. Consequently, the heat in the tubes transfers to the water surrounding them, producing steam.

The installation and relocation of modern fire-tube steam boilers are possible because they are available as portable packages. Also, they are easy to maintain. Nevertheless, due to the massive amounts of water at high pressure that the boiler holds, it requires safe operating procedures. The users of fire-tube boilers are industrial and commercial facilities whose processes demand lower steam pressures from this type of boilers. 

Water-tube boiler

Water-tube boilers are highly efficient machines that, by their design, produce superheated dry steam at very high pressures. It feeds large amounts of vapor (several million pounds-per-hour), at very high pressures, up to 5,000 PSIG, to industrial processes. A water-tube industrial boiler has a larger size than a fire-tube.

They are the kind of boilers capable of feeding the processes of heavy industry and utility companies. However, the acquisition and installation costs are high. In the case of heavy industries, they are custom made on the installation site, which can be complicated and time-consuming. Furthermore, they are challenging to maintain. Thus, they require highly skilled personnel for operation and maintenance. 

Commercial Boilers

Commercial boilers have different ways to generate heat; firetube, small water tube, and electric resistance. Their ideal users are universities, libraries, office buildings, schools, laundries, hospitals, and other similar facilities,

Among the different boiler types, commercial boilers are some of the most diverse. These units can use propane, natural gas, electricity, or light oil to provide hot water or steam for process requirements or comfort heating. Based on the type of boiler selected and its application, these systems boost fuel efficiency as high as 99%.

A central heating boiler’s size is proportional to the size of the facility. The ideal size for a boiler is one that can cope adequately with the heating needs the coldest season of the year. A typical commercial heating system has four main components: The boiler produces the heat. The pipes, pumps, and valves, distribute the heat. Radiators and convectors, irradiate the heat to the specific room. Finally, there is a control system that regulates everything.

Home Boilers

Condensing Boilers

Condensing boilers typically extract over 90% of the heat from the fuel they burn, making them both cost-effective and energy-efficient. 

Combination Boilers

A combination boiler is a type of condensing boiler. They are highly efficient and compact, making them ideal for smaller homes. They can act as both, a water heater and also a central heating unit. 

System Boilers

A system boiler directly heats a house’s central heating and also produces hot water for the storage cylinder. It is a heat-only boiler. 

Boiler Types by fuel consumption

Another way that boilers can be classified is by the type of fuel that they burn. The most common are:

Coal 

Most industrial coal-fired boilers run on crushed or pulverized coal, which burns more efficiently than large coal clumps.

Gas and Oil

Gas-fired boilers operate using natural gas, most often a mix of methane, ethane, butane, pentane, or propane. Oil-fired boilers burn gasoline, diesel, and other fossil fuels.

Biomass

Biomass boilers burn plant materials like wood chips, wood construction debris, and corn husks.

Boiler Types by Combustion System

All the boilers mentioned before typically fall into one of the following combustion method categories.

Thermic Fluid

Thermic fluid heaters use fossil fuel inside a closed system. The sealed system can lead to greater efficiency, although it is not ideal for specific applications.

Fluidized Bed

It is the most common method used for burning solid fuels in boilers today; fluidized bed technology involves a bubbling hot mixture of water and material particles (like sand) with fuel in suspension. This mix allows for rapid heat transfer and cleaner, more efficient operations.

If you need one of these boiler types, Teems Steam is here to provide solutions for all of your boiler rental, sales, installation, and operation needs.

A commercial water boiler is designed for space heating purposes. As an illustration, it works ideally for universities, libraries, office buildings, schools, laundries, hospitals, and other similar facilities. To choose the right commercial water boiler, you should take into consideration several aspects. Specifically, observe their process, their fuel consumption, their condensation, and their efficiency.

A commercial water boiler can use propane, natural gas, light oil, or non-fueled electricity, to provide hot water or steam for process requirements or comfort heating. So, depending on the boiler selected and its application, they can have fuel efficiency as high as 99%. There are three basic types of commercial water boilers.

Fire-Tube Boilers

Fire-tube steam boilers are cylindrical vessels that hold water that surrounds a set of tubes conducting hot gases produced by a furnace. Consequently, the heat in the tubes transfers to the water surrounding them, producing steam.

Water Tube Boilers

Water-tube boilers have a furnace that burns gas or another type of fuel whose combustion heats water-containing tubes. As a result, the tubes produce steam by transferring the heat received to the water circulating inside them.

Electric Boilers

Electric boilers are simpler because there is no gas combustion involved in the heating process because they use electricity to heat water. Specifically, electric heating elements heat a sealed tube containing water. This type of boiler is the right solution for areas where electricity is not expensive. Nevertheless, it is the least popular one as it usually costs the most to operate.

Condensation of Exhaust Gases

Condensing Boilers

Condensing boilers run at low temperatures, less than 130 degrees. Flue gas condensation occurs because the flue/exhaust gas cools to the point where it can no longer maintain saturation. These units can achieve an exceptionally high level of thermal efficiency of up to 98%.

Non-condensing Boilers

Non-condensing boilers run at above 130 degrees, and even though they will most likely present a low upfront cost to be acquired, operating costs can influence savings in the long run.

Efficiency

High-efficiency boilers can recover the extra heat, also called latent heat. Consequently, that process makes these boilers more efficient to run. High-efficiency boilers lose only about 10% of the heat produced from the fuel gas via the tubes.

Standard efficiency boilers lose about 20% of the heat produced from the fuel gas via the tubes.

Maintenance

Proper maintenance is a financial benefit, as well as a safety requirement. Lack of maintenance can be dangerous. Repairing a boiler requires looking for the source of the problem instead of just an easy fix.

If your boiler is more than 15 years old, you should seriously consider buying a new one. Trying to retrofit a boiler is expensive and inefficient, and it is not worth the risk.

Conclusion

Water commercial boilers are designed for space heating purposes. Among the different types of boilers, commercial boilers are some of the most diverse. They are of three types, Fire-tube, Water-tube, or Electric.

These units can use propane, natural gas, non-fueled electric only, or light oil to provide hot water or steam for process requirements or comfort heating. If you want assistance to choose the right commercial water boiler, ask here.

A steam generator boiler uses a single tube coil instead of many smaller diameter boiler tubes. The generator forces the flow of hot water through the tube to convert it to steam during a single pass through the coil. 

Operation

The water containing coils go around the steam generator. The furnace heats the water, circulating down through the coiled tube. While traveling down, it turns to steam as it heats, and exits the boiler in a concentrated stream at a point at the bottom of the tube.

Advantages

  • It is generally less potent than a full boiler but it is easier to operate.
  • These generators are also smaller, making them more versatile when there is limited space available.
  • They are often used as auxiliary boilers because they start up very quickly, and in applications with very low load factors.
  • These boilers have a compact design, single water tube, and relatively lower water content. Consequently, they can be up and running at full power in a much shorter amount of time than larger boilers. As a result, they are useful in emergency and quick demand situations.
  • They generally cost less than larger boilers. For this reason, they may be more cost-appropriate for applications that do not necessarily require such high levels of steam.
  • They perform well at part loads and respond quickly to changes in loads. As a result, they dramatically increase part load operating efficiency.
  • The fact that they do not have pressure vessels means that in most locations, they do not require a boiler operator. 
  • A steam generator boiler is useful where it can give operational efficiency because it costs around 50% more for the same horsepower output than larger boilers.

An industrial Boiler is a closed pressure vessel that produces high or low-pressure steam or hot water for industrial use. Generally, there are two types of boilers used in industrial applications—Fire-tube and Water-tube boilers.

The use of a fire-tube or water-tube industrial boiler depends on the industrial process for which they are going to generate steam or hot water. 

Fire-tube Industrial Boiler

Fire-tube boilers are a cylindrical vessel in which the flames in a furnace produce hot gases that pass through tubes surrounded by water. Consequently, the heat contained in the tubes transfers to the water, heating it, and producing steam.

A fired-tube industrial boiler is employed in processes that require low pressures, up to 250 PSIG. Furthermore, due to their size limitations, up to 50,000,000 BTU/hr, do not produce large amounts of steam. 

Operation 

The fire-tube boiler holds a firebox where flames produce hot combustion gases. A cooling jacket that contains water surrounds the firebox and connects to the long cylindrical boiler shell. The water surrounds a series of fire-tubes or flues that heat the water, generating saturated (wet) steam. That steam rises to the boiler’s highest point, called steam dome, where it accumulates.

A regulator located in the steam dome controls the exit of the steam. A series of larger flues (tubes) situated at the top of the boiler, conduct the saturated (wet) steam back, turning it into dry or superheated steam. The boiler produces superheated steam and exhaust gases, feeding a steam engine’s cylinders. Those machines turn the energy of the steam into mechanical work. The exhaust gases are recycled to preheat the water that enters the boiler, thus increasing its efficiency.

Maintenance

  • The maintenance and cleaning operations of a fire-tube steam boiler relatively simple. They have easy access to its firesides, allowing the change of the fire tubes without further repair of the boiler.
  • The control systems are less complicated than the ones on water tube boilers.
  • The accessories required by a fire-tube boiler are available at economical prices, due to the relatively low pressures that they have to stand.
  • They are not only easy to operate, but they are also fuel-efficient.

Water-tube Industrial Boiler

A water-tube industrial boiler has a larger size than a fire-tube. It feeds large amounts of steam (several million pounds-per-hour), at very high pressures up to 5,000 PSIG, to industrial processes.

Water-tube boilers are highly efficient machines that, by their design, produce superheated dry steam at very high pressures. They are the kind of boilers capable of feeding the processes of heavy industry and utility companies.

Operation

In general, the water tube boiler design includes several drums. Specifically, the lower water drum and the upper steam drum. They are connected by tubes that form the furnace and convection section. The tubes that make up the furnace walls receive the heat and transfer it to the water contained in them, producing steam. Afterward, the hot water rises and enters the upper steam drum. There, the saturated (wet) steam exits off the top of the drum to feed processes or to produce superheated steam.

Maintenance

  • The larger the amount of steam and pressure produced, the larger the size of the boiler. As a result, they have to be assembled and installed on the site of their operation.
  • The preassembled “packaged” boilers, up to 1,500 PSIG, are easier to maintain than the larger ones.
  • The assembly and installation process of the boilers at the site where they are going to work can be comparatively difficult and time-consuming.
  • The difficulty of the cleaning process makes the maintenance process a complicated task that requires highly skilled personnel.
  • It is not possible to replace the tubes, because there is not a common standard of fabrication.

Conclusion

Fire-tube boilers are widely available in packaged form, allowing smooth relocation and installation. They are also easy to operate, control, and maintain. Nevertheless, due to their design, they are limited in their capacity to produce both–Large amounts of steam and very high pressures.

Water-tube boilers are highly efficient, produce large amounts of steam at very high pressures. The packaged type boilers are easier to maintain than the larger ones. Most water-tube boilers with a pressure capacity beyond 1,500 PSIG have to be custom assembled and installed in their working location. Due to their design and large sizes, they are challenging to maintain.

Here are some pointers that will let you know when it’s time to replace your commercial boiler.

Inefficient combustion

This is the most obvious reason to consider replacing your existing commercial boiler. A boiler that’s not completely combusting its fuel will generate CO2, which can prove lethal to on-site workers if precautions are not taken. This is why we recommend always installing a CO2 detector on every boiler room, no matter how new the equipment actually is.

During servicing, the engineer must check for CO2 leaks, and clean all the dirt that might prevent the gasses to mix optimally inside the boiler. If there’s a dirt buildup the flame will likely appear as yellow, instead of blue.

Leaking commercial boiler

Age can create cracks on the body of your boiler or simply corrode it to the point that there’s a leak. Besides leaking harmful CO2, it can also leak water and create water damage on the boiler room and the adjacent rooms as well.

Strange banging and bubbling noises inside your commercial boiler

There are a few reasons while a boiler might be doing strange noises, here are a few of them.

A blockage within the system can create a pressure build-up which generates all sort of noises within a boiler or the pipes.

A poorly performing water pump can also introduce air bubbles to the system, which makes it work a lot harder.

As soon as you hear an unusual noise contact your maintenance crew. Early detection usually makes a problem repairable. But sitting on it may lead to a catastrophic failure, which may leave your boiler out of commission.

Age and obsolescence

Most boilers are designed to work for 15 to 20 years. If your boiler is beyond this threshold it is probably due for decommissioning and replacing.

Otherwise, the maintenance cost will slowly increase until its more expensive to keep it running than to actually replace it.

Even if it’s working perfectly fine and no repairs have been needed, a 20-year-old boiler is vastly inferior to newer more efficient boiler technology. Upgrading to a newer model could be worth it to save money on daily use, like power or fuel.

Reliability of your commercial boiler

If your boiler is increasing its downtime it’s probably just letting you know that it’s on its last legs. A malfunctioning boiler may make you have to stop your whole operation. Keeping it may eventually cost you more than replacing a boiler that’s increasingly out of commission. Don’t wait for it to fully die on you to start looking into replacing options since that can make your company close its doors for a long period.

Availability of spare parts

If parts are increasingly hard to find, it may be a sign that you are working on an obsolete model. Parts for a boiler can usually be found up to 5 years after the model has been discontinued. After that, you are going to have to Macgyver your way into keeping it working. At that point, it’s better to upgrade your boiler rather than risking a catastrophic failure.

Fire-Tube Steam Boilers

Fire-tube steam boilers are cylindrical vessels that hold water that surrounds a set of tubes conducting hot gases produced by a furnace. Consequently, the heat in the tubes transfers to the water surrounding them, producing steam. 

Advantages of Fire-Tube Steam Boilers

  • Fire-tube steam boilers are widely available as “packaged” systems. Thus, their transportation and relocation are rather easy. 
  • Their installation is rather simple, if previously an adequate foundation and the connections to water, electricity, fuel, and steam systems are in their place by the time of arrival.
  • The maintenance and cleaning operations of a fire-tube steam boiler relatively simple. They have easy access to its firesides, allowing the change of the fire tubes without further repair of the boiler. 
  • The control systems are less complicated than the ones on water tube boilers.
  • The accessories required by a fire-tube boiler are available at economical prices, due to the relatively low pressures that they have to stand.
  • They are not only easy to operate, but they are also fuel-efficient. Their range of operation is between 600,000 BTU/hr to 50,000,000 BTU/hr.
  • They are used for space heating and diversity of industrial operations.

Disadvantages

  • Although fire-tube boilers are smaller in design, they have a larger water volume than similar size water-tube boilers, causing them to take longer to bring up to operating temperature from a cold start. 
  • Generally, this type of steam boilers generates a maximum output of 27,000 kg/h. Most commercial and industrial users that demand a higher output install multiple fire-tube boilers in tandem.
  • Fire-tube boilers can’t work with applications that require high pressure, beyond 250psig.
  • The cause is the large diameter that the cylindrical bodies of fire-tube boilers have.

Water Tube Steam Boilers

Water-tube boilers have a furnace that burns gas or another type of fuel, whose combustion heats water-containing tubes. As a result, the tubes produce steam by transferring the heat received to the water circulating inside them. Next, the resulting vapor reenters the furnace through a superheater to generate extra pressure. In particular, this device heats the saturated steam above the boiling point at very high pressure, turning it into superheated dry steam, which leaves the boiler with pressure high enough to drive large turbines. They are used by industries and utilities that demand high-pressure steam for their processes.

Advantages of Water-Tube Steam Boilers

  • They contain minimal amounts of water; therefore, they have a high capacity to respond to fluctuations in load and heat supply.
  • Their design containing small diameter tubes and steam drum, allows for the toleration of very high steam pressures, up to 160 bar. 
  • Water-tube boilers are highly efficient because they economize fuel by the use of an induced draft that feeds the furnace fire. Also by the recirculation water for preheating purposes, and for their capacity to produce superheat.
  • They can produce high steam pressures, up to 5,000 psi.  

Disadvantages

  • The degree of pressure that they produce limits their availability as preassembled “packaged” boilers, up to 1,500 psi.
  • The assembly and installation process of the boilers at the site where they are going to work can be comparatively difficult and time-consuming.
  • Their cost, including the installation, happens to be higher than fire-tube boilers.
  • The difficulty of the cleaning process makes the maintenance process a complicated task that requires highly skilled personnel.
  • It is not possible to replace the tubes, because there is not a common standard of fabrication.

Conclusion 

Fire-tube boilers are widely available in packaged form, allowing smooth relocation and installation. They are also easy to operate, control, and maintain. However, they take longer to respond to fluctuations in the pressure demand. Their uses are for space heating and diversity of industrial operations that do not require high pressure.

Water-tube boilers are highly efficient, produce very high pressures, and for their low water content, respond fast to fluctuations in demand for steam. The degree of steam pressure limits its availability as ‘packages” because as the pressure generated increases, so does the size of the boiler.

There is a point beyond which they have to be custom assembled and installed in their working location. They have big sizes, are challenging to maintain, and the cost of acquisition and installation is higher than fire-tube boilers.

Water-tube boilers are highly efficient machines that, by their design, produce superheated dry steam at very high pressures. They are the kind of boilers capable of feeding the processes of heavy industry and utility companies

This article contains succinct technical descriptions of the steam production process in water-tube boilers. If you want a summary, go directly to the CONCLUSION section.

Design

steam boilers
Water tubes within the boiler’s furnace.

Water-tube boilers have water-containing tubes heated externally by the fire produced in a furnace that burns gas or another type of fuel. As a result, they produce steam by transferring the heat received to the water circulating inside them. Next, the resulting steam feeds industrial processes downstream. Water-tube boilers hold the pressured steam in the tubes, hence their large size. They have a steam capacity of 4,500 – 12,000 kg /hr, with very high pressure.

Operation

In general, the water tube boiler design includes several drums. Specifically, the lower water drum and the upper steam drum, which are connected by tubes that form the furnace and convection section. The tubes that make up the furnace walls, receive the heat and transfer it to the water contained in them, producing steam. Afterward, the hot water rises and enters into the upper steam drum, where the saturated (wet) steam exits off the top of the drum to feed processes or to produce superheated steam.

Efficiency

Water-tube boilers are highly efficient for various reasons:

  • The steam reenters the furnace through a superheater to generate extra pressure. In particular, this device heats the saturated steam above the boiling point at very high pressure, turning it into superheated dry steam, which leaves the boiler with pressure high enough to drive large turbines.
  • They recirculate the water left at the bottom water drum to pre-heat the feedwater supply.
  • The exhaust gases return to pre-heat the air blown into the furnace, making up an even draft that heats the boiler’s feedwater supply.
  • These systems have a BTU input ranging anywhere from 500,000 to over 20,000,000. As a result, water tube boilers can provide high-speed steam capabilities and fast response to changing demands due to the relatively low water content.

Uses

Industrial water-tube boilers typically produce steam or hot water primarily for industrial applications that require high pressured steam to drive their processes. For instance, the large turbines of utility companies. They are used less frequently for heating applications.

Conclusion.

Water-tube boilers are highly efficient machines that, by their design, produce superheated dry steam at very high pressures. They are the kind of boilers capable of feeding the processes of heavy industry and utility companies. However, the acquisition and installation costs are high. In the case of heavy industries, they are custom made on the installation site, which can be complicated and time-consuming. Furthermore, they are challenging to maintain. Thus, they require highly skilled personnel for operation and maintenance.

Fire-tube steam boilers are a cylindrical vessel in which the flames in a furnace produce hot gases that pass through tubes surrounded by water. Consequently, the heat contained in the tubes transfers to the water, heating it and producing steam.

Fire-tube can be either low or high pressure. Most low-pressure boilers produce hot water for heating purposes, while the high-pressure boilers produce steam for process use.

This article contains technical descriptions. Hence, go directly to the CONCLUSION section at the end of the post if you are interested in a summary.

Design

They have two types of design, wet-back or dry-back. In the first, the boiler has a water-cooled turn around a chamber used to channel the gases from the furnace into the tube banks. Tube removal and cleaning can be more complicated than in the dry-back design.

The dry-back design has a larger and swingable refractory-lined rear door integrated with the vessel. Through this door, combustion gases transfer from the furnace into the tube banks. It requires more refractory maintenance than the wet-back design.

Operation.

The fire-tube steam boiler holds a firebox where flames produce hot combustion gases. A cooling jacket that contains water surrounds the firebox and connects to the long cylindrical boiler shell. The water surrounds a series of fire-tubes or flues that heat the water, generating saturated (wet) steam. That steam rises to the boiler’s highest point, called steam dome, where it accumulates.

A regulator located in the steam dome controls the exit of the steam. A series of larger flues (tubes) situated at the top of the boiler, conduct the saturated (wet) steam back turning it into dry or superheated steam. The boiler produces superheated steam and exhaust gases. The superheated steam, most of the time, feeds a steam engine’s cylinders and rarely feeds a turbine. Those machines turn the energy of the steam into mechanical work. The exhaust gases are recycled to preheat the water that enters the boiler, thus increasing its efficiency.

The fire tubes run through the length of the boiler and make a turn. That run before making the turn is called a pass. Therefore, a three-pass boiler has three sets of tubes, while a four-pass boiler has four. A boiler with more passes has a higher heat extraction rate and is more efficient than one with fewer passes. The fire–tube steam boilers hold pressures to a maximum of 250 psi and 750 horsepower.

Thermal Efficiency

The addition of tubes to the drum containing the water increases the heating surface of the boiler. The higher the heating surface, the more significant the amount of heat that transfers from the hot gases to the water, thus, increasing the thermal efficiency of the boiler. The thermal efficiency is the ratio of the heat transferred from the fuel to the heat absorbed by the water. Steam boilers that have an improved design and high heat transfer rates reach a thermal efficiency of 80% – 85%.

Safety

Every boiler technician must know the basic principles of boiler operation and maintenance because the safe operation of a boiler can prevent accidents. Steam boilers hold large quantities of very hot water under high pressures. When the pressure in the boiler is close to 100 psi, the temperature of the water reaches more than 300 degrees F. If the pressure suddenly drops to zero, without a corresponding drop in temperature, the water instantly turns to steam, increasing its volume enormously. The result of this reaction may be an explosion. Modern fire-tube boilers have built-in safety controls that prevent this type of event from happening. For more information, contact us here.

Conclusion

Fire-tube steam boilers are cylindrical vessels that hold water that surrounds a set of tubes conducting hot gases produced by a furnace. Consequently, the heat in the tubes transfers to the water surrounding them, producing steam.

Modern fire-tube steam boilers are sold as packages that can be installed rather fast and can be relocated elsewhere. They are easy to maintain. Nevertheless, due to the massive amounts of water at high pressure that the boiler holds, they require safe operating procedures.

Industrial and commercial applications whose processes require lower steam pressures demand this type of boilers. If you require information or assistance for buying, renting, installing, and operating Fire-tube steam boilers, contact us here.

If you really want to save on heating, follow these 10 tips. Your hot water boiler will yield more, and your wallet will appreciate it.

1. Verify that the different intakes (gas, water inlet, and outlet, electricity network) are in good condition.

2. Check that the boiler water pressure is correct: around 1.2 bar with a margin of +/- 25%

3. Regulate the working temperature of the boiler for heating: the appropriate temperature is usually 55-60ºC (although on colder days, and depending on the installation, it may be necessary to raise it a little more ).

If it is a boiler that also produces DHW, it also regulates the temperature at which you want hot water to come out of the taps. If it is an instant mixed wall boiler, the temperature should be around 110°F. And if it is a boiler with a built-in accumulator or with an external accumulator, around 130°F.

4. Regulate the idle temperature: it is recommended to be kept around 75°F during the day, and at 65°F during the night.

Install a thermostat to program the boiler

5. It will turn on only when you need it depending on your needs and habits.

6. Make sure you have purged the radiators well and remember to do it at least once a year before winter comes.

7. Install thermostatic valves on the radiators, combined with thermostatic heads, and you will achieve energy savings of 8% to 13%.

8. Do not put clothes or other objects on the radiators. Also, do not place chairs or furniture in front of them, since they make it slow down the heating process.

Make periodic checks of your hot water boiler:

9. With proper maintenance, your boiler will work better and last longer.

10. If your boiler is old, replace it with a condensing boiler. Superlative condensed gas boilers allow you to save up to 30% on gas. Once you have done this, you can enjoy your boiler with peace of mind!

From all the industrial boilers in the market, you want to buy one that meets your needs and runs at pick operational efficiencies for the longest period of time. Accordingly, there are many factors affecting the buying decision that you have to consider. Those key aspects are types of boilers available, price, lifetime efficiency, operational specifications, size, safety, maintenance, fuel, and accessories.

Types of Industrial Boilers

There are three types of industrial boilers, water tube, fire tube, and firebox. They are configurable for use in many types of operations.

Water Tube Boilers

They are the type of industrial boilers where water passes through tubes while the hot combustion gas flows on the other side of the pipes. Water Tube boilers are more expensive and efficient and less dangerous than fire tube boilers. They produce high temperatures and steam pressure.

Fire Tube Boilers

They are the type of industrial boilers where heat and gases of combustion (from the furnace) pass through tubes that are enclosed on water. They have a lower cost than water tube type and require less maintenance. However, they are not capable of producing high heat, pressure, and steam.

Fire Box Boilers

They are a traditional “locomotive” type of boiler. The “firebox” is the space where the heat originates, producing hot gases that pass through the tubes, heating the fluid. It is reliable but limited in its applications.

Price of an Industrial Boiler

A steam boiler is an expensive piece of equipment. Consequently, price is a crucial variable to be considered when buying one. Nevertheless, in the long run, you may spend more money in downtime for repairs, maintenance, and fuel consumption if you buy a lower price boiler.

Lifetime Efficiency

It is crucial to make the buying decision with the lifetime efficiency of the boiler in mind. Hence, It would be best if you did a cost-benefit analysis for the expected useful life of the boiler. Specifically, you should consider: running times, operational costs, maintenance schedule, and costs, and expected lifetime of the machine. Buying the right kind of boiler saves you money and trouble in the long run.

Operational Specifications

The operational specs give you the matching points with the demands of your facility. Therefore, it is essential to know them beforehand. For instance, if your plant demands high temperature and pressure for its production processes, you need a high-performance boiler. Furthermore, they are a vital input in the feasibility study. Some of them are heat output capacity, temperature, thermal efficiency, and maximum pressure.

Size of an Industrial Boiler

It is vital for various reasons. The more steam you need for operating the facility, the larger the boiler size that you require. Consider that the run costs of an oversized boiler are higher compared to the run costs of an undersized one. Nevertheless, the latter may not be able to meet the high-temperature requirements needed by your facility.

Industrial Boilers Require Safety First

Safety is a primary consideration when buying a boiler. Handling the operation of a boiler is a highly technical job that requires well-trained personnel. They must follow the operational procedures in detail, due to the potential hazard of the high temperatures and pressures involved. High-quality boilers take safety first as an original manufacturing specification. Accordingly, you should check the safety track record of the specific brand and model that you want to buy.

Maintenance of Industrial Boilers

It is vital to take into consideration the maintenance schedule of the boiler. Since you want it to be functioning at peak efficiency for the longest time possible. Additionally, low-quality boilers require frequent repairs, which means that they have to be replaced sooner than one of higher quality.

Fuel for Industrial Boilers

Before buying a boiler, the owner has to consider the type of fuel that the boiler uses, evaluating its availability and cost. Boilers use oil, electricity, coal, natural gas, and propane.

Accessories

Many accessories are necessary to complement the operation of the boiler: de-aerators that remove excess oxygen from the water, safety valves, and others.

Conclusion

You are responsible for the operation of a facility that depends on the high efficiency, long-running times, and extended use-life of an industrial boiler. Therefore, it is crucial to make a decision that you are not going to regret later on. Because you don’t want to have your plant shut down for boiler repairs. Or worse, to have part of your personnel suffering injuries for malfunction of the boiler that you selected.

Accordingly, you want to buy the right model and size of the boiler for your plant requirements. Afterward, you should install it correctly and keep it well operated and maintained by highly skilled personnel. Then, you will have your facility operating at optimal levels for a long time. We have that boiler, call us here to have a conversation about it.
