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.

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 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

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.

Sources: Superior Boilers

A boiler is a closed metal container with a heating element. Its purpose is to produce steam or heat water by increasing the temperature inside the chamber so that it is higher than that of the environment. Boilers also increase the pressure so that it is greater than atmospheric.

The combination of a boiler and a superheater is known as a steam generator.

How do boilers work?

The basic principle of operation of the boilers consists of a chamber where combustion occurs with the help of combustion air. Then, through the use of a heat exchanger, the transfer of heat is performed and the water is heated.

Taking that into account, the term “boiler” is a remnant of the past when steam boilers boiled water to generate steam. Modern boilers generally heat water using natural gas, butane, or propane.

This hot water is distributed to each radiator through a network of pipes. This causes heat to be distributed more evenly throughout the room and provides a more homogeneous temperature throughout the building during the winter months.

What is the structure of a boiler?

The actual structure of a boiler will depend on the type; however, in a general way, we can describe the following parts:

Burner: used to burn the fuel.

Home: it houses the burner inside and its where the fuel is burned to generate the hot gases.

Heat exchange tubes: The heat from the gases is transferred to the water as they travel through these tubes. It also generates steam bubbles.

Liquid-vapor separator: it is necessary to separate the drops of liquid water from the hot gases before feeding them to the boiler.

Chimney: it is the escape route of the fumes and combustion gases.

Housing: contains the home and the heat exchange tube system.

Boiler classification

Several characteristics define the type of boiler:

A. Depending on the relative position between the fluid and the flue gases

1. With multiple smoke pipes – Pirotubular.

2. With multiple tubes of water pipes – Acuotubular.

B. Depending on the number of steps:

1. One step of gas travel.

2. Multi-step.

C. Depending on the energy needs of the process:

1. Hot water boilers.

2. Thermal fluid.

Advantages of gas boilers at home

Price: There are boilers with a variety of prices.

Speed, comfort, and space: for home use, the heating process can be quite fast. You can regulate the consumption and temperature using the built-in thermostat. Also, they do not usually take up much space.

Shelf life In general: this type of boiler lasts longer than other heaters.

Cleaning: Natural gas boilers, unlike some of the alternatives, do not pollute, unlike other means of heating that do emit waste.

Commercial boilers have plenty of advantages. They can operate continuously for prolonged periods. In addition to this, they are more efficient than their residential counterparts, which means they are more environmentally friendly. Being more efficient translates into savings that help your bottom line stay in the black. Here some of its benefits:

Commercial boilers save energy with power fractionation

The high cost and continuous increase in fuel prices have forced energy audits and actions. This has lead to improvements and reforms in industrial facilities, aimed at reducing energy costs. For example, most industries with commercial boilers have installed economizers in the gas outlet. Others have optimized steam distribution and consumption networks.

Many companies have committed to the power fractionation technique. It consists of the installation of several smaller boilers, instead of a larger unit.

This technique allows the boilers to always work in their optimal working range. Additionally, it facilitates greater temperature control and a reduction of the space needed for the boiler room, which brings significant savings.

Advantages of annual maintenance of commercial boilers

When carried out, the yearly inspection of industrial boilers verifies that the devices that work inside the installation are safe and suitable for use.

Upon inspection, it can then be determined whether the commercial boiler is burning correctly with the correct operating pressure.

A proper intervention can help identify potential failures or problems that may need immediate attention.

In many countries, annual maintenance is mandatory. Which will keep your installation within the legal parameters in case of an accident; otherwise, your insurance will refuse to pay.

An annual check may be necessary to maintain the manufacturer’s warranty in your commercial boiler

Performing boiler maintenance will ensure that your furnace and the heating system remains safe to use to verify that your boiler works with the correct operating pressure. That means it will only spend the energy or gas it needs, without wasting money and ensuring that its performance is adequate.

Annual maintenance extends the life of the commercial boiler

When performing the combustion analysis, you need to make sure that the boiler does not emit toxic byproducts such as carbon monoxide. Carbon monoxide at high concentrations can cause serious accidents.

The importance of maintaining the boiler in good condition is evident, as should be the importance of hiring qualified boiler maintenance and repair services.

It is a profitable investment

Although it is necessary to make a high investment, industrial biomass boilers and the storage system are more efficient than traditional fuel boilers. The low operating cost compensates for the initial investment.
