Commercial boilers are essential for providing heat and hot water in various settings such as hotels, hospitals, schools, and office buildings. These boilers are typically larger and more complex than residential boilers, and they are designed to meet the demanding needs of commercial buildings. In this blog post, we will discuss the different types of commercial boiler parts and their functions.
Boiler Part Types & Functions
The burner is the component that is responsible for heating the water in the boiler. It is typically powered by natural gas, propane, or oil and it works by mixing the fuel with air and then igniting it. The burner is controlled by a flame sensor, which ensures that the flame is burning at the correct intensity.
The heat exchanger is another one of the crucial boiler parts that transfer heat from the burner to the water in the boiler. It is typically made of metal, such as steel or copper, and it is designed to withstand the high temperatures and pressures of the heating process.
The control panel is the component that allows the operator to control and monitor the operation of the boiler. It typically includes a thermostat, which sets the desired temperature for the building, and a pressure gauge, which measures the water pressure in the boiler.
Combustion chamber or firebox
This chamber is where the combustion produced by the burner raises the temperature of the heat exchanger by a few hundred degrees. In this chamber, different fuels are burnt at different times. Most boilers’ combustion chambers burn some combination of kerosene, heating oil, and liquid propane. Cast iron is often used for the firebox or combustion chamber because it is durable and can sustain high temperatures and pressures. Materials utilized must be able to withstand temperatures of several hundred degrees for brief periods of time since this is the temperature range reached throughout the process.
The flue is the component that removes the exhaust gases from the boiler. It is typically made of metal and it is located on the top of the boiler. The flue is connected to a chimney, which carries the exhaust gases out of the building.
The water pump is the component that circulates the hot water from the boiler to the rest of the building. It is typically powered by electricity and it is designed to handle the high temperatures and pressures of the heating process. This component ensures that hot water is distributed uniformly throughout the boiler and ultimately reaches all of the taps and showerheads in our homes, workplaces, and other locations where boilers are installed.
The safety valve is a critical component of the boiler that is designed to release pressure if the boiler becomes too hot or too pressurized. This prevents the boiler from exploding, which could cause serious damage to the building and injury to those inside.
The expansion tank is a small tank that is located near the boiler. It is designed to allow the water in the system to expand when it is heated. This prevents the pressure in the system from becoming too high and causing damage to the pipes.
Water Level Gauge
The water level gauge is the component that shows the operator the water level in the boiler. It is typically a glass tube located on the side of the boiler. The operator can check the water level by looking at the gauge and adding water if needed.
Commercial boilers are complex systems that rely on a variety of components to function properly. Each component has a specific role to play, and it is important to understand the function of each part so that the boiler can be properly maintained and operated. If you suspect any issues with your commercial boiler parts, it is important to contact a professional service technician to diagnose and fix the problem.
