Boilers are essential pieces of machinery in many different industries. They transform energy sources into usable steam power, generate electricity and heat water for industrial processes.
Boilers come in a range of sizes, constructions, tube types and fuel types. By understanding what each part does, it will become simpler to understand how they function and repair them if ever necessary.
Fuel
Boilers utilize various fuels to generate steam, a form of power that can be utilized in many applications. It plays an essential role in heating buildings and homes as well as running turbines at power plants. Know more about lò hơi và thiết bị lò hơi.
The type of fuel used in a boiler and how well it’s delivered determine its performance, as well as how much it costs to run it.
Boilers consist of a furnace to burn fuel, heat exchanger that transfers heat from combustion products to water, and space for steam formation and collection. To maximize efficiency in this system, select the right boiler design, optimize its use, and avoid energy losses.
Combustion chamber
The combustion chamber is an essential element of boilers and other boiler equipment. Here, fuel and air are mixed together before being ignited.
This process generates heat and a build-up of gas pressure, pushing the piston downward. The piston is then connected to a crankshaft which turns the engine.
Boilers use fuels such as gas, oil or coal to generate hot water and steam. There are two primary types of boiler: fire-tube and water-tube.
Another essential part of a boiler is its expansion tank. This protects the boiler against excessive pressure and guarantees its safety. You can get a course about Steam System.
Heat exchanger
The heat exchanger in boilers and other boiler equipment is an essential element of producing hot water and heating for your home. If it malfunctions, your boiler won’t be able to function properly – so you’ll need to find a way to repair or replace it.
Heat exchangers come in several varieties, such as brazed plate and shell and tube. They’re commonly employed to transfer heat from a boiler’s output to an indoor heating system, hot water storage tank or snow melting equipment.
The type of heat exchanger used depends on the application. For instance, if it’s necessary to achieve high flow rates and/or temperatures, shell and tube heat exchangers could be ideal.
Firebox
Boiler’s firebox is where fuel is burned to generate heat. It typically looks like a box-shaped construction with water surrounding it and flue tubes exhausting hot combustion products into the atmosphere.
A steam locomotive’s firebox features grates to hold solid fuel such as wood, coal or coal dust, and an ash pan underneath them to collect hot ashes and embers. These grates may be shaken manually by hand in smaller locomotives or powered grate shakers for larger ones.
A boiler’s firebox also contains flue tubes that exhaust hot combustion products and heat the water surrounding them. These tubes, sometimes referred to as fire tubes, are attached to one wall of the firebox (front wall for a longitudinal boiler or top for vertical boilers) for convenient access.

Expansion tank
An expansion tank is a small container placed above your boiler’s main tank. It provides space for heated water to escape while providing air for pressure regulation within the system.
Expansion tanks are essential, as without them the pressure in your boiler and any pipes connected to it could become excessively high. This could result in a variety of issues.
The expansion tank consists of two sections: one contains water from your boiler and another controlled by a valve. As pressure builds in your boiler, water presses against diaphragm and compresses air on opposite side, relieving pressure in your boiler while pushing back against water until normal pressure has been restored.
