Coal-burning boiler

A coal-fired boiler (or coal-fired boiler) is an industrial boiler that uses coal fuel for boiling. After boiling, steam is often used in industry. Depending on usage needs, the steam source will have the appropriate temperature and pressure. Because the temperature and pressure are often very high, specialized pipes that can withstand high heat and pressure are usually used. The boiler stands out for its ability to create safe, non-flammable energy sources to operate equipment near fire-prohibited areas or power sources.

What is a coal-fired boiler?

Types of coal – fired boilers 

Due to differences in structure and operating principles, coal-fired boilers are divided into two types: chain-grate coal-fired boilers and static-grate coal-fired boilers.

Burner is an important part of all boilers located in the combustion chamber. Burn is the metal part where fuel is placed on the surface to burn and generate heat.

Chain grate coal fired boiler 

Of the two types of coal-fired boilers, the chain grate coal-fired boiler is more commonly used due to its automatic fuel supply and slag discharge structure, simple operation and reduced human resources. Chain grate coal-fired boilers are small and medium capacity boilers.

Structure of chain grate coal-fired boiler: Combination of water pipes with capacity of 6-60 tons/hour and fire pipes with capacity of 1-6 tons/hour

The boiler includes 3 passes, large and long grate most suitable for coal dust.

Outstanding systems equipped in chain grate coal-fired boilers: dust filter system, water spray system, stepless automatic control system with inverter, water heat recovery system, and hot air increase.

Static grate coal-fired boiler

The outstanding feature of the static grate coal-fired boiler is its large working capacity of up to 1-10 tons/hour. This helps the factory save time and reduce working pressure.

The structure of a chain grate coal-fired boiler is similar to a chain grate boiler, it still includes 3 passes, 2 types of water pipes and fire pipes. The recording surface has a large area and a durable bar shape.

The systems of static grate coal-fired boilers are also equipped with the same systems as the above chain grate boiler systems.

Applications of coal-fired boilers (coal-fired boilers)

Each type of coal-burning boiler (boiler) has structures, characteristics, and operating principles suitable for many different industries.

Coal-burning boilers are widely used in industrial plants to provide and conduct heat and steam sources to the machines that need to be used.

Coal-fired boilers are commonly used in industries such as textile, garment, food, soft drinks, beer, seafood, fish sauce, soy sauce, etc.
