The coal-fired boiler has high efficiency, strong overload capacity and wide adaptability to coal types.The boiler is mainly composed of upper and lower drums, convection tube bundle, water wall tube, downcomer and header. The upper and lower drums are arranged longitudinally. The combustion equipment adopts chain grate of chain belt type and is driven by stepless speed change device.The boiler body is composed of vertical upper and lower drum and convection tube bundle.Water wall is arranged around the combustion chamber, and the front and rear arches are made of water wall as framework and castable refractory, so the service life of the furnace arch is longer.The left and right sides of the boiler body are full membrane water wall structure, which ensures the safe and efficient operation of the boiler.

Features of coal-fired boilers:

1.It can be used for bituminous coal, anthracite, lignite, etc

2.Advanced threaded pipe structure, high heat transfer coefficient, low heat loss.

3.Advanced control system and reasonable selection can ensure stable operation and save investment cost.

4.The utility model has the advantages of high thermal efficiency, high combustion efficiency, sufficient output and long service life of the boiler.
