The coal-fired boiler has high efficiency, strong overload capacity and wide adaptability of coal. The boiler is mainly composed of upper and lower drum, convection tube bundle, water wall pipe, downcomer and header. The upper and lower drum are arranged in vertical way. The combustion equipment adopts chain chain grate and is driven by stepless speed change device. The boiler body is composed of vertical upper and lower drum and convection tube bundle. The combustion chamber is surrounded by water-cooled walls, and the front and rear arches are made of water-cooled walls as the skeleton for pouring refractory castables, and the service life of furnace arch is longer. The left and right sides of the body are full membrane water wall structure, which has good sealing property and small heat loss, so as to ensure the safe and efficient operation of the boiler.
Features of coal-fired boilers:
1. The fuel is widely used and can be used for bituminous coal, anthracite, lignite, etc
2. Advanced threaded smoke 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. High thermal efficiency, high combustion efficiency, sufficient output and long service life of boiler.
