DHL Series Coal-fired Steam Boiler

Safe water circulation
1.The boiler adopts a unique water circulation structure; the drum is not heated and the heated water flows in one direction. In the event of power cut, the water does not vaporize in water system and the water circulation is safe and reliable.

Anti-seismic Structure
1.Corner tube boiler adopts non-framework structure, its body weight is supported by membrane wall and down comer, and all membrane walls are welded into one whole piece with good anti-seismicity.

Complete sealed structure
1.The boiler proper is surrounded by welded membrane wall, and the steel structure is completely sealed to prevent air leakage. The upper part of the boiler can be separately transported according to the size of the railway transportation limit. The excess air coefficient at the boiler tail is less than 1.2, which not only reduces the heat loss of the exhaust smoke and power consumption of the induced draft fan, but also greatly reduces the environmental pollution of the boiler house.
