DHL series coal-fired steam boiler Steam Product thermal capacity: 20-75 t/h Working pressure: 1.25-5.4 MPA Outlet temperature: 184-485 ℃ Available fuel: Bituminous coal,biomass Available industries: Power generation, heating, chemical, food, rubber Introduction DHL corner tube boiler is field assembled boiler, it uses a piping system as the frame of the entire boiler, and it bears the full load of the boiler, which makes a non-framework boiler. At the same time, this frame also serves as the down comer of the boiler and upper and lower headers. The boiler drum is an external type drum, the furnace is a fully enclosed membrane wall structure, the convective heat absorbing surface adopts the flag tube structure. The corner tube boiler has the advantages of compact structure, low steel consumption and rapid temperature increase. Technical advantages • Safe water circulation • 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 • 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.
