DHL Series Corner Tube Chain Grate Boiler
Capacity 20-75 t/14-116 MW
Pressure ≤3.82MPa
Two national patents:

It adopts two patents from Xi’an Jiaotong University: Flying ash re-combustion equipment based on the high temperature separation; Combined uniform flow design technique of comer tubes boiler flag pattern surface.

80-83% boiler thermal efficiency:

DHL series corner tube boiler is the second generation high capacity chain grate hot water boiler, its thermal efficiency can reach to 83%.

Lower breakdown rate:

The crossgirder grate is adopted, so it has the features of less operation resistance, better grate cooling effects, lower breakdown rate, less fuel leak. And the grates are made by the first-lass professional manufacture.

No dust leak, environment-friendly:

Adopting light furnace wall structure, insulation performance is good, no dust leak, environment-friendly. At the same time, the whole boiler adopts the secondary wind turbulent combustion design idea and the fly dust high temperature separation plus flying dust inner circulation fluidized re-combustion.
