DHL Corner Tube Chain Grate Steam Boiler

The DHL corner tube chain grate boiler adopts the national patent technology,self supporting membrane water wall structure and other technologies,has the characteristics of high thermal efficiency,low operation cost,long-term trouble-free operation,lightweight,little infrastructure investment,easy transportation.So the boiler is widely used as large energy equipment with steam outputs of 20 t/hr to 116 t/hr.

1.The DHL corner tube chain grate boiler adopts two patents from Xi’an Jiaotong University:Fly ash inner circulating fluidized re-combustion equipment based on the high temperature separation technology,combined uniform flow design technique of corner tube boiler flag pattern convection heating surface.

2. The DHL corner tube chain grate boiler uses the crossgirder grate,it has the features of less operation resistance, better cooling effect,lower breakdown rate and less fuel leak. And the combustion system is manufactured by the first-rated domestic manufacturer.

3. Two times turbulence combustion design technology is adopted.

4.Light grate wall structure,good heat preservation performance,no ash leakage,and excellent working environment.

5.Furnace arch can be designed according to customers’different requirements for types of coal.

6.Gas pass of heating surface around the furnace end all adopt the membrane water wall structure.
