Overview:
DHL series corner tube chain grate boiler designed by ZG Boiler is mainly based on the introduced GEF technology and technical researches on the corner tube boiler products. For adapting to chain grate boiler technology developing and boiler market demand, our company innovated the high efficiency, low emission and large capacity chain grate corner tube hot water boiler.

Applications:
DHL corner tube hot water boiler can be used as source host for central heating in city and industrial and mining enterprises, a set of boiler can heat 30000-40000m2 building areas; it can also meet the hot water need for industrial productions.

Benefits:
1. Corner tube chain grate boiler adopts two patents from Xi’an Jiaotong University:
1) Flying dust re-combustion equipment based on the high temperature separation
2) Combined uniform flow design technique of corner tube chain grate boiler flag pattern surface
2. Flue duct of the heating surface in the end portion of the furnace totally adopts membrane water wall structure.
3. The cross girder grate is adopted, so it has the features of less operation resistance, better grate cooling effects, lower breakdown rate, less fuel leak.
4. DHL series corner tube chain grate boiler can adjust itself to many kinds of coal.
5. Two times turbulence combustion design technique is adopted.
6. Flying dust high temperature separation plus flying dust inner circulating fluidized re-combustion.
7. Flag pattern convection heating surface combined uniform flow design technique.
8. Sectional supporting wall structure, better insulation ability, no dust leak, environment-friendly.
9.The arches of DHL series corner tube chain grate hot water boiler can be redesigned according to the specification of the coal.
