Corner Tube Coal Fired Steam Boile

The features of the structure and technology of DHL series corner tube chain grate boilers:1. It adopts two patents from Xian Jiaotong University:1) Flying dust re-combustion equipment based on the high temperature separation2) Combined uniform flow design technique of corner tubes boiler flag pattern surface2. Flue duct of the heating surface in the end protion of the furnace totally adopts membrane water wall structure.3. The crossgrider 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-class professional manufacture.4. It can adjust itself to many kinds of coal.5. Two times turbulence combustion design technique is adopted.6. Flying dust hgih temperature separation plus flying fust inner circulating fluidized re-combustio.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 this series boilers can be redesigned according to the specification of the coal.
