Automatic feeding coal boiler with chain grate stoker auto control boiler

General features of the DZL series hot water boiler: Low pressure, horizontal, industrial, coal fired, fire tube, automatic chain grate steam boiler. The rated evaporation is between700kw to 14000kw.

Product advantage:

1.       Spirally corrugated tube

Function: (1) Heat transfer enhancement; (2) Improve the suppleness to avoid the tube plate cracking; (3) Clean groove itself.

2.       Arched tube plate

Function:  (1) reduce the thermal stress of weld; (2) improve the tube plate suppleness; (3) simplify the structure and save the boiler room space.

3.       Complete protection device

Function: deal with the situation of overpressure, over-temperature, water shortage and flameout.

4.       Up-tube layout

Function: (1) Avoid the bulging on boiler drum; (2) Promote the water cycle (3)clean the sediment in the boiler bottom.

5.       Airfoil flue

Function: Lower the high temperature of tube plate flue gas. And then reduce the thermal load of the boiler bottom.

6.       The return water injector

Function: Increase the reliability of the water circulation and avoid the booster caused by the poor circulation.
