Brand Name: BZ
Model Number: DZL
Place of Origin: Hebei, China (Mainland)
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.
Product feature
1. Low coal consumption and High thermal efficiency;
2. Reasonable water cycling, large water capacity and spacious steam volume;
3. Equipped with light chain belt assembly grate, blowing machine and draught fan.
4. High automation, mechanical adjustment of water supply, high and low water level alarm;
5. Low water and blowers interlocking protection;
6. Mechanical operation of boiler coaling, slag discharging;
7. Simple operation and quick installation.
