CDZL automatic coal biomass fired hot water boiler is automatic chain grate design, it is mainly consists of boiler host, smoke duct, chimney, fueling system, steam & water system, instrument valves, economizer etc. The boiler is easy operated, coal, wood chips, biomass pellet and rice husk are all available. It is widely used for greenhouse heating, staff daily bathing, hotel, winter central heating, slaughter house hot water supplying etc.
1. Arched tube sheet
(1)Make the shell change from the quasi-rigid into quasi-elastic, prevent the tube sheet from cracking;
(2)Reduce the thermal stress of weld;
(3)Simplify the structure and save the boiler room space.
(1)Eliminate dead water zone at the bottom of drum, and the sludge is difficult to subside on it;
(2)The high-temperature region of drum obtains better cooling;
(3)Avoid bulge at the bottom of boiler.
3. Backwater injection
(1)Increase the reliability of water circulation
(2)Avoid the tube explosion.
4. Spirally corrugated tube
(1)Strengthen the heat transfer and speed up temperature rapidly;
(2)Improve the suppleness to prevent the tube sheet from cracking;
(3)Clean groove itself.
