Coal Fired Steam Boiler

DZL Coal Fired Steam Boilers

Products Feature:

1.The drum consists of arched tube sheet and sapirally corrugated tube,which makes the shell change from the quasi-rigid into quasi-elastic,so as to prevent the tube sheet from cracking.
2.The ascending calandria are arranged under the drum.With this arrangement,the dead water zone at the bottom of drum is eliminated,and the sludge is difficult to subside on it.As the result,the high-temperature region of drum obtaind better cooling,and the bulge phenomenon at the bottom of boiler  is eliminated effectively.
3.The optimal design of the spirally corrugated tube strengthens the heat transfer,speeds up temperature repidly and enhances the boiler steam rate.
4.It is the retional design of arcfh inside the furnace that improves  combusion condition,enhances the dust falling function,and reduces the pollutant emission of the boiler.
5.With good sealing,the wind box is easily to operate and can provide retionsl wind.Consequently,it reduces the air excess coefficient and increases the bolier thermal efficiency.
6.With compact structure,the smaller boundary dimension then other same volume boilers,it can save the investment of capital construction for boiler room.
