SZL Biomass steam boiler
Biomass steam boiler (also called biomass hot water boiler) is the hot sale SZL Series biomass boiler which adopts chain grate which is suitable for burning the biomass fuel like wood chip, biomass pellet, etc. SZL series biomass boiler is the kind of double drum natural circulation boiler with the whole “O” shaped arrangement and the use of chain grate. The front of biomass steam boiler is the rising flue duct, that is, the furnace, its four walls are covered with membrane wall tube. The rear of biomass steam boiler is arranged convection bank. The economizer is arranged outside the biomass fired boiler.
Similar to coal fired boiler, SZL series biomass boilers also has the characteristics of big heating surface, high thermal efficiency, little fuel leakage, separate air chamber, sufficient burning, variable frequency control and PLC automatic control, etc al. SZL series biomass fired boiler is often used as biomass steam boiler to generate low pressure steam with rated evaporation capacity of 6-35 tons/h and rated pressure of 0.7-2.5 MPa. It also can be used as biomass hot water boiler to produce hot water. The designed thermal efficiency is up to 82%.
