Our 4 ton wood chip steam boiler is szl series biomass boiler. It can produce 4 ton steam with a certain temperature an pressure per hour, which could used for central heating, greenhouse, poultry house, paper mill, sugar mill, etc.
Our szl series chain grate boiler design is suitable for applications to produce low pressure steam(4-30 t/h, 306-2300 bhp) or hot water(7-18 mw, 700-1800 bhp). The boiler combines the best technologies of biomass combustion and the latest advanced combustion control technologies. SZL wood chips biomass fired water tube boiler is designed as dual drum, the drums are horizontal and lengthways arranged, mounted with traveling grate, natural circulation and water tube. The chain grate type boiler permits a wide range of biomass fuels with high ash contents to be combusted in an efficient manner with the added advantage of automatic de-ashing. Boiler is consisted on two major parts, the upper main body and lower grate part. The Upper main body part including two drums, water tubes, steel structure and packing sheet, all of which will be mounted in workshop.
For most boiler users, extremely low fuel cost is the main attraction of burning wood chips, and other biomass fuels such as palm shell, bagasse, sawdust and bark.
