Biomass Steam Boiler

DZL series biomass boiler belongs to package boiler, and adopts single drum, vertical structure and chain grate type, is suitable biomass pellet, wood chip, waste material and coal, and one single fuel or two fuel mixture is approved. For these DZL series steam boiler, we equipped with economizer to improve the thermal efficiency, blower and induced draft fan to form wind/air circulation system, screw slag machine to discharge slag automatically, excepting these, we also equipped various monitor to ensure boiler safety and stable.

 

SZL boiler adopts two drums, and the steam capacity is bigger than DZL boiler, whose steam capacity is available from 4t/h to 20t/h, and fuel is available to shaped solid material. As main heating area of boiler, the water wall adopts membrane water wall structure and shapes arch structure, which structure not only strengthens boiler seal performance, but also increases furnace volume and heating area, at same time, it reinforces the back arch intensity. During the whole burning system, the flue gas goes through furnace, combustion chamber, convection bank, economizer into smoke channel on boiler back, and then emissions into the atmosphere after dust collector, induced draft fan, chimney, ensuring the quality of the flue gas to meet national environment requirement. Secondary air is set on font wall and controlled by valve in order to make biomass fuel burning fully, and the feeding hole material is used high quality to meet biomass fuel requirement.
