DZL biomass-fired horizontal type steam boiler

The DZL series third-generation biomass-fired boiler is a water tube boiler composed of three drums. It is independently developed by ZOZEN Boiler and has independent intellectual property rights. The boiler adopts an assembly structure, consisting of two large components, the upper and lower parts. The upper part is the main heating surface, and the lower part is the combustion equipment. Water-cooled walls are arranged around the front of the boiler body, connected to the drum at the top and to the header at the bottom, forming the combustion chamber to absorb furnace radiation heat. In the rear part, convection tube bundles are arranged between the upper and lower drums. After the fuel is burned in the furnace, the high-temperature flue gas exits the furnace and scours the heating surface of the convection tube bundles horizontally and enters the economizer, and finally enters the dust collector and being discharged through the chimney.
In response to the problem of difficult ash removal in traditional biomass boilers, the third generation of DZL biomass boilers has solved this problem through structural design. The ash is directly deposited into the ash hopper between the lower drums, eliminating blind zones for ash accumulation and enabling real-time ash removal.
