Zhongding SHL series biomass fuel bulk boiler is a chain grate boiler, and jointly designed by Xi'an Jiaotong University. The boiler inherits the domestic current mature technique of SHL chain grate boiler, gains technological breakthrough on the following five areas: furnace with water-cooling chamber, back-arch structure design, low thermal inertia, sealed membrane water wall structure, and contact side seal of the grate.



1. The furnace and downtake chamber are surrounded by whole-welded membrane water wall, good sealing, low heat loss, clean and hygienic. 

2. Air preheater and economizer are box-type structure when shipping, shorten the installation period, and increase the sealing performance of tail flue. 

3. Adopts crossgirder grate, small resistance, good cooling performance, low failure rate, low coal leakage. 

4. Part of the biomass fine particles are sprayed into the furnace, the fuel combustion under the mixed mode of “layer combustion + suspension combustion”, combustion efficiency is high.
