Chain grate is the combustion equipment of chain grate boiler. Coal, biomass energy and other fuels complete the combustion process on the chain grate. The principle of chain grate boiler is to drive the chain grate to rotate through the reducer, so that the solid fuel can catch fire from the front and burn out at the tail of the boiler, which can improve the combustion efficiency compared with the fixed grate. After blanking, welding, assembly and other processes, the finished chain grate will be put into trial operation for 72 hours before leaving the factory, so as to ensure the moderate tightness of the grate and the long-term stability of ZOZEN boiler. Chain grate boiler, ZOZEN boiler supply range covers 2-75 tons, the pressure is 1.0-5.4MPa, the fuel is suitable for biomass particles, anthracite, etc.
