Thermal performance of calciner

There are two types of suspension preheaters: cyclone preheater and vertical cylinder preheater.In the preheater, due to the contact surface between the raw material and the gas.Large volume and good heat exchange, so the thermal efficiency of the system is much higher than other kiln types.M14 SERIES UNIVERSAL CYLINDRICAL GRINDING MACHINE The exhaust gas discharged from the main combustion zone enters the four-stage or five-stage cyclone after complete combustion in the subsequent combustion zone. The preheated raw meal enters the fuel decomposition and combustion zone of the D-D furnace from the three-stage or four-stage cyclone, and enters the kiln through the five-stage cyclone after preheating and decomposition.M13 SERIES CYLINDRICAL GRINDING MACHINE The D-D furnace throat directly connected to the kiln tail is a device for adjusting balance, which can balance the combustion gas volume of the rotary kiln and the high-temperature air passing through the tertiary air duct. At the same time, since the raw meal fed to the D-D furnace forms a eruption layer in the
