Ours is from 1970 began to study the work of calciner kiln, in 1976 a process of burning oil line built in 1977 poor coal burning industrial test success, in 1978 a burning bituminous coal technology built and put into production. With suspension preheater kiln with a kiln and kiln calciner kiln has become China's future development direction. As anthracite powder ignition point, high combustion speed is slow, so the bottom side of the decomposition of a pre-combustion chamber design, the primary air with pulverized coal through the cyclones of 17 m / s wind speed so large, was swirling motion into the preheating combustion chamber, the preheating chamber and through another set of rotating blades meet incoming secondary air, swirling air in the pre-combustion chamber enables a strong rotation, coal and gas preheating intense stir together, prompting some coal burn rapidly, resulting in the pre-combustion chamber to maintain a steady, "fire", the majority of coal burning in the pre-combustion chamber after entering the calciner continue to burn, the secondary air from the cooling unit, after settling chamber will be fine cooked materials fall down from high temperature centrifugal fan into the combustion chamber, if the pre-combustion chamber stability is too high, there are slagging hazards, such as red and orange flames lies in the timing of cleanup can prevent slagging from three cyclones in preheated raw material from the lower side tilt into the calciner calciner, for the raw material in the furnace can be better dispersed in the bulk material feed inlet air duct below, attracted by the secondary air duct disperse the material . Kiln decomposition technology in China has been successfully tested in the coal, oil and gas have been put into industrial production, kiln decomposition technique to the rapid development in the international arena.
