Calcining the material in the kiln back end of the combustion gas by convection, heat radiation and heat conduction of the integrated hot refractory heating. Calcining the material in the moving process, the surface is subjected to heat flow OBJECTS convection and thermal radiation heating, but also by the radiant heating hot refractory lining; close to the lining of refractory material is heated directly by hot; in accumulation Section they rely on the calcined material in the middle of the thermal conductive heating material itself. Physical rotation of the kiln body shaking due to stop turning, so OBJECTS alternately heated, the material temperature is relatively uniform. To take full advantage of the heat of evaporation, the volatile combustion in the kiln, rotary kiln with a temperature necessary to improve the combustion secondary blast. After the addition of the second blast, 'main solution is injected into the primary air required for combustion of fuel air from escaping volatiles materials required for combustion air is supplied mainly by the second blast. For high volatile calcined petroleum coke, a second blast after full utilization of volatile fuel screw burning heating disabled. Secondary blast device is due to the appropriate location in the kiln in vitro with the kiln with the installation of a centrifugal blower rpm, and then through the loop leads to the kiln blast air supply pipe. Blower motor powered by a kiln slip ring.
