摘　　要：以Φ2.3×55 m的炭素回转窑作为研究对象,对回转窑内的煅烧过程进行了数值计算。通过多次改变二、三次供风管的长度,得到了相应条件下窑内的温度分布,并进行了比较和分析。结果表明:二、三次供风管的长度对窑内温度场的影响较小,实践中可以采用无管供风措施,以解决供风管道烧损问题。The numerical simulation was conducted on the kiln by taking a Φ2.3×55 m carbon rotary kiln as example.Through changing the air pipe length of the secondary and tertiary air,the temperature field distributions were obtained in different conditions.The result indicates that the air pipe length has insignificant influence on the kiln temperature,so air would be supplied without pipe in practical engineering to solve the burning out of the air pipe.

关 键 词：炭素回转窑 供风管长度 温度场 无管供风
