沸腾炉由于比层燃式手烧炉和喷燃式煤粉炉等炉型的煤耗少、热效率高而被水泥厂的原料烘干普遍使用。但这些炉型都有一个共同的弱点,即:使用寿命不长,一般沸腾炉仅能在1.5~2年左右的正常生产即需停炉维修或更换炉衬。分析其原因,主要在于沸腾炉的某些结构不合理,耐火材料的选择、砌筑方法以及操作失当。 Boiling furnaces are more commonly used in the drying of raw materials of cement plants because of their lower coal consumption and higher thermal efficiency than those of stratified combustion furnaces and pulverized coal combustion furnaces. However, these furnaces have a common weakness, namely: the service life is not long, the general boiling furnace only in the normal production of about 1.5 ~ 2 years that need to shut down furnace repair or replacement of lining. Analysis of the reasons, mainly due to some structure of the boiling furnace unreasonable, the choice of refractory materials, masonry methods and misconduct.
