摘　　要：本文介绍了国内工业副产石膏资源特征,通过对氧化铝气态悬浮焙烧炉和回转窑热平衡原理的研究,在能耗、热效率、天燃气消耗量等方面进行对比分析的结果表明,氧化铝气态悬浮焙烧炉相比回转窑用于石膏煅烧具有显著的节能效果,对煅烧工序节能减排具有重要的意义。This paper introduces characteristics of the industrial by-product gypsum resources in China. Though the research on the thermal balance principle of alumina gas suspension calciner(GSC) and rotary kiln, the energy consumption, thermal efficiency and natural gas consumption, etc. are analyzed and compared. The results show that the alumina gas suspension calciner has remarkable energy efficiency compared with rotary kiln for gypsum calcinations, which is of great significance for the energy saving and emission reduction during the calcination process.
