中文摘要：

为了实现在高铝煤粉燃烧过程中同时产出氧化铝熟料的副产品,将消石灰和高铝煤混合磨细,在马弗炉中高温煅烧,在燃烧过程中煤灰质和氧化钙直接反应,使得氧化铝熟料的煅烧在煤粉燃烧过程中一次完成。实验结果表明：消石灰质量分数最佳范围为29.23%～31.54%,最佳的燃烧温度为1200℃,熟料的主要矿物成分是Ca2SiO4、Ca4Al6O12SO4和黄长石相;另外热重分析表明,添加消石灰后,混煤的燃烧特性比纯煤更好。

英文摘要：

For getting alumina clinker by- product, the lime and high-alumina coM were mixed and milled as coal powder mixture, which were calcined at high temperature in muffle furnace. Coal ash and calcium oxide directly reacted and formed alumina clinker during coal powder mixture combustion process. The results shown that the best percentage of lime in coal powder mixture was 29.23 % -- 31.54 %, the best combustion temperature was 1200℃ and the alumina clinker crystal phases was CazSiO4, Ca4Al6O12SO4 and gehlenite. And from the thermo - gravimetry analysis results, the combustion properties of the coal powder mixture was better than pure coal powder.
