中文摘要:
      为降低水泥生产煤耗，同时实现煤矸石固废的高效高价值利用，设计出煤矸石高效利用系统。系统将煤矸石单独粉磨后送入分解炉内燃烧，喂入分解炉内的煤矸石粉量为3 t/h时，煤矸石带入的热量为3.82 kg/t；此时，熟料烧成热耗降低了3.32 kg/t，计算得煤矸石粉的热效率为86.95%，节煤效益为393元/h；去除煤矸石粉加工成本后，可增加经济效益为123元/h，折合单位熟料生产成本降低0.95元/t。
英文摘要:
      To reduce coal consumption in cement production and achieve efficient and high-value utilization of coal gangue solid waste， a coal gangue efficient utilization system is designed. The system separately grinds coal gangue and sends it into the decomposition furnace for combustion. When the coal gangue powder fed into the decomposition furnace is 3 t/h， the heat brought in by the coal gangue is 3.82 kg/t， and the heat consumption of the clinker during firing is decreased by 3.32 kg/t. Thermal efficiency of coal gangue powder is 86.95%， and benefit generated by coal saving is 393 yuan/h. After removing the processing cost of coal gangue powder， the economic benefits can be increased by 123 yuan/h， which is equivalent to a reduction of 0.95 yuan/t in unit clinker production cost.
