摘　　要：本文以高掺量电石渣替代石灰石生产水泥企业为实例,结合生产记录和能耗统计,通过对烧成系统的热工计算和热工标定两种手段,对工厂现有的电石渣烧成系统和烘干破碎系统进行了分析诊断。分析结果表明,由于补燃炉与水泥生产系统的工艺衔接缺陷及补燃炉系统漏风严重,造成煤耗偏高,本文通过工艺优化分析,提出了新的烘干破碎机取热工艺技术方案并成功实施,可实现节约实物煤5.5 kg/t熟料,年节约原煤4538 t,年创造经济效益227万元。该技术的提出为电石渣生产水泥生产线节能降耗提供了技术手段。In this paper, a cement enterprise using carbide slag as substitute material for limestone was selected to conduct the analysis and diagnosis of burning system and drier-crusher system. Combined with the production records and energy consumption statistics, both the thermaltechnical calculation and thermal technical calibration were performed on the burning system. The results revealed that the high moisture content of carbide slag, the bridging defect between complementary combustion furnace and cement manufacture system and the severe air leakage of Complementary combustion furnace led to a relative high coal consumption. After the optimization of process and technological parameters, the new technological innovation schemewas proposed and successfully implemented. This technology can realize the coal consumption of 5.5 kg per ton clinker, the raw coal reduction of 4538 t per year, and economic benefit of 2. 27 million yuan per year. This optimization process provides a kind of new energy conservation techniques for carbide slag cement production line.
