摘　　要：纯低温双压余热发电可高效回收水泥线低温余热,而水泥线生产规模和工艺流程不同,造成不同水泥生产线产生的废气参数差别较大,对确定双压余热锅炉的蒸汽参数和发电量造成很大困难。针对干法水泥线余热发电中窑头冷却机热量平衡和热效率计算,基于水泥窑系统能量分析,建立了低温余热发电系统中窑头冷却机热量收支平衡方程,并给出了新型干法水泥余热发电系统的冷却机热效率计算方法。The pure low-temperature dual-pressure waste heat power generation system can recover low-tem-perature waste heat emitting from cement production lines efficiently.However,different production scale and process flow of cement production lines result in great difference in parameters of exhaust gas,which causes great difficulty in accurately determining steam parameters of dual-pressure waste heat boiler and power gen-eration capacity.To calculate the heat balance and thermal efficiency of kiln front coolers of waste heat power generation systems in dry-type cement production lines,based on the energy analysis of cement kiln systems,the heat balance equations reflecting heat income and expenditure of kiln front coolers in low-temperature waste heat power generation systems are offered,and the methods of calculating the thermal efficiency of cool-ers of new dry-type cement waste heat power generation system are given also.
