摘　　要：海拔高度>2200m的某公司水泥生产线已投产多年,水泥生产能耗和废气排放难以满足日益严格的国家标准要求。经现场节能诊断,对烧成窑尾预热器及废气系统、烧成窑中及三次风管、烧成窑头及篦冷机等实施了节能技术改造,2018年7月完成了改造验收。改造后,烧成热耗降低438.9kJ/kg熟料,熟料电耗降低6.1kW·h/t熟料。投产一年多来,系统运行稳定,达到了预期技改目标。A certain plant located at an altitude of more than 2200m had been put into operation for many years,the energy consumption and emissions could not meet the increasingly stringent national standard.After diagnosis on site,the energy-saving transformations were implemented including the preheater,calciner,exhaust gas treating system,kiln and tertiary air duct,cooler,etc.The upgrade project was completed and accepted in July,2018.After the transformation,the clinker heat consumption was reduced by 438.9kJ/kg.cl,and the power consumption of the clinker was reduced by 6.1kW·h/t.cl.Since it was put into production for more than one year,the system has been operating stably and has reached the expected technical transformation target.
