摘　　要：利用“能源利用诊断、分析及节能改造”节能模式,对某隧道窑进行了节能改造。首先通过隧道窑热工测试,对隧道窑的热工性能进行综合诊断,寻找隧道窑热效率低的主要因素,同时为节能改造提供基础数据。然后进行干燥和烧成工序的热平衡计算,确定余热回收及利用系统的形式。最后采用三项节能技术,对隧道窑实施改造,节能率达到44%。Tunnel kiln was reformed according to energy-saving mode,which was energy utilization diagnosis and analysis and energy-saving reconstruction.First,thermal performance was diagnosed,and the basic data for energy-saving reconstruction was provided through the test of tunnel kiln.Then the main factors of low thermal efficiency was found.Second the thermal balance was calculated in drying and sintering process,which determined the form of waste heat recovery and utilization system.Finally the reconstruction was implemented by three energy-saving technologies.It caused energy-saving rate reached 44%.
