摘　　要：乙烯装置裂解炉热效率是衡量裂解炉运行的重要参数,其高低直接关系到乙烯装置的生产能耗。介绍了影响裂解炉热效率的因素,并进行了定量分析。阐明了影响裂解炉热效率的核心因素为烟气热损失,同时也对裂解炉炉壁热损失对裂解炉热效率的影响进行了说明。针对中国石油兰州石化公司乙烯装置裂解炉的实际运行情况,提出了降低烟气氧含量及排烟温度的具体措施。The thermo efficiency of cracking furnace in ethylene plant is an important parameter to measure the operation of the furnace,and it directly influences the energy consumption of the ethylene plant. This paper analyzes the factors which affect the thermo efficiency of cracking furnace,carries out quantitative analysis,points out that the core factor affecting the thermo efficiency is flue gas heat loss,and discusses the influence of furnace wall heat loss on the thermo efficiency of furnace. Based on the actual operation of the ethylene plant at Petro China Lanzhou Petrochemical Company,some specific measures are proposed to lower the oxygen content of flue gas and the exhaust gas temperature.
