摘　　要：当环境温度变化或燃气轮机进气加热时,燃气轮机逻辑中沃伯指数公式计算值保持不变,不能实时反映燃气轮机的燃烧工况。通过分析燃气轮机DLN2.0+燃烧系统的天然气校正沃伯指数公式,提出压气机进气温度对校正沃伯指数更合理的修改公式。此新公式能全面正确反映环境温度变化或进气加热时的沃伯指数变化,对现场实际运行和燃气轮机系统优化设计也有帮助。When the ambient temperature changes or the gas turbine inlet is heated,the calculated value of Wobbe index formula in gas turbine logic will remain unchanged,which can not reflect the combustion condition of gas turbine in real time.By analyzing the natural gas modified Wobbe index formula of gas turbine DLN2.0+combustion system,the compressor inlet temperature is proposed the new formula can correctly reflect the change of ambient temperature or the change of Wobbe index when the inlet air is heated.It is also helpful for the operation and the optimization design of gas turbine system.
