摘　　要：工业废气发电的综合利用,对在线分析与检测技术的性能要求逐步提高。本项目采用超高稳定可调滤波光谱仪(TFS)技术,研制近乎免维护的高稳定燃气热值在线分析系统(以下简称系统),在“燃气-蒸汽联合循环发电与干熄焦余热发电项目(CCPP-CDQ)”上,已成功稳定运行考核4个月,与在同一发电机组并行运行的进口产品比较,具有明显的技术优势,其测量值最大相对误差为2.37%。新系统除准确检测燃气热值之外,还能检测燃气中各种燃气目标组分的含量,为生产过程的平稳生产及优化控制提供强有力的物质成分信息支持。By using ultra-high stability adjustable filter spectrometer(TFS)technology,a high-stability online gas calorific value analysis system with low maintenance requirements(hereinafter referred to as the system)is developed.The system has been successfully and stably operated for four months in“the Gas-Steam Combined Cycle Power Generation and Dry Quenching Waste Heat Generation Project(CCPP-CDQ)”.Compared with the imported system products operating in parallel in the same generator set,this domestic system has obvious technical advantages.The maximum relative error of the measured value is 2.37%.In addition to accurately detecting the calorific value of the gas,the system can also detect the content of various gas target components in the gas.
