摘要:

介绍了燃煤电厂超低排放气态污染物监测系统的采样系统和分析单元，分析了其各自的优缺点。对稀释抽取式、冷干抽取式和热湿抽取式3种采样方法，以及非分散红外吸收法（NDIR）、非分散紫外吸收法（NDUV）、紫外差分吸收法（DOAS）、紫外荧光法（UVF）和化学发光法（CL）5种分析方法进行对比。结果表明，冷干抽取式+紫外差分法以及稀释抽取式+紫外荧光法+化学发光法可以较好地符合燃煤电厂超低排放监测的要求。

Abstract:

Advantages and shortcomings were analyzed for the sampling and analyzing units used for the monitoring of ultra low emission gaseous pollutants from coal-fired power plant. Three different sampling methods of dilution extraction, cold dry extraction and heat humidity extraction were compared together with five different analyzing methods including NDIR, NDUV, DOAS, UVF and CL. Results showed that cold dry extraction plus DOAS and dilution extraction plus UVF and CL are more suitable for the monitoring of ultra low emission gaseous pollutants from coal-fired power plant.

Key words: Coal-fired power plant Ultra low emission Gaseous pollutants Monitoring technology
