紫外烟气分析仪在燃煤电厂超低排放气态污染物监测中的应用
An application of UV gas analyzer on monitoring of ultra low emission gaseous pollutants in coal fired power plants
摘要
Abstract
With ultra-low emission coal-fired power plants to implement the transformation, the environmental protection department proposed a more stringent gas emission standards. For the new emission standards that were applicable to the high concentration of flue gas monitoring technology which has been difficult to accurately measure the concentration of SO2 and NO under conditions of ultra-low emissions. This paper presents an im-proved UV DOAS technique ( DOAS) , which introduces the basic principles of the technology and technology-based gas analyzer DOAS were ultra-low emission monitoring of engineering applications. The results show that, compared with the non-dispersive infrared analyzer, based on the UV DOAS Technique flue gas analy-zer zero drift and span drift is less than ± 1% F. S./week, absolute error is less than 5 mg/m3 which compared with the reference method, for water vapor, dust and other components in the flue gas with a strong anti-inter-ference, especial y suitable for ultra -low emissions of SO2 and NO condition monitoring, providing accurate monitoring method for ultra-low emission of gaseous pol utants monitored.关键词
