燃煤电厂低浓度颗粒物测试的空白试验研究
Study on Blank Test of Low-Concentration Particulate Matter Gravimetric Testing for Coal-Fired Power Plants
摘要
Abstract
The flue gas ultra-low emission has been fully implemented in coal-fired power plants.Therefore,it is imperative to further improve the particle testing technology at low concentrations.In this paper,through field measurements,and in consideration of the related provisions in ISO 12141-2002,the study on the blank test of particulate matter testing at low concentrations is carried out for coal-fired power plants.The blank testing and comparison on imported and domestic cartridges indicate that the imported quartz filter cartridge outperforms the domestic one.In addition,the comparison study of blank test between the integrated sampling head and the membrane is also conducted.It is observed that the disassembling operation can increase the fluctuation amplitude of the blank test deviation.Then based on the study results,the onsite testing is performed.At last,the reasonableness and necessity of blank test are discussed for the establishment and revision of the relevant standards.关键词
