摘　　要：选取燃烧型煤和原煤的典型链条炉,应用自行设计的固定源烟气颗粒物稀释采样系统,现场测试细颗粒物PM_(2.5)、PM_(10)和金属元素的排放特征。结果表明,型煤燃烧细颗粒物的排放比例高于原煤,型煤燃烧除尘器进口、出口PM_(2.5)质量比原煤燃烧分别增加715%和708%。燃烧型煤时,As和Pb在各粒径段的质量比均比原煤大。同时,由于型煤燃烧可吸入颗粒物的排放比例增加,包含或附着在烟尘上的金属元素排放比例也相应增加。Emission characteristics from the combustion of boiler briquette coal and raw coal were analyzed using a self- designed dilution sampling system that was manufactured to sample the particulate pollutants such as PM（2.5）,PM（10）,and metal elements in flue gas from stationary source. The results showed that the fine particle emission ratio of briquette coal was higher than that of raw coal,and that the mass of PM（2.5）from the inlet and outlet of the dust collector had increase of 715% and 708%,respectively,for briquette coal than raw coal. The mass fractions of As and Pb at different particle size ranges were all higher for briquette coal. At the same time,due to the increase of inhalable particulate matter during the combustion of briquette coal,emission ratio of metals that were contained in or attached to the dust was also increased.
