摘　　要：煤燃烧过程中产生的SO3不仅造成了酸性烟雾,而且排放时会形成蓝色或黄色烟羽,增加了烟囱排放的烟羽浊度,破环了景观。近年来,火电厂烟囱常见的蓝烟/黄烟现象给周边大气环境带来一定的影响。针对部分燃煤电厂在脱硫、脱硝装置投运后,出现蓝烟/黄烟现象进行了研究,并提出了可供选择的控制对策和建议。The emission of the flue gas SO3 generated in the process of coal combustion not only resulted in the emission of acid fumes,and will form a blue or yellow plume,increasing the turbidity plume emissions from chimney,but also destroying the landscape.Past years,thermal power chimney common emerge blue smoke and yellow smoke phenomenon has bring some impact on around environment.Part of the coal-fired power plants put into operation of WFGD and SNCR denitrification equipments,the emergence of blue smoke / yellow smoke are studied and analyzed,and alternative control strategies and recommendations are put forward.
