摘　　要：研究辽宁省三个典型城市(辽阳市、盘锦市、大连市)的现有燃煤锅炉污染现状及经过综合整治后的污染情况,改善城市冬季的大气环境。根据三个城市锅炉房的位置,分别采用Gambit软件对其锅炉房分布情况进行建模,并分别采用Fluent软件对PM2.5质量浓度分布进行模拟。结果表明,辽阳市污染情况是最严重的,其次是盘锦市,而作为沿海城市的大连市污染程度较低。分别对三个城市改造前和改造后的可吸入颗粒物浓度分布进行比较分析,改造后较改造前,三个城市的污染状况都得到了改善,PM2.5的质量浓度均降到了0.03mg/m^3以下。城市燃煤锅炉的改造,对提高冬季室外空气质量和减轻雾霾现象有重要的作用。The coal-fired boiler pollution present situation and the polluted situation after the comprehensive improvement are studied in the three typical cities of Liaoning province （Liaoyang city, Panning city, Dalian city）, in order to improve the urban atmospheric environment during the winter months. According to the position of boiler room in the three cities, Gambit software is used respectively to make model for the distribution, and Fluent software is used to simulate the distribution of PM2.5 mass concentration. The results show that the pollution situation of Liaoyang city is the most serious among the three cities, followed by Panjin, and pollution degree is lower in Dalian city as a coastal city. Respectively the distributions of particulate matter concentration are analyzed comparatively before and after transformation among the three cities, after transformation, the polluted situation is improved in the three cities, Transformation of urban coal-fired boiler plays an important role in improving the outdoor air quality and reducing fog haze phenomenon.
