Emission inventory of primary air pollutants from coal-combustion related sources was developed and MM5-CMAQ model was applied to analyze the impacts of coal combustion in each district and each sector on air quality in Beijing. It was found that the contribution of emissions from coal combustion in Beijing was 70% for SO_2, 20%～40% for PM_(10) and 10%～30% for NO, respectively in January 2005. In July, the contribution of coal combustion in Beijing to SO_2 concentration was only 40%～50% . Heating boilers, which accounted for 50%～70% of that from local coal-combustion sources, were the largest contributor in January while coal-fired power plants were the most important in July. Future coal combustion scenario was designed according to the air pollution control plan on air quality improvement of Beijing Olympics and the 11~(th) five-year plan of energy supply and use in Beijing. The improvement of air quality was simulated to analyze the effectiveness of control measures including reducing SO_2, PM, and NO_x emission from power plants, turning off coke production, moving of steel and cement plants, the replacement of small heating boilers, and reduction of residential coal consumption. The results indicated that average SO_2 concentration in January would decrease about 30% , however, the concentrations of NO_x and PM_(10) would decrease less than 15% compared with 2005 base case.
