Abstract: During the 11^th five-year period, the total installed generation capacity in China increased to 962.19 GW of 2010 from 508.41 GW of 2005, of which thermal power increased from 384.13 GW to 706.63 GW. The coal consumption for electricity increased to 1.511 billion tons of 2010 from 1.063 billion tons of 2005. Dust emission amount from thermal power sector in China was 2.184 million tons in 2010, SO₂ emission was 9.844 million tons, and NO_x emission was 9.542 million tons. Research shows that PM₁₀ total emission amount in China was 37.973 million tons, and PM_2.5 total emission amount was 22.784 million tons in 2010. PM_2.5 emission of primary fine particulate from thermal power sector in 2010 was 1.008 million tons, PM_2.5 emission of transformation from SO₂ was 3.50 million tons, PM_2.5 emission of transformation from NO_x was 2.655 million tons and PM_2.5 emission of transformation from SO₃ was 1.073 million tons. All of PM_2.5 emission from thermal power sector accounted for about 36.1%. In order to reduce PM_2.5 emission, some measures are proposed including strengthening operational management of environmental equipments, formulating new economic policies to guide enterprises to reduce emission voluntarily, and installing wet ESP after wet FGD.
