Abstract: During the Eleventh Five-Year Plan period, great achievements of coal-fired power plant air pollution control in China's power industry, which had reached the world advanced level, had been made. Despite more than 10 times growth of thermal power installed capacity during the period, dust emissions remained a slight decrease; sulfur dioxide control made remarkable achievements, having made a decisive contribution to the national energy conservation and emission reduction targets; nitrogen oxide control made preliminary outcomes and flue gas denitrification projects had been in construction. During the Twelfth Five-Year Plan period, the main tasks of air pollution control in power industry will turn to nitrogen oxide control. In the planning, some principles should be considered as follows: source control and end-of-pipe treatment should be combined; key pollutants control and the best availability technologies should be insisted as a guide; key control indexes should be considered at different levels and written into national planning, national environmental protection planning and power industry environmental protection planning. In respect of air pollution control measures, it is necessary to change development mode of power, strengthen technical guidance and basic work, adhere to the technology and management innovation, and improve the management level.
