Abstract

Abstract: By way of the studies on the coal consumption, the coal mercury contents and the mercury emission correction factors of the combustion and flue gas purification facilities, and also by taking account of the operating proportion of pollution control equipment during the 12th Five-Year Period, the input and output amounts of the total mercury in coal-fired power plants are calculated for the year 2010 and 2015. It is predicted that by 2015 the mercury emissions from the flue gas of coal-fired power plants to the atmosphere will be reduced, while the mercury contained in the solid wastes will increase, and the amount of mercury in the desulfurization waste water will be kept at the same level of year 2010. Therefore, the total mercury emissions will increase. Moreover, the mercury discharged from the flue gas, the desulfurization waste water and the solid wastes will be 42.92 tons, 123.3 tons and 186.6 tons respectively. The mercury control in the future will be focused on solidification and harmless disposal of mercury in the desulfurization waste water and solid wastes.

Key words: coal-fired power plant, mercury emission control, emissions prediction, 12th Five-Year Plan
