title: [Mercury emission characteristics from coal-fired power plants based on actual measurement].
abstract: To sample and test mercury emission characteristics in different power plants, six representative coal-fired power plants were selected. And based on the data of mercury emission concentration from actual measurement, mercury removal rate and mercury average emission factor of every plant can be calculated, and mercury emission characteristics about every level capacity can be given, so as to provide support and foundation for the mercury control in China. The mercury emission concentration is about 4.72-14.54 microg/m3, mercury removal rate is about 20.89%-70.63%, and mercury average emission factor is about 14.09-56.08 microg/(kW x h). To compare the mercury emission characteristics with mercury emission characteristics from coal-fired power plants in USA, it is shown that the concentration of mercury emission from coal-fired power plants in China is far higher than those in USA, and the mercury removal rate is much lower than removal rate required by American national standard. To get conclusion that mercury average emission factor can come down with installed capacity and power generation load went up. And the function relation have been provided through comprehensive simulation between mercury average emission factor and installed capacity, generation load, mercury content in coal, the environmental protection equipment running level, and so on.
