Abstract:

Three typical domestic coalfired power plants are chosen.Through mercury balance analysis in coal and flue gas，mercury pollution extend of power plants are understood, and the mercury removal ability of existing denitrification equipment,bag filter, electrostatic precipitator and wet desulfurization equipment are evaluated,which provides a theoretical basis for developing corresponding control measures of mercury pollution.

Key words:

coalfired power plant, mercury removal, pollutant control device, mercury balance
