Simulation on the Emission of SO2 and NOx from Coal-Fired Power Plants using MM5-SMOKE-CMAQ

MM5-SMOKE-CMAQ regional air quality modeling system was used to simulate pollutants emission from coal-fired power plants in North-Eastern North America. The effects of SO₂ and NO_x on air quality producing from coal-fired power plants in the summer of 2001 were analyzed. Simulations show the contributions for air quality of SO₂ and NO_x emission from coal-fired power plants using different scenarios, Some control measures for coal-fired power plants were discussed. The use of existing emission reduction rules and technologies can diminish the contributions of coal-fired power plants for total emission of SO₂ and NO_x. Further controls for the emissions of SO₂ and NO_x from coal-fired power plants are necessary to reduce the adverse environmental effects.
