Document Summary
More efficient combustion, less no2 formation, limestone reacts with sulfur, creating calcium sulfate and reducing sulfur emissions. Coal+ steam+ oxygen, formation of co and h gas, which are burned to run a turbine. Often combined with second system to create steam for a second turbine. However, this doesn"t address environmental effects of coal extraction. (e. g. mountain top method- bad for the area) A more sustainable approach is input control; reducing or eliminating pollutant formation. Using bmps to reduce organic and inorganic substances mobbing to streams and rivers. Banning the use of phosphate detergents- results in algae bloom. Increase development of other energy resources e. g. natural gas, wind, solar, geothermal. Stripping sulfur from coal before combustion; water intensive, switching air pollution for water pollution. Switching to gas-electric hybrid vehicles, i. e. reducing fossil fuel consumption or mass transit systems. One group of pollutants remains highly problematic- greenhouse gasses (infrared radiation is trapped) --- global warming.
