(PDF) Coal Fired Power Plants: Emission Problems and Controlling
In order to run coal-fired power plants effectively, a cost-effective method is to run the plant on a diverse type of fuel, such as conversions to biomass or municipal waste based power plants. The emission level from this type of plants is estimated to be 20% less CO2 than a coal fired unit operating at a same capacity.
