Abstract: In this paper, environmental impact of gas turbine power generation equipment is reviewed and emissions sources are discussed. The types of pollutants in simple cycle gas turbine power plants and the associated air quality problems are compiled. Then, airborne pollutants which are generated in the combustion turbines are described and factors affecting emission formation are discussed. Also, the environmental impact of a number of efficiency boosting techniques including inlet air cooling and cogeneration is presented. It is concluded that environmental impact should be taken into account when economics of different efficiency boosting technologies is evaluated. Also, the conflicting issues of emission dependence on temperature need to be addressed in a broader perspective.

Keywords: gas turbines pollution; exhaust emissions; gas turbine efficiency; NO_x emissions; inlet air cooling; cogeneration; nitrogen oxide; air pollution; air quality; environmental impact; efficiency boosting.
