ABSTRACT
Pollutant emissions from combustion processes have become of great public concern due to their impact on health and the environment. The past decade has witnessed rapid changes both in the regulations for controlling gas turbine emissions and in the technologies used to meet these regulations. During this period, the consumption of fuel by civil aviation has increased to the extent that air transport is now perceived as one of the world’s fastest growing energy-use sectors. At the same time, stationary gas turbines have become rmly established as prime movers in the gas and oil industry, and have acquired new ranges of application in combined cycle plants and in many areas of utility power generation. All these developments have been accompanied by continuous and increasing pressure on the combustion engineer to reduce pollutant emissions from all types of gas turbines.
