Environmental regulation has constricted over the last few decades as the hydrocarbon burning engines produce primarily large amount of nitrous oxides, carbon monoxide, unburned hydrocarbons and sulphur-oxides. For this reason, gas turbine manufacturers are working towards the design of combustion system that reduces the emission of these compounds. Numerous technologic attempts such as water injection combustion, lean pre-mixture combustion, ultra-lean premixed combustion, catalytic combustion, swirl premixed combustion system or the compartment combustion design along with many other concepts have been introduced. This research paper will introduce each combustion process in brief detail and compare the emission data available from each of them and then recommend the one that is suitable for emission controls.
