The effects of combustor inlet conditions and primary zone water injection on gaseous emissions levels of an industrial gas turbine, burning diesel fuel and natural gas, are presented herein. A comparison of reduced-flow combustor rig emissions and engine emissions is made to verify existing inlet condition correlations for thermal oxides of nitrogen, carbon monoxide and unburned hydrocarbons, and to develop new empirical correlations. Engine tests were conducted over a range of water flow rates and loads, and resultant data was used to develop relationships between combustor exit temperature, water injection rate, and gaseous emissions.
