초록

A gas turbine engine (12) including a water injection system (56) for providing a flow of water (60) to only a pilot diffusion combustion zone (20) of a dual-mode combustor (10) and not to a pre-mixed combustion zone (18) of the combustor. The selective reduction of peak flame temperature in the pilot flame zone provides a maximum reduction in the production of oxides of nitrogen with a minimum consumption of water. The pilot fuel fraction of the combustor may be increased prior to the initiation of the pilot water injection flow. The flow rate of the pi...
