Abstract: A nozzle configuration and control methodology adapted to provide a compact means for configuring and operating an industrial gas turbine on either gaseous or liquid fuel while utilizing fuel staging to achieve very low emissions. More specifically, the outer fuel nozzles are used for delivery of a portion of the premix gaseous fuel and all liquid fuel, but not diffusion gaseous fuel. Water injection for emissions control on liquid fuel and atomizing air for the liquid fuel are also supplied entirely by the outer fuel nozzles. The central fuel nozzle is thus used for the supply of both premix gaseous fuel and all diffusion gaseous fuel. The disclosed configuration reduces the number of required fluid passages thus simplifying the endcover structure while enabling fuel staging to achieve very low emissions on gaseous fuel.
