Abstract: A power plant includes a gas turbine including a turbine extraction port that is in fluid communication with a hot gas path of the turbine and an exhaust duct that receives exhaust gas from the turbine outlet. The power plant further includes a first gas cooler having a primary inlet fluidly coupled to the turbine extraction port, a secondary inlet fluidly coupled to a coolant supply system and an outlet in fluid communication with the exhaust duct. The first gas cooler provides a cooled combustion gas to the exhaust duct which mixes with the exhaust gas to provide an exhaust gas mixture to a heat exchanger downstream from the exhaust duct. The power plant further includes a fuel heater in fluid communication with the outlet of the first gas cooler.

Abstract: Methods and systems for imparting corrosion resistance to gas turbine engines are disclosed. Existing and/or supplemental piping is connected to existing compressor section air extraction piping and turbine section cooling air piping to supply water and anti-corrosion agents into areas of the gas turbine engine not ordinarily and/or directly accessible by injection of cleaning agents into the bellmouth of the turbine alone and/or repair methods. An anti-corrosion mixture is selectively supplied as an aqueous solution to the compressor and/or the turbine sections of the gas turbine engine to coat the gas turbine engine components therein with a metal passivation coating which mitigates corrosion in the gas turbine engine.

Abstract: A method and system for transitioning a gas turbine from burning gaseous fuel to liquid fuel and purging the liquid fuel therefrom after transfer back to the gaseous fuel are disclosed herein. The method includes pressurizing a volume of liquid fuel in an accumulator with a first volume of motive gas. A valve is opened in response to low gaseous fuel pressure in the gas turbine to permit the volume of liquid fuel to flow through a conduit to the gas turbine. A volume of flushing medium is pressurized in the accumulator with a second volume of motive gas. The valve is opened to permit at least a portion of the volume of flushing medium to flow through the conduit to flush any of the volume of liquid fuel remaining in the conduit after the gas turbine consumes the volume of liquid fuel.
