Abstract: A combined cycle power plant includes a gas turbine having a primary flow passage, a heat recovery steam generator having a heat exchanger disposed downstream from the primary flow passage, an exhaust stack in fluid communication with the primary flow passage and disposed downstream from the heat recovery steam generator and a reversible turning gear coupled to a rotor shaft of the gas turbine. The reversible turning gear counter rotates the rotor shaft during turning gear counter rotation operation of the gas turbine and reverses flow of combustion exhaust gas from the exhaust stack through the heat exchanger and back into the primary flow passage of the gas turbine, thereby conserving thermal energy stored in the heat recovery steam generator. A method for conserving thermal energy of a combined cycle power plant during counter rotation turning gear operation of the gas turbine is also disclosed.

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.

Abstract: A combined cycle power plant comprises a compressor, a combustion section including a compressor discharge casing which is disposed downstream from the compressor, a turbine disposed downstream from the combustion section and an exhaust duct disposed downstream from the turbine section. The compressor, the compressor discharge casing, the turbine and the exhaust duct define a primary flow passage through the gas turbine. A heat recovery steam generator is in thermal communication with the exhaust duct and in fluid communication with a steam turbine. A blower is in fluid communication with the primary flow passage upstream from the heat recovery steam generator such that the blower draws compressed air from the primary flow passage during turning gear operation of the gas turbine.

Abstract: Systems and methods for mitigation of hot corrosion in steam injected gas turbine. In one embodiment, a steam injection system can provide for automatic injection of steam in a gas turbine for NOx abatement and power augmentation. The system can obtain indications as to whether the steam to be injected meets the requirements of the gas turbine in terms of purity and quality. If the quality or purity is not adequate, steam the injection into the combustor or compressor discharge casing (CDC) is automatically inhibited. The system may also monitor the dynamic pressure oscillations inside the combustor. The system may modulate steam flows modulates to enhance the total steam flow while maintaining the dynamic oscillations within acceptable limits.
