摘要： An ejector system and method of operation for combining high and low pressure fluid flow streams is disclosed. A nozzle chamber communicates with a high pressure fluid flow stream and a suction chamber communicates with a low pressure fluid flow stream. The outlet of the nozzle chamber exit into the suction chamber and include multiple nozzles such that the high pressure flow stream exits the nozzle chamber in multiple flow streams having multiple surface areas for interlayer drag between the flows. The low pressure fluid flow stream is entrained by the high pressure fluid flow streams exiting the multiple nozzles to define an intermediate pressure flow stream.

摘要： A method for recovering energy from bleed air from a compressor of a gas turbine is provided. The method includes directing bleed air from a compressor of a gas turbine into a cooling unit. The bleed air is compressed air from the compressor, and the bleed air is not directed into a combustion chamber of the gas turbine. The method also includes cooling the bleed air within the cooling unit. The method further includes expanding the cooled bleed air within a turbo-expander to generate power.

摘要： A system and method to reduce the gas fuel supply pressure requirements of a gas turbine, which results in an increased operability range and a reduction in gas turbine trips. According to the method, the gas turbine is allowed to start and operate at supply pressures determined as a function of ambient conditions and gas turbine compressor pressure ratio. This increases the operability window, and reduces or eliminates the need for gas fuel compressors.
