摘要： A process for retrofitting an electric power plant that uses two 60 Hertz large frame heavy duty industrial gas turbine engines to drive electric generators and produce electricity, where each of the two industrial engines can produce up to 350 MW of output power. The process replaces the two 350 MW industrial engines with one twin spool industrial gas turbine engine that is capable of producing at least 700 MW of output power. Thus, two prior art industrial engines can be replaced with one industrial engine that can produce power equal to the two prior art industrial engines.

摘要： A process for retrofitting an industrial gas turbine engine of a power plant where an old industrial engine with a high spool has a new low spool with a low pressure turbine that drives a low pressure compressor using exhaust gas from the high pressure turbine, and where the new low pressure compressor delivers compressed air through a new compressed air line to the high pressure compressor through a new inlet added to the high pressure compressor. The old electric generator is replaced with a new generator having around twice the electrical power production. One or more stages of vanes and blades are removed from the high pressure compressor to optimally match a pressure ratio split. Closed loop cooling of one or more new stages of vanes and blades in the high pressure turbine is added and the spent cooling air is discharged into the combustor.

摘要： An industrial gas turbine engine in which a compressor includes later stage airfoils that are cooled using a coolant from an external closed loop cooling circuit or from a heat recovery steam generator. Cooling air compressed by a compressor external to the IGT engine can be used for cooling of the main compressor airfoils with a heat exchanger to preheat a fuel used in the combustor. Or, water and steam from a heat recover steam generator can be used to cool the compressor airfoils in which steam can be bled off from the steam generator for cooling and then reintroduced into the HRSG at a downstream stage. Steam is used to cool the rotor blades while water is used to cool the stator vanes.

摘要： A pressure tap probe having a flexible probe tip that is flexible enough to seal a film cooling hole having a roughened surface such as a TBC applied around the hole. The flexible probe tip is flexible enough to deform around the film cooling hole such that an accurate pressure reading can be observed for the film cooling hole. The flexible pressure tap is used to measure the pressure at a plurality of film cooling holes on a turbine airfoil when a pressure and a flow rate of cooling air is passed through the airfoil. A plurality of film cooling holes are measured by using the flexible pressure tap to determine if the cooling passages and film cooling holes are properly sized to provide adequate cooling for the airfoil.

摘要： A micro gas turbine engine in which the turbine rotor blades are formed as an integral bladed rotor with cooling air passages formed within the blades and the rotor disk by an EDM process. an adjacent stator vane includes an air riding seal with an air cushion supplied through the vanes to provide cooling, and where the air cushion is then passed into the turbine blades and rotor disk to provide cooling for the turbine blades.

摘要： A turbine blade with an airfoil wall having a serpentine flow cooling circuit formed within the wall that includes within each channels that flow toward the blade tip of the serpentine a series of impingement holes and impingement chambers such that the cooling air flowing through the channels of the serpentine forms a multiple impingement cooling passages through the channels. Each channel includes a series of slanted ribs that define the impingement chambers, and each slanted rib includes an impingement cooling hole to direct impingement cooling air onto the backside surface of the wall exposed to the hot gas flow. The channel of the serpentine that flows toward the blade root contains no metering holes and is substantially unobstructed to the cooling air flow. The rotation of the blade produces a centrifugal force on the airflow passing through the channels with the metering and impingement holes to aid in the flow towards the blade tip. The return channels are unobstructed in order to minimize the pressure loss on the return channel of the serpentine circuit.
