摘要： A transition piece for use within a gas turbine engine provides a path between the exhaust from one or more pressure-rise combustors and a downstream turbine for the extraction of work from the exhaust flow. The transition piece provides a non-expanding path for the exhaust flow through the transition piece, and directs the flow so as to be effective in driving the turbine when it reaches the end of the transition piece.

摘要： A two-stage pulse detonation system includes a pre-combustor and a geometric resonator connected via a converging-diverging nozzle to the pre-combustor to create a high temperature and high pressure conditions in the resonator in order to create optimal conditions for detonation initiation. A mixture of a fuel and a gas is burned in the pre-combustor and is passed through the nozzle into the geometric resonator, where the burned mixture is detonated. The detonation propagates through the resonator exit nozzle thus generating thrust.

摘要： A method for improving the overall power rating and thermodynamic efficiency of a steam and gas turbine combined cycle plant having a conventional heat recovery steam generator (“HRSG”) as part of the bottoming cycle by cooling the inlet air to the gas turbine (particularly under circumstances when the ambient inlet air temperature to the gas turbine exceeds about 60° F.) using an external chiller subsystem. The preferred method includes the steps of initially heating a multi-component working fluid consisting of higher and lower boiling components (such as ammonia and water) by exposing the working fluid to the gas turbine combustion gases inside the HRSG, evaporating part of the working fluid to generate a vapor fraction enriched in the lower boiling point component, separating the enriched vapor fraction from the multi-component working fluid in a vapor-liquid separator, condensing the vapor into an enriched liquid, subcooling a portion of the enriched liquid, and then cooling the inlet air to the gas turbine through heat exchange with a portion of the subcooled and enriched liquid.

摘要： A low emissions combustor includes a premixer for premixing liquid fuel and compressed air for achieving low NOx emissions without water or steam injection. The premixer includes a centerbody disposed in a shroud defining an annular flow channel extending between an inlet and outlet of the shroud. A plurality of fuel injection orifices are spaced circumferentially around the centerbody with each having an outlet being substantially flush with an outer surface of the centerbody. The fuel injection orifices inject liquid fuel into the flow channel wherein it is atomized by compressed air channeled through the shroud inlet. In a preferred embodiment, the fuel injection orifices are inclined at an acute angle for injection the fuel toward the shroud inlet to increase differential mixing velocity with the compressed air.

摘要： A pulse detonation device contains a pulse detonation combustor which detonates a mixture of oxidizer and fuel. The fuel is supplied through fuel ducts and the fuel flow is controlled by fuel flow control devices. Oxidizer flow is provided through a main inlet portion and a flow control device directs the oxidizer flow to either the combustor or to a bypass duct, or both. The combustor further contains an ignition source. Each of the flow control devices, fuel flow control devices and ignition source are controlled by a control system to optimize performance at different thrust/power settings for the device.
