摘要： A system for vaporizing liquefied natural gas (LNG) utilizes the residual cooling capacity of LNG to condense the working fluid of a power producing work producing cycle and chills liquids that are used in a direct-contact heat transfer system to cool air. The cold air is used to supply air to a combustion gas turbine operating in conjunction with a combined cycle power plant. Power is produced from both the work producing cycle and the combined cycle power plant and the chilling of the intake air to the gas turbine increases the output capacity of the combined cycle power plant.

摘要： A method and apparatus for increasing the efficiency of a combined cycle generation plant by assisting the vaporization of cold liquid including liquefied natural gas (“LNG”) or liquefied petroleum gas (LPG) in a combined cycle power plant. Cold liquid vaporization is assisted by circulating a warm heat transfer fluid to transfer heat to a LNG/LPG vaporizer. The heat transfer fluid is chilled by LNG/LPG cold liquid vaporization and warmed by heat from a gas turbine. The heat transfer fluid absorbs heat from the air intake of a gas turbine and from a secondary heat transfer fluid circulating in a combined cycle power plant. Chilling the gas turbine air intake densifies the air and increases the gas turbine output. Chilling the steam condenser cooling water increases steam turbine output. The effects of chill recovery is higher output and better efficiency of the combined cycle plant.

摘要： A two stage expansion and single stage combustor compressed air energy storage cycle that employs a heat exchanger to raise the temperature of the compressed air before it enters a high pressure expander. A combustor heats the exhaust from the high pressure expander and creates a working gas to drive a low pressure expander. The exhaust from the low pressure expander is supplied to the heat exchanger to raise the temperature of the compressed incoming air. A portion of the exhaust of the high pressure expander is cooled and employed in a cooling circuit within the low pressure expander. A starter valve in the compressed air input circuit finely tunes the incoming air during startup. The startup air flow is heated by an auxiliary duct burner until the low pressure turbine exhaust reaches operating temperature and is sufficient to heat the incoming air under normal operating conditions.

摘要： A turbojet engine has a capability for propelling an air-borne vehicle over an extremely wide range of operating speeds. A vehicle can be propelled from take-off conditions through speeds in excess of Mach 5. The engine is equipped with a cooling fluid injection system which cools intake air at high operating speeds. Cooling of intake air permits continued turbojet engine operation at speeds which produce stagnation air inlet temperature in excess of those which critical compressor components can tolerate. The inlet air entering the compressor is pre-cooled with injected fluid so that its temperature is reduced below the critical operating temperature limits of the critical compressor components.

摘要： An apparatus for supplying high pressure atomizing and purging fluid to the fuel system of a gas turbine engine. The apparatus is comprised of a turbocompressor, multiple flow conduits and associated valves and controls. Alternative versions of the fundamental apparatus may include heat exchangers for heating and cooling the atomizing and purging fluid within the apparatus. The apparatus works with all types of gas turbine engine cycles well known to one skilled in the art. The apparatus includes a first conduit for extracting a small percentage of the fluid compressed by the turbine engine compressor, and the first conduit is further divided into second and third conduits for supplying portions of the small percentage of compressed fluid to the turbocompressor compressor and turbine. The portion of the fluid flowed to the turbocompressor compressor is compressed and then flowed to the turbine engine fuel system at a location that enhances atomization of the fuel or purges the fuel from the fuel system nozzle after shut-off. The fluid discharged from the turbocompressor turbine is flowed back to the turbine engine to offset engine efficiency losses. The turbocompressor may be configured in any number of mechanical configurations, familiar to one skilled in the art of turbomachinery.

摘要： The power output of a gas turbine is increased by vaporizing a liquid coolant fuel at the inlet of the air compressor, which cools the air and increases the mass throughput of the compressor. The method preferably is used in a gas turbine-driven power generation system for increased power output and particularly during periods of high ambient temperatures or at a high site elevation. The liquid coolant fuel also can be introduced simultaneously into the gas turbine combustor to supplement the normal combustor fuel.

摘要： The air inlet to the compressor of a gas turbine is supplied with liquid nitrogen for cooling the ambient inlet air. The heated nitrogen converts to gaseous nitrogen and is supplied to either the combustor to lower the flame temperature and hence reduce NO.sub.x formations within the combustor or the turbine section to increase mass flow and hence increase power output, or both. Liquid nitrogen is also supplied in heat exchange relation with the cooling system of a generator driven by the turbine section. The operating temperature of the generator is thus lowered, thereby increasing its capacity and power. The nitrogen from the heat exchanger of the generator cooling system converts to gaseous nitrogen and is supplied to the combustor for lowered NO.sub.x emissions or to the turbine for improved mass flow, or both.

摘要： An intercooled gas turbine driven powerplant employing a high pressure two-pass heat exchanger down stream of the final stage of compression is disclosed herein. The flow of hot, highly compressed air is cooled in the first pass of the high pressure heat exchanger by a counter current in-tube flow of either water alone, or preferably, of a cold methane/water mixture. The flow of air, thus cooled, is then available, in the second pass of the high pressure heat exchanger, to accept exhaust heat or the low grade heat, usually rejected, that is found in the heated fluid from the intercooler. The cool air is thus preheated, by the return to the cycle of exhaust heat, intercooler heat, and/or low grade heat from the operation of ancillary equipment prior to its entry into the combustor. Additionally, if a methane/water two phase feed is used to cool the first stage of the heat exchanger, the superheated mixture of steam and methane produced by the heat exchanger provides the ingredients to produce a low NO.sub.x fuel for the gas turbine combustor. Thus the first pass of the high pressure heat exchanger cools the high pressure discharge air flow and simultaneously generates the low NO.sub.x fuel gas (or if water alone is used, a quantity of steam for use in any industrial process). The second pass of the high pressure heat exchanger reheats the air flow with the exhaust heat or intercooler heat and simultaneously cools the water (or other heat transfer fluid) and returns that cold fluid to the intercooler or exhaust heat exchanger.
