Method and apparatus for vaporizing liquid natural gas in a combined cycle power plant
InactiveUS6367258B1Turbine/propulsion engine coolingTurbine/propulsion fuel heatingPower stationProcess engineering
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.

Dual orifice bypass system for dual-fuel gas turbine
InactiveUS6145318AReduce trafficAvoid heat buildupBurner safety arrangementsBurnersCombustorHeat rejection
Compressor discharge air flows through a heat exchanger in heat exchange relation with cooling water and is supplied at reduced temperature in atomizing air and purge modes to combustors in a dual-fuel gas turbine. The heat exchanger has a pair of bypass passages in parallel with a temperature regulating valve controlling flow of water through the heat exchanger in response to the temperature of the compressor discharge air exiting the heat exchanger. Should the flow control valve close in response to low temperature of the compressor discharge air, in the air atomizing mode, the bypass passages with orifices therein provide a minimum protective flow of cooling water to the heat exchanger. In the purge mode where only half the air flow and heat rejection is required in the heat exchanger and the flow control valve closes, a bypass valve in one of the bypass passages closes to enable reduced flow of cooling water through the heat exchanger.

Ultra low emissions fast starting power plant
InactiveUS7827794B1Fast starting low emissionMinimal capital expenseTurbine/propulsion engine coolingGas turbine plantsNuclear engineeringLiquid fuel
The power plant combusts a hydrocarbon fuel with oxygen to produce high temperature high pressure products of combustion. These products of combustion are routed through an expander to generate power. The products of combustion are substantially free of oxides of nitrogen because the oxidizer is oxygen rather than air. To achieve fast starting, oxygen, fuel and water diluent are preferably stored in quantities sufficient to allow the power plant to operate from these stored consumables. The fuel can be a gaseous or liquid fuel. The oxygen is preferably stored as liquid and routed through a vaporizer before combustion in a gas generator along with the hydrocarbon fuel. In one embodiment, the vaporizer gasifies the oxygen by absorption of heat from air before the air is routed into a separate heat engine, such as a gas turbine. The gas turbine thus operates on cooled air and has its power output increased.
