Abstract:
1. A hydrocarbon combustion power plant featuring ultra low emissions and fast starting on demand, such as to meet peak electric power needs, the system comprising in combination: a source of oxygen; a source of hydrocarbon fuel; a de-ionized water reservoir; a gas generator coupled to said source of oxygen, said source of hydrocarbon fuel and said de-ionized water reservoir; said gas generator adapted to combust the oxygen from said source of oxygen with the fuel from said hydrocarbon fuel source in the presence of water from said de-ionized water source to produce high pressure, high temperature products of combustion; said gas generator having a discharge for the products of combustion; an expander downstream from said discharge, said expander adapted to extract energy from the products of combustion and output power; an exhaust downstream from said expander, said exhaust adapted to release at least a portion of the products of combustion into the atmosphere; wherein said source of oxygen is liquid oxygen with a liquid oxygen vaporizer between said source of oxygen and said gas generator, said vaporizer adapted to convert the liquid oxygen from said source of oxygen from a liquid phase to a gaseous phase before delivery of the oxygen to said gas generator; wherein said vaporizer includes a heat exchange fluid adjacent a heat exchange surface in contact with liquid oxygen from said source of oxygen, said vaporizer adapted to extract heat from said heat exchange fluid sufficient to convert the liquid oxygen from a liquid phase to a gaseous phase; wherein said heat exchange fluid is air, said power plant adapted to route the air from said vaporizer after having been cooled into a compressor of a gas turbine power cycle, such that a power output of said gas turbine power cycle is increased; and said gas turbine power cycle including said compressor having an inlet adapted to receive the heat transfer fluid from said vaporizer as at least a portion of air passing into said compressor, said gas turbine power cycle including a combustor adapted to combust a fuel with compressed air from said compressor, at least a portion of the compressed air being heat exchange fluid air from said vaporizer, and said gas turbine power cycle including a turbine driven by combustion products from said combustor, said turbine adapted to output power at a rate at least partially influenced by a temperature of air entering said compressor inlet.
