摘要： A method of operating a gas turbine engine having a compressor, a combustor between a waste fluid compressor and a power turbine, a counter-rotating compressor turbine installed downstream of the power turbine, and a heat exchanger having two circuits, in which a heated fluid is prepared by burning fuel with combustion air in a mixture with a waste fluid obtained downstream of a compressor turbine that which is cooled, compressed and heated before mixing with combustion air while keeping the temperature of the waste fluid downstream of the compressor turbine constant and removing a partial flow of the waste fluid into the atmosphere before heating the waste fluid prior to supplying the waste fluid for mixing with the combustion air.

摘要： A semi-closed combined cycle power system is provided which can also convert an open combined cycle gas turbine into a non-polluting zero emissions power system. The exhaust is not emitted into the atmosphere as with typical open combined cycles, but rather is routed to a divider. The divider splits the exhaust into either a return duct or a separation duct. The return duct routes a portion of the exhaust back to the compressor. Before reaching the compressor, an oxygen duct adds additional oxygen to the exhaust to form a gas mixture which includes and steam from the exhaust and oxygen from the oxygen duct. This gas mixture has characteristics which mimic those of air, so that the compressor need not be modified to effectively compress the gas mixture.

摘要： A partially-open turbine cycle for use with a modified gas turbine wherein the cycle's working motive fluid replaces the predominant air-derived nitrogen working motive fluid contained in a conventional gas turbine cycle. The working motive fluid comprises a mixture of predominantly carbon dioxide and water vapor in a Mol percent ratio identical to that of the same molecular components Mol percentage as generated from the combustion of the fuel used. The cycle's is susceptible to a 98 percent reduction of fugitive nitrogen oxide and carbon monoxide mass flow emissions as emitted by present art gas turbines on a rated shaft-horsepower basis, and is further susceptible to high simple cycle and cogeneration plant thermal efficiencies at greatly reduced operating pressures.
