Abstract: A first portion of each of a plurality of Qu-type heat pipes is disposed in a hot gas path, and a second portion of each of the plurality of Qu-type heat pipes disposed away from the hot gas path. Also, the first portion of each of the plurality of Qu-type heat pipes extracts heat from the hot gas path and wherein the second portion of each of the plurality of Qu-type heat pipes creates a vapor that exits each second portion of the plurality of Qu-type heat pipes and away from the hot gas path.

Abstract: A power generation system includes a first compressor, a second compressor, a combustor configured to receive compressed air from the second compressor to produce an exhaust stream, a first turbine, and a power turbine. The first turbine is configured to receive the exhaust stream, generate a rotational power from the exhaust stream, output the rotational power to a second compressor, and output the exhaust stream. The system includes a coupling device configured to couple and decouple the first compressor to/from a second turbine, an electrical generator coupled to an output of the power turbine and configured to output electrical power, and a controller configured to cause the coupling device to mechanically decouple the second turbine from the first compressor, and cause the coupling device to direct compressed air from an air storage cavern to an inlet of the second compressor.

Abstract: A method of reducing the concentration of pollutants in a combustion flue gas having a first temperature is provided. The method includes the step of providing an organic Rankine cycle apparatus utilizing a working fluid and including at least one heat exchanger is arranged in thermal communication with the flue gas. The method further includes the step of reducing the temperature of the flue gas to a second temperature less than the first temperature by vaporizing the working fluid within the heat exchanger utilizing thermal energy derived from the flue gas. The method further includes the step of filtering the flue gas through at least one filter disposed downstream of the heat exchanger to remove pollutants from the flue gas. An associated system configured to reduce the concentration of pollutants in the combustion flue gas is also provided.
