摘要： A method of generating electrical power includes expanding a flow of exhaust gas from a combustion process as the exhaust gas passes through a turbo-expander disposed on a turbo-crankshaft. The flow of exhaust gas from the turbo-expander is routed through a first flow path of an exhaust gas heat exchanger. The flow of exhaust gas from the first flow path is compressed as the exhaust gas passes through a turbo-compressor disposed on the turbo-crankshaft. The flow of exhaust gas from the turbo-compressor is routed through a second flow path of the exhaust gas heat exchanger. Heat from the first flow path is transferred to the second flow path to cool the exhaust gas in the first flow path and heat the exhaust gas in the second flow path. Electrical power is generated from a generator disposed on the turbo-crankshaft.

摘要： A cooling system for cooling hot components of a radial or axial gas turbine engine, which includes a recuperator heat exchanger, provides engine cooling without loss of thermal efficiency. Air flow leaving a compressor is split between a recuperator flow path and a bleed flow path. Air in the bleed flow path flows through the hot parts of the engine, thereby cooling the engine and heating the air. The air in the bleed flow path is combined with the output flow from a combustor and directed into a turbine inlet. A reduction of air flow in the recuperator flow path increases the thermal effectiveness of the recuperator heat exchanger by increasing a ratio of hot and cold flows inside the heat exchanger. The increase in thermal effectiveness of the heat exchanger compensates for energy losses incurred by diverting a portion of the compressor air flow for cooling.

摘要： A system includes a power cycle and a cooling cycle. The power cycle includes a first compressor, a recuperative heat exchanger, a waste-heat heat exchanger, and a turbine. The turbine includes a drive shaft coupled to the first compressor. The working fluid from the waste-heat heat exchanger drives the turbine, the drive shaft, and the first compressor. The recuperative heat exchanger cools the working fluid from the turbine, and at least one ram-air heat exchanger further cools the working fluid from the recuperative heat exchanger. The first compressor is configured to pressurize the working fluid from the at least one ram-air heat exchanger. The cooling cycle includes a pump, an isenthalpic valve, an ambient air heat exchanger, and a second compressor. The cooling cycle cools the working fluid and ambient air and is connected to the power cycle in the at least one ram-air heat exchanger.

摘要： Two turboshaft engines are interwoven so as to exchange thermal energy by heat exchangers which improve their efficiency, without greatly increasing head losses since the pipes imposed to serve the exchangers are short and include a single bend.

摘要： The present disclosure provides systems and methods for power production. In particular, the systems and methods utilize the addition of heat to an expanded turbine exhaust stream in order to increase the available quantity of heat for recuperation and use therein for heating a compressed carbon dioxide stream for recycle back to a combustor of the power production system and method.

摘要： A turbocharger system includes a low pressure turbocharger (LPT) that includes an LPT compressor and an LPT turbine. The turbocharger system is configured to divide ambient air compressed by the LPT compressor into a heat exchanger flow and an HPT compressor inlet flow. The turbocharger system also includes a high pressure turbocharger (HPT) that includes an HPT compressor and an HPT turbine. The HPT compressor is configured to further compress the HPT compressor inlet flow, which is then channeled to a rotary machine as auxiliary compressed air. The turbocharger system further includes a heat exchanger configured to place the heat exchanger flow into thermal communication with exhaust gases associated with the rotary machine. The discharged heat exchanger flow is divided into parallel streams, and the LPT turbine and the HPT turbine are each configured to be driven by a respective one of the parallel streams.
