Prime Mover with Recovered Energy Driven Compression of the Working Fluid

摘要

The present invention is a prime mover with recovered energy driven compression for stationary and motor vehicle application. Efficient low compression operation, especially beneficial to small gas turbines, is enabled with either ambient or cryogenic intake air. Recovered energy, liquefied air cooling and re-liquefaction of air by a cryogenic sink minimize motive fluid compression work of a jet compressor driving exhaust gas recirculation. Regenerative heat exchanger terminal temperature difference relative to turbine temperature drop and heat exchanger surface area are reduced.

主权项

1. A gas turbine comprising:
a turbine-generator that is operated by a flow of working fluid; an air heater that heats the working fluid and is in fluid communication with said turbine-generator such that the heated working fluid from said air heater flows into said turbine-generator; a recuperator comprising a recuperator atmospheric side and a recuperator pressurized side, wherein:
said recuperator atmospheric side is in fluid communication with said turbine-generator such that:
at least a portion of working fluid that operates and is expelled by said turbine-generator flows into said recuperator atmospheric side;said recuperator atmospheric side absorbs heat from the working fluid; andsaid recuperator atmospheric side exhausts combustion products of the working fluid to atmosphere;said recuperator pressurized side is in fluid communication with said air heater such that working fluid from said recuperator pressurized side flows into said air heater, wherein the working fluid that flows through said recuperator pressurized side is heated by the heat absorbed by said recuperator atmospheric side; and working fluid compression means for compressing and cooling the working fluid and supplying compressed working fluid to said air heater.
