COMPRESSOR SYSTEM INCLUDING GEAR INTEGRATED SCREW EXPANDER

摘要

A compressor system includes a gear box having a first drive gear, a second drive gear and a first driven gear. A prime mover is coupled to the first drive gear and is operable to input rotational power to the gear box and a compressor is coupled to the first driven gear and is operable in response to rotation of the first driven gear to produce a flow of compressed gas. A heat exchanger is positioned to receive the flow of compressed gas and a flow of fluid and is operable to cool the flow of compressed gas and heat the flow of fluid to produce a flow of heated gas. A screw expander is coupled to the second drive gear and is operable in response to the flow of heated gas to input rotational power to the gear box.
