Integrated Volumetric Energy Recovery and Compression Device

摘要

Power-generation systems including a power plant and a power conversion unit including an energy recovery device and volumetric compressor are disclosed. In one embodiment, the volumetric fluid compressor has first and second meshed rotors and is configured to generate a stream of relatively high-pressure fluid including oxygen to the power plant. In one embodiment, the volumetric fluid energy recovery device having third and fourth meshed rotors, operatively connected to the compressor, and configured to be rotated by the exhaust gas or other fluid deriving energy from the exhaust gas. The system can additionally include a set of timing gears configured to operatively connect the first and second rotors of the compressor to the third and fourth rotors of the energy recovery device, and prevent contact between the first and second rotors and between the third and fourth rotors. The system may also include a rotation transferring link for operative connection between the compressor and the energy recovery device.
