摘要： A multi-stage expansion device having bypass capabilities and a variable speed drive is disclosed. In one example, the multi-stage expansion device has a housing within which a first stage, a second stage, and a third stage are housed. The housing may also be configured with internal working fluid passageways to direct a working fluid from the first stage to the second stage and/or from the second stage to the third stage. Each of the stages may include a pair of non-contacting rotors that are mechanically connected to each other and to a power output device such that energy extracted from the working fluid is converted to mechanical work at the output device. In one example, a bypass line is provided to bypass working fluid around the first stage and a bypass line is provided to bypass working fluid around the second stage.

摘要： A multi-stage, two-flow, axial flow expander close-coupled to a driven machine, such as a generator. The expander includes one or more expansion stages separated by a series of flow stream dividers that separate each expansion stage into outer and inner expander flowpaths. Working fluid at a first temperature is directed into the outer expander flowpath for expansion, and working fluid at a second, lesser temperature is directed into the inner expander flowpath for expansion. Expansion of the working fluid drives the driven machine.

摘要： A novel Rankine cycle system configured to convert waste heat into mechanical and/or electrical energy is provided. In one aspect, the system provided by the present invention comprises a novel configuration of the components of a conventional Rankine cycle system; conduits, ducts, heaters, expanders, heat exchangers, condensers and pumps to provide more efficient energy recovery from a waste heat source. In one aspect, the Rankine cycle system is configured such that an initial waste heat-containing stream is employed to vaporize a first working fluid stream, and a resultant heat depleted waste heat-containing stream is employed to aid in the production of a second vaporized working fluid stream. The Rankine cycle system is adapted for the use of supercritical carbon dioxide as the working fluid.

摘要： A novel Rankine cycle system configured to convert waste heat into mechanical and/or electrical energy is provided. The system provided by the present invention comprises a novel configuration of the components of a conventional Rankine cycle system; conduits, ducts, heaters, expanders, heat exchangers, condensers and pumps to provide more efficient energy recovery from a waste heat source. In one aspect, the Rankine cycle system is configured such that three distinct condensed working fluid streams are employed at various stages in the waste heat recovery cycle. A first condensed working fluid stream is vaporized by an expanded first vaporized working fluid stream, a second condensed working fluid stream absorbs heat from an expanded second vaporized working fluid stream, and a third condensed working fluid stream removes heat directly from a waste heat-containing stream. The Rankine cycle system is adapted for the use of supercritical carbon dioxide as the working fluid.
