摘要： A turbogenerator system for extracting energy from a fluid stream is described. The system comprises a turbogenerator arranged to be driven by the fluid, the turbogenerator comprising a turbogenerator turbine having an inlet for receiving the fluid and an outlet for exhausting the fluid. The turbogenerator further comprises an alternator arranged on an output shaft of the turbogenerator turbine for the conversion of shaft power into electrical power. A control arrangement is provided for controlling operation of the turbogenerator in dependence upon operating conditions for the turbogenerator system.

摘要： A system for recovering exhaust energy from fluid in an exhaust conduit of a reciprocating engine is described. There is an organic rankine cycle having a heat exchanger arranged to evaporate a working fluid of the organic rankine cycle passing through a low temperature side of the heat exchanger, in which the exhaust conduit is arranged in fluid communication with an inlet of a high temperature side of the heat exchanger for heat exchange of the fluid in the exhaust conduit downstream of the reciprocating engine to the working fluid of the organic rankine cycle. Also a turbine is arranged to receive the working fluid evaporation expansion and then a generator driven by the turbine is arranged to convert shaft power into electric power. A further organic rankine cycle having a heat exchanger arranged to evaporate a working fluid of the further organic rankine cycle passing through a low temperature side of the heat exchanger, in which an engine cooling water conduit is arranged in fluid communication with an inlet of a high temperature side of the heat exchanger for heat exchange of the fluid in the cooling water conduit downstream of the reciprocating engine to the working fluid of the further organic rankine cycle is included and further comprising a further turbine arranged to receive the working fluid evaporation expansion of the further organic rankine cycle, whereby the generator is additionally driven by the further turbine of the further organic rankine cycle to convert shaft power into electric power. The single generator is driven by two independent turbine expanders. A method for operation of the apparatus is also described.
