摘要： In one embodiment, a system includes a valve system switchable between a waste heat recovery position configured to direct incoming exhaust gas through an interior volume of an exhaust section of an engine and a bypass position configured to direct the incoming exhaust gas through a bypass duct to bypass a heat recovery boiler disposed within the interior volume. The system also includes an inert gas purging system configured to inject an inert gas into the interior volume to displace residual exhaust gas from the interior volume.

摘要： An ORC system configured to limit temperature of a working fluid below a threshold temperature is provided. The ORC system includes a heat source configured to convey a waste heat fluid. The ORC system also includes a heat exchanger coupled to the heat source. The heat exchanger includes an evaporator configured to receive the waste heat fluid from the heat source and vaporize the working fluid, wherein the evaporator is further configured to allow heat exchange between the waste heat fluid and the vaporized working fluid at an elevated temperature and further produce an evaporator outlet flow including a lower temperature waste heat fluid. The heat exchanger also includes a superheater configured to receive the lower temperature waste heat fluid from the evaporator, wherein the superheater is further configured to allow heat exchange between the lower temperature waste heat fluid and a relatively higher temperature working fluid contained in the superheater and further produce a superheater outlet flow comprising an elevated temperature waste heat fluid. The heat exchanger further includes a preheater configured to receive the elevated temperature waste heat fluid from the superheater and allow heat exchange with a relatively lower temperature working fluid in a liquid state contained in the preheater.

摘要： An ORC system configured to limit temperature of a working fluid below a threshold temperature is provided. The ORC system includes a heat source configured to provide waste heat fluid. The ORC system also includes a heat exchanger coupled to the heat source, wherein the heat exchanger includes multiple external or internal enhancement features. The external enhancement features are configured to reduce a first heat transfer coefficient between the working fluid and the waste heat fluid from the heat source, external to the heat exchanger. The internal enhancement features are configured to increase a second heat transfer coefficient between the working fluid and the waste heat fluid from a heat source, internal to the heat exchanger.
