Abstract: In one embodiment, a system includes a generator configured to receive a flow of an organic working fluid. The generator includes a stator and a permanent magnet rotor configured to rotate within the stator to generate electricity. The generator further includes one or more components disposed within the generator and configured to be exposed to the flow of the organic working fluid. The one or more components each include an underlying component, and an encapsulant configured to withstand exposure to the organic working fluid to inhibit contact between the underlying component and the organic working fluid.

Abstract: In one embodiment, a waste heat recovery system includes multiple organic Rankine cycle (ORC) systems arranged in a cascade configuration. Each ORC system includes a heat exchanger that transfers heat to the working fluid to vaporize the working fluid. Each ORC system also includes an integrated power module that expands the working fluid to generate electricity.

Abstract: A waste heat utilization system including a generator configured to receive a flow of an organic working fluid and a method of manufacturing the generator component is provided. The method includes preheating the generator component. The method also includes applying a varnish or an encapsulating layer to the generator component. The method further includes baking the generator component with the varnish applied thereto. The method yet further includes cooling the generator component.

Abstract: 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.
