Abstract: Proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. More particularly, proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. The ship cogeneration system is configured to generate electric power by recovering waste heat generated from an LNG engine and providing high-temperature and high-pressure steam discharged from the economizer to an evaporator of an organic Rankine cycle. The ship cogeneration system is capable of removing soot generated on a contact surface between the exhaust gas of the LNG engine and the economizer by using some of the high-temperature and high-pressure steam.

Abstract: An example system includes an engine and an exhaust passage fluidly coupled to the engine. A waste heat recovery system includes a boiler operatively coupled to the exhaust passage, and a condenser fluidly coupled to the boiler. An integrated cooling system includes an engine cooling circuit, a waste heat recovery cooling circuit, a waste heat recovery bypass valve, and a controller. The waste heat recovery bypass valve is operatively coupled to the exhaust passage upstream of the boiler, and is selectively controllable so as to direct at least a portion of the exhaust gas through an exhaust bypass passage so as to bypass the boiler. The controller is in operative communication with the waste heat recovery bypass valve. The controller is structured to determine a cooling demand of the engine, and to control a valve position of the waste heat recovery bypass valve based on the cooling demand.

Abstract: A device for recovering the waste heat energy having a Clausius-Rankine circuit with a line system conveying a working medium via which at least one vaporizer for vaporizing the working medium, an expansion device for expanding the vaporized working medium to produce mechanical work, a condenser for fluidizing the vaporized and expanded working medium as well as a delivery pump for condensing and conveying the working medium through the line system are fluidically connected to one another. A compensation tank supplies additional working medium volume and is connected to a fluid line and can be fluidically separated from the line system via a valve that is controllable via a control device connected to a sensor for detecting working medium temperature and/or pressure, such that a working medium volume is transferred from the compensation tank into the line system or from the line system into the compensation tank.

Abstract: A heat energy recovery system for an engine, and a vehicle having an engine and a heat energy recovery system. The heat energy recovery system has a liquid supply, one or more evaporators, an expander, a condenser, and a port. The one or more evaporators are fluidly connected to the liquid supply and configured to heat liquid to a superheated vapour using heat energy from an engine. The expander is fluidly connected to the one or more evaporators and configured to be driven by the superheated vapour. The expander has an expander outlet. The condenser has an inlet fluidly connected to the expander outlet. The port is upstream of the condenser inlet and configured for injection of liquid from the liquid supply to reduce the temperature of fluid entering the condenser. The port is further configured for injection of liquid between the expander outlet and the condenser inlet.
