摘要： Expansion machines in thermodynamic cycles operate at low pressures, i.e. below 10 bar. The interplay among components including gas generator, expansion machine, heat exchangers and pressure reduction device (absorber or condenser) is optimized, resulting in configurations operating at the lowest achievable cost level. A single stage radial turbine characterized by a pressure ratio of 5-10, a dimensionless speed of about 0.7 and a loading coefficient of 0.7 is a preferred expansion machine for certain thermodynamic cycles involving CO2 gas to permit such radial turbines to operate close to their optimum design specification and highest efficiency level. Methods to handle liquids which may condense within or inside the turbine are also disclosed, as well as methods to handle axial pressure on bearings and methods to protect lubricant in bearings.

摘要： The application relates to a system for using the waste heat of an internal combustion engine through the Clausius-Rankine cycle. Such system prevents operating medium from the Clausius-Rankine cycle from leaking into combustion air or exhaust air. The system has a first flow channel formed by at least one first limiting component and a second flow channel formed by at least one second limiting component. The system has a fluid-conducting connection to the surroundings or to a receiving chamber from the first limiting component and preferably from the second limiting component, so that in the event of a leak the operating medium is conducted into the surroundings or into the receiving chamber.

摘要： Disclosed is a heat energy recovery system including: a heat energy recovery circuit that causes a working medium to circulate by means of a circulation pump to exchange heat with supercharged air from a supercharger via a first heater and exchange heat with steam from an exhaust-gas economizer via a second heater, in order to integrally drive a turbine and a generator; and a controller that performs stop control to stop the circulation pump based on the flow state of the steam in a first steam flow path that causes the steam to flow from the exhaust-gas economizer to a soot blower.

摘要： 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.

摘要： A system for heating one or more components of a heat recovery steam generator that includes a heat-transferring conduit that fluidly connects a high-pressure section of a flow path to a low-pressure section of the flow path. The flow path is defined by a housing of the heat recovery steam generator and configured to direct a heat-containing medium. The heat-transferring conduit is configured to receive the heat-containing medium from the flow path such that the heat-containing medium flows through the heat-transferring conduit via a pressure differential between a first pressure of the heat-containing medium at the high-pressure section and a second pressure of the heat-containing medium at the low-pressure section. The heat-transferring conduit is further configured to heat the one or more components of the heat recovery steam generator via directing the heat-containing medium to be in heating contact with the one or more components.

摘要： 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.

摘要： Provided is a heat-collecting-type power generation system capable of maintaining a stable power generation efficiency even if supplied heat varies. The system includes an evaporator that heats and vaporizes a working medium; a displacement-type expander driven by the vaporized working medium; a power generator driven together with the expander; a condenser that cools and condenses the gas-phase working medium sent from the expander; and a circulation pump that draws the condensed liquid-phase working medium, raises pressure and transports the same to the evaporator, wherein the expander includes a plurality of expansion parts that expand the working medium stepwise, and internal volume ratios of the expansion parts are adjusted in a design phase, so that if at least one of a suction pressure and a discharge pressure of the expander varies, an overall thermal insulation efficiency is 70 percent or more, in a range of the variation.
