摘要： An exhaust heat recovery system includes an evaporator, an expander, a condenser, a pump, a circulation flow path, a cooling medium pipe, a bypass pipe, a first valve, a second valve for switching between a state in which the working medium can flow into the coolie medium piping and a state in which the working medium cannot flow therein, and a controller for performing the switching control of the valves. When a condition under which the temperature of the working medium flowing into the condenser becomes higher than or equal to a predetermined temperature is satisfied, the controller controls the second valve to switch to the state in which the working medium can flow into the cooling medium pipe.

摘要： The exhaust heat recovery system (1) comprises: an evaporator (2); an expander (3); a condenser (5); a circulation pump (7); a circulation flow path (6) for circulating a working medium therethrough; cooling medium piping (8) which is connected to the circulation flow path (6) and causes a portion of the working medium sent out from the circulation pump (7) to be diverted to flow into the condenser (5); a cooling-side opening/closing valve (13) for switching between a state in which the working medium can flow into the cooling medium piping (8) and a state in which the working medium cannot flow thereinto; and a control unit (10) for performing the switching control of the cooling-side opening/closing valve (13). When a condition under which the temperature of the working medium flowing into the condenser (5) becomes higher than or equal to a predetermined temperature is satisfied, the control unit (10) controls the cooling-side opening/closing valve (13) to switch to the state in which the working medium can flow into the cooling medium piping (8).

摘要： This invention relates to a method and apparatus for increasing the final feedwater temperature associated with a regenerative Rankine cycle, said cycle commonly used in thermal systems such as conventional power plants, whose steam generators are fired with a fossil fuel and whose regenerative Rankine cycle employs a reheating of the working fluid. This invention involves the placement of an Exergetic Heater System in the feedwater path of the regenerative Rankine cycle. The Exergetic Heater System conditions and heats feedwater such that the temperature of the cycle's final feedwater as it enters the steam generator has reached a desired value. The Exergetic Heater System receives its driving steam from an Intermediate Pressure turbine extraction.

摘要： Systems and methods for transferring and converting heat to a power cycle using a plurality of heat transfer fluids, loops and heat exchange devices to convert heat to useful work and/or power. Power is generated using intermediate heat transfer loops (IHTL) and an intermediate heat transfer fluid (IHTF) to cool the hot exhaust power cycle fluid (PCF) stream that is at or above its critical conditions. The temperature of the IHTF can be increased by 100° C., 150° C., 200° C., 250° C., 300° C., 350° C., 400° C., 450° C., 500° C., 550° C. or more by exchanging heat with the PCF, either directly or indirectly.
