<P>PROBLEM TO BE SOLVED: To find a new cycle structure having overall efficiency higher than that of an existing regeneration Brayton cycle or split cycle and to recover the maximum power from thermal energy of exhaust gas. <P>SOLUTION: In a combined cycle that is an external combustion engine for taking out the maximum power from thermal energy contained in exhaust gas, a circuit comprises one compressor, two turbines, one generator, one precooler, two regenerative heat exchangers, and three exhaust heat boilers, and has a first branching point after deriving from the compressor and a second branching point after passing a high pressure side flow passage of the first regenerative heat exchanger. A portion or all of a working medium circulated in the circuit is carbon dioxide in a supercritical state. By adjusting a preheating amount of the working medium at the first branching point and load ratio of the two turbines at the second branching point, the exhaust heat recovery power plant for recovering the maximum power from thermal energy of exhaust gas and the circuit are connected to a bottoming cycle of an open type gas turbine. <P>COPYRIGHT: (C)2012,JPO&INPIT |
