PURPOSE:To improve cycle efficiency as well as to compose it economically, by installing an extraction port between an inlet port and an outlet port, and extracting a gas medium under way for expansion with a vane type expander of displacement in type. CONSTITUTION:An extraction port 9 is set up on the way between an inlet port 11 interconnected to an inlet part 7 and an outlet port 8 interconnected to an outlet part 5 of a casing 3, further connected to an extraction outlet part 6 via an extraction steam pipe 10. A high pressure gas 22 from a boiler 36 turns to a low pressure gas 23 in an expander 37 upon adiabatic expansion and then condensed 24 when reached to a condenser 35, and after the temperature gets raised 27 by dint of a low pressure pump 31, it is mixed with a medium pressure gas 26 via a regenerator 32. With these procedures, enthalpy of the regenerative cycle increases 28 and then pressure grows high 21 still more by dint of a high pressure pump 33, returning to the boiler 36. Therefore, input energies in the boiler 36 can be lessened, besides much improvement in efficiency is obtained. |
