<P>PROBLEM TO BE SOLVED: To provide a multi-pressure type radial turbine system which can attain high efficiency and low cost of a binary power generation system or the like using a Rankine cycle. <P>SOLUTION: The multi-pressure type radial turbine system includes: a high-pressure pump 21H and a low-pressure pump 21L which boost a sucked liquid-phase heat medium to respectively different pressures; a high-pressure evaporator 23H and a low-pressure evaporator 23L which suck the heat of the liquid-phase heat medium sent out from the high-pressure pump 21H and the low-pressure pump 21L respectively into vaporization; one set of multi-pressure type radial turbine 25 which inflates the gas-phase heat medium different in pressure and temperature supplied respectively from the high-pressure evaporator 23H and the low-pressure evaporator 23L for obtaining the output; and a condenser 27 which discharges, to a low-pressure heat source, the heat of the gas-phase heat medium inflated in the multi-pressure type radial turbine 25 into condensation. A cycle circuit C in which the heat medium circulates while repeating a gas-liquid state change. <P>COPYRIGHT: (C)2013,JPO&INPIT |
