Abstract
A combined-cycle power generation system using waste matter as a fuel, which can be expected to improve in power generation efficiency without using an additional fuel. The system has a corrosive exhaust gas source (waste exhaust gas source) (1), a closed-cycle gas turbine (2), and a Kalina-cycle steam turbine (3). A ceramic heat exchanger (6) for the closed-cycle gas turbine (2) is disposed on a high-temperature side of the corrosive exhaust gas source (1). A heat exchanger (7) heats a mixed ammonia water fluid (11) for the Kalina-cycle steam turbine (3) by a high-temperature side exhaust gas from the closed-cycle gas turbine. A heat exchanger (9) evaporates a condensate of the mixed ammonia-water fluid (11) by heat remaining in the exhaust gas from the closed-cycle gas turbine. A heat exchanger (10) for the Kalina-cycle steam turbine is disposed on a low-temperature side of the corrosive exhaust gas source (1) to evaporate the mixed ammonia-water fluid (11) by heat remaining in the waste exhaust gas.
