The two-fluid cycle is considered for municipal solid waste (MSW) -burned electric power generation, using six kinds of working fluid such as NH3, C5H12, C6H6, and H2O at the bottoming cycle. The performance characteristics of the two-fluid cycle are obtained at topping steam temperatures of 395 and 495°C. The optimum cycle conditions, which maximize the plant's thermal efficiency, are determined for the respective working fluid. It is shown that the plant's thermal efficiency of the two-fluid cycle was increased to 25.3% from 19.0%, using C6H6 as the working fluid under the main steam temperature of 395°C by superheating the bottoming vapor.
