PURPOSE:To effectively utilize energy of exhaust gas, by providing an evaporator of a working medium, used in an electric power plant utilizing a Rankine cycle, in the downstream side of exhaust gas in a methanol preprocessor further a superheater in the upstream side. CONSTITUTION:A combined electric power plant is constituted by an electric power plant 10 using methanol as fuel and a Rankine cycle electric power plant 30 utilizing a medium of low boiling point. And the electric power plant 30 is connected through a pipe 18 in a circle state successively with a low boiling point medium turbine 12, condenser 14, feed water pump 17, evaporator 11 and a superheater 13 while constituted from a generator 15 driven by the turbine 12. Here the superheater 13, being positioned in the upstream side of a preprocessor 1 in the electric power plant 10, is set in a pipe 19 for exhaust gas, discharged from a gas turbine 2, to pass. While the evaporator 11, being positioned in the downstream side of the preprocessor 1, is set in a pipe 20 for exhaust gas, discharged from the preprocessor 1, to pass. |
