PURPOSE: To surely control the temperature of a reformer to efficiently operate a plant and to decrease environmental pollution by installing a combustion furnace which uses flammable material-containing gas in the outlet of a fuel cell as main fuel, a heat exchanger for heat recovery, and a reformer of methanol vapor.
CONSTITUTION: A combustion furnace 21 which uses falamble material-containing gas in the outlet of a fuel cell as main fuel is installed. A heat exchanger comprising a heater 22, an evaporator 23, a heating medium evaporator 24 or a heating medium heater, denitration equipment 25, and an air preheater 25 is installed. A methanol heater 31 using steam as power source, a methanol evaporator 32, and a reformer 27 of methanol vapor are installed. These facilities are connected with pipelines. Since the pressure of heating medium can easily be controlled with a pressure control valve 47, the temperature of the reformer 27 is surely controlled. By combining the methanol evaporator 32, the heating medium evaporator 24, and the air preheater 26, rational, effective heat recovery is made possible and a plant is efficiently operated.
