    摘要: A fuel cell power plant comprising a fuel cell employing a molten carbonate as an electrolyte, a reformer for reforming fuel into a reactive gas to be supplied into the anode of the cell, an expansion turbine connected to a compressor, a combustor for burning a gas exhausted from the anode and introducing the combustion gas into the cathode of the fuel cell along with a gas compressed by the compressor, and a waste heat recovery system. The power plant is characterized by the provision of another combustor on the passage through which cathode exhaust gas is sent from the cathode to the turbine and a passage for leading a part of the anode exhaust gas to the combustor, whereby unburned gas, included in the anode exhaust gas, is burned with the cathode exhaust gas supplied as oxygen source so that the temperature of the turbine driving gas is raised, as a result, the overall thermal efficiency of the power plant increases.

    摘要: This invention relates to a favorable method of starting a fuel cell power generation system in which fuel is used directly as a heating medium for raising the temperature of said system. Namely, the present invention relates to a method of starting a fuel cell power generation system composed of (a) a reformer which is composed of a reforming part packed with reforming catalyst and a heating part and in which a fuel is fed to the reformer inlet and the fuel is combusted at the heating part, thereby to heat the reforming part and (b) the above-mentioned fuel cell in which the fuel which has been passed through said reformer reforming part is introduced to the anode and the exhaust gas produced at said reformer heating part is fed to the cathode, comprising the step of starting the fuel cell power generation system to ignite the fuel present at the reformer heating part only when the reformer reforming part has been filled with fuel.

    摘要: A combined cycle power plant has a plurality of gas turbine units each having a gas turbine and a heat recovery boiler for generating steam from heat from exhaust gas from the gas turbine. The gas turbine of a first one of the gas turbine units is a steam-cooled gas turbine. Steam turbines are driven by steam from the heat recovery boilers. For start-up of the first gas turbine unit, cooling steam generated in a heat recovery boiler different from not being the heat recovery boiler of the first gas turbine unit is fed to the steam-cooled gas turbine to effect cooling thereof during at least part of the start-up operation of the first gas turbine unit.
