摘要： An integrated power plant based on a molten carbonate type fuel cell and a gas turbine combined plant comprising a gas turbine, a steam turbine and a common generator driven by the gas turbine and the steam turbine is disclosed, where a reformer for a fuel gas to the anode of the fuel cell is heated through heat exchange with the cathode off-gas from the fuel cell to obtain the necessary heat for the reforming, and a portion of the anode off-gas from the fuel cell is combusted in a separate burner to form a CO.sub.2 recycle to the cathode, while most of the remaining anode off-gas is supplied to the gas turbine combustor. The existing gas turbine combined plant can be used, as it is, without any substantial modification, and the present fuel cell power generation plant can be simply added thereto as an auxiliary unit.

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： A coal gasification composite power generating plant has a coal gasification plant and a composite power generating plant. The coal gasification plant has a low-pressure steam generator for recovering heat from the furnace wall of a pressurized fluidized bed type coal gasification furnace, and a high-pressure steam generator disposed at the outlet of the gasification furnace and adapted to recover heat from the unrefined gas coming from the gasification furnace. The composite power generating plant includes a gas turbine which uses the gas generated in the gasification plant as the fuel gas, a boiler for recovering heat from the exhaust gas of the gas turbine, and high-pressure and low-pressure steam turbines which operate with the steam generated by the boiler. The high-pressure steam generated in the high-pressure steam generator is introduced to the high-pressure steam turbine, while the steam generated in the low-pressure steam generator is introduced into the low-pressure steam turbine, thereby to effectively recover the energy.
