Are being researched and developed in various countries around the world. Particularly, in a power generation facility using a molten carbonate fuel cell using natural gas as a fuel, as shown in FIG. 3, a reformer 10 for reforming a fuel gas 1 such as natural gas into an anode gas 2 containing hydrogen is provided. And a fuel cell 12 that generates electricity from the anode gas 2 and the cathode gas 3 containing oxygen. The anode gas 2 produced by the reformer is supplied to the fuel cell, and most of the anode gas 2 (for example, in the fuel cell) (80%) is supplied to the combustion chamber of the reformer 10 as the anode exhaust gas 4. In the reformer 10, combustible components (hydrogen, carbon monoxide, methane, etc.) in the anode exhaust gas are burned in a combustion chamber,
The reforming pipe is heated by the high-temperature combustion gas to reform the fuel passing through the reforming pipe. The flue gas 5 exiting the reforming chamber is pressurized by a blower and then pressurized air 6 supplied from a pressure recovery device 15.
And becomes the cathode gas 3 to supply necessary carbon dioxide to the cathode side of the fuel cell. A part of the cathode gas (cathode exhaust gas 7) partially reacted in the fuel cell is circulated to the upstream side of the fuel cell by the blower 14, and the remaining pressure is recovered by the pressure recovery device 15 and the heat recovery device 18.
And the heat is recovered and discharged outside the system. In this figure, reference numeral 8 denotes steam.
