PURPOSE:To improve energy efficiency and safety of power generating system by burning exhaust gas from a fuel cell containing inflammable ingredient perfectly with the second auxiliary burner and supplying cell cooling wafer and a steam-water supplying device with the heat resulting from combustion. CONSTITUTION:Inflammable exhaust gas 22 passing through a fuel cell 8 is let flow into the second auxiliary burner 25, branching from a part of the piping connected to the fuel pole 8' of the fuel cell and the main burner 5 of reforming device 3, mixed with a part 26 of the ejected air 13' from a compressor 13 in order to burn. Burnt exhaust gas 27 from the second auxiliary burner 25 is also introduced into the heating side of a heat exchanger 28 installed in the middle portion of returning line 19' of the cell cooling water connecting the exit of the fuel cell 8 to a steam-water supplying device 2. |
