PURPOSE:To concurrently attain blow down and improve the power generating efficiency and high-temperature heat recovery percentage by connecting the blow-down water circuit of a steam generator and a fuel gas circuit to a boosting mixer, and connecting a mixer circuit to a fuel reformer CONSTITUTION:A blow-down water circuit L1 of blow-down water E of a steam generator 5 is connected to a boosting mixer 7, and a fuel gas circuit L2 of fuel gas is connected to the boosting mixer 7. A mixed gas circuit L3 of the boosting mixer 7 is connected to a fuel reformer 6. The boosting mixer 7 is constituted of an ejector. When the high-temperature, high-pressure blow-down water E is injected, the blow-down water E is diffused, decompressed, and converted into the vapor phase, and the fuel gas D is sucked. The fuel gas D and the moisture are mixed and boosted into the high-temperature mixed gas F and fed to the fuel reformer 6. Blow down is concurrently attained in a fuel cell power generating device, the heat quantity lost by blow down in the past is recovered as the high-temperature heat, and the power generating efficiency and high-temperature heat recovery percentage can be improved. |
