Kind Code:
B2
Abstract:
To provide a power generation system capable of performing sterilization treatment on condensed water in a water recovery tank as required.SOLUTION: A power generation system comprises: a reformer 4 for performing water vapor reforming on raw fuel gas; a cell stack 2 for generating power by taking the reformed fuel gas as anode gas and air as cathode gas; and a water recovery tank 88 for performing condensation recovery on a water content included in discharge gas. Condensed water stored in the water recovery tank 88 is sent and supplied to the reformer 4 through a water supply flow passage 90. To the water supply flow passage 90 is connected a circulation flow passage 98 for returning reformed water to the water recovery tank 88. A circulation valve 100 is disposed on the circulation flow passage 98, a water supply valve 104 is provided at a predetermined part of the water supply flow passage 90, and a sterilization heater 96 for performing sterilization treatment is further provided. Abnormality determination means for determining malfunction of the water supply valve 104 performs determination on the basis of a temperature variation state of reformer temperature detection means 110.SELECTED DRAWING: Figure 1
