The water vapor produced by this reaction is condensed in the exhaust gas condenser 6 and recovered to the main condenser 2 through the condensate return pipe 11. Among these, the outlet exhaust gas flowing out from the exhaust gas recombiner 5 is used as a heating source for the exhaust gas preheater 4. That is, the outlet exhaust gas flows into the heat exchanger 5C in the exhaust gas preheater 4 from the outlet pipe 5b to heat the exhaust gas preheater 4. In order for the hydrogen/oxygen combination reaction to occur in the exhaust gas recombiner 5, the exhaust gas preheater 4 must be
