<p>In a shutdown method for a reforming apparatus, shutdown is carried out without exhausting untreated carbon monoxide as it is, the durability of catalyzer is inhibited from being lowered despite the repetition of start-up and shutdown, the shutdown is carried out without lowering the durability of a reforming section, and the shutdown is carried out with a little loss in energy. A control device for the reforming apparatus commences purge of residual gas in the reforming apparatus by stopping the supply of reforming fuel to the reforming section, by stopping the supply of reforming water to an evaporator section, and by supplying the reforming water remaining in the evaporator section to the reforming section while evaporating the reforming water by the utilization of the remaining heat of the reforming apparatus and flows oxidizing air for a predetermined period of time only from the time point of the commencement of the purge.</p> |
