摘要： PROBLEM TO BE SOLVED: To provide a hydrogen production plant which can correspond to a change in loads and a change in CO concentration, and can reduce CO in reformed gas by a simple constitution.
SOLUTION: The hydrogen production plant is provided with a controller 27 where the flow rate F of air added to the inflow side of a CO oxidizer 23 is controlled by an air feeder 25, and, at the time when the temperature of reformed gas is equal to or higher than a set temperature TH, the flow rate F of oxygen or oxygen-containing gas to be added is reduced, and, at the time when it is lower than a set temperature TL, the flow rate F is increased. Thus, the amount of CO as a heat generation source increases or reduces in accordance with a change in the amount of the reformed gas caused by a change in loads and a change in the concentration of CO, and, even if the temperature of the reformed gas is made off from the set temperature, the amount of oxygen is increased or reduced in accordance with the same and heat generation value can be controlled, so that the temperature T of the reformed gas can be controlled to the range from the set temperature TL to TH.
