Hydrogen production system and power generation system

摘要

The amount of high-temperature steam supplied from external equipment is reduced. Provided is a hydrogen production system (1) including a reactor (3) that allows a humidified process fluid output from a humidifier (2) to react in the presence of a catalyst to transform carbon monoxide in the process fluid into carbon dioxide; a second channel (B) through which the high-temperature process fluid that has reacted in the reactor (3) flows; a circulation channel (C) through which excess water in the humidifier (2) is circulated; and a first heat exchanger (7), disposed at an intersection of the circulation channel (C) and the second channel (B), for heat exchange between the high-temperature process fluid that has reacted in the reactor (3) and the fluid circulated through the circulation channel (C).
