Patent ID: 7493764

Claim:
An electric power generation/hydrogen production combination plant, comprising: a steam generator; a turbine for generating electric power, using steam generated by the steam generator; a condenser for condensing the steam exhausted from the turbine; a feed water pump and a condenser pump for circulating the condensed water condensed by the condenser to the steam generator via a feed water pipe; feed water heaters arranged upstream and downstream relative to the feed water pump, and downstream of the condenser pump on the feed water pipe, so as to heat feed water to be supplied to the steam generator; a reformer for producing product gas containing hydrogen by processing at least one raw material selected from the group consisting of methanol, ethanol and dimethylether, using steam; a hydrogen separator for separating high purity hydrogen from the product gas; an intermediate loop for circulating a thermal medium in order to supply the heat generated by the steam generator to the reformer; an intermediate heat exchanger for transmitting heat of the steam to the intermediate loop; a heating inlet pipe of the intermediate heat exchanger connected to a heating inlet of the intermediate heat exchanger to supply steam from the steam generator; and heating outlet pipes of the intermediate heat exchanger for connecting a heating outlet of the intermediate heat exchanger and the feed water heaters.
