Claim:
1. A power generation apparatus, comprising: a decomposition-gas boiler, generating steam by heat recovery from a decomposition gas produced by decomposition of nitrous oxide, a steam turbine, rotationally driven by the steam generated by the decomposition-gas boiler, and an electric generator, generating electric power by driving the steam turbine; or a decomposition-gas turbine, rotationally driven by decomposition gas produced by decomposition of nitrous oxide and an electric generator, generating electric power by driving the decomposition-gas turbine; wherein the decomposition-gas turbine or the decomposition-gas boiler comprise a decomposition reaction unit, in which a nitrous oxide decomposition catalyst for decomposition of the nitrous oxide is placed and a preheating device for preheating the nitrous oxide decomposition catalyst for decomposition before starting decomposition of the nitrous oxide is provided; and a fuel gas supply device, which supplies a fuel gas comprising nitrous oxide to the decomposition reaction unit, and in the decomposition reaction unit, after decomposition of the nitrous oxide contained in the fuel gas using the nitrous oxide decomposition catalyst, decomposition of a nitrous oxide contained in a fuel gas which is supplied after the decomposition of the nitrous oxide contained in the fuel gas is continued by using the decomposition heat generated by decomposing the nitrous oxide.
