Title:
POWER GENERATING APPARATUS, POWER GENERATING METHOD, DECOMPOSITION-GAS BOILER, AND DECOMPOSITION-GAS TURBINE
Document Type and Number:
WIPO Patent Application WO/2013/124997
Kind Code:
A1
Abstract:
Provided are a power generating apparatus, a power generating method, a decomposition-gas boiler, and a decomposition-gas turbine with which nitrous oxide can be used as an environmentally friendly energy source. A fuel gas including nitrous oxide (N2O) is supplied to a decomposition reactor (22) in which a catalyst (21) for decomposing nitrous oxide is disposed, and the nitrous oxide included in the fuel gas is decomposed using the catalyst (21). Steam is generated by a decomposition-gas boiler by way of heat recovery from decomposition gas (N2, O2) generated by decomposing the nitrous oxide, the steam generated by the decomposition-gas boiler is used to drive the rotation of a steam turbine to obtain motive power, and the motive power is subsequently used to drive a generator to obtain electrical power. Alternatively, the decomposition gas (N2, O2) generated by decomposing the nitrous oxide is used to drive the rotation of a decomposition-gas turbine to obtain motive power, and the motive power is subsequently used to drive the generator to obtain electrical power.
