Title:
ELECTRIC POWER LEVELING METHOD AND METHANE HYDRATE COLD-HEAT UTILIZATION POWER GENERATING SYSTEM IN GAS SUPPLY BUSINESS
Document Type and Number:
WIPO Patent Application WO/2002/077515
Kind Code:
A1
Abstract:
A combined power facility in which a generator is driven by a steam turbine and a gas turbine. A methane hydrate storage tank is annexed to the combined power facility, so that the cold water which is produced upon decomposition of the methane hydrate in the methane hydrate storage tank is introduced into an suction air cooler attached to the gas turbine to cool combustion suction air and is used as cooling water for the steam turbine condenser. Further, in other seasons than summer, part of the exhaust gas discharged from the gas turbine is mixed with combustion suction air so as to hold the combustion suction air at a predetermined temperature throughout the year.
