翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Closed-cycle gas turbine ： ウィキペディア英語版 Closed-cycle gas turbine A closed-cycle gas turbine is a turbine that uses a gas (e.g. air, nitrogen, helium, argon,〔(Nitrogen or Air Versus Helium for Nuclear Closed Cycle Gas Turbines | Atomic Insights )〕〔(AN ASSESSMENT OF THE BRAYTON CYCLE FOR HIGH PERFORMANCE POWER PLANTS )〕 etc.) for the working fluid as part of a closed thermodynamic system. Heat is supplied from an external source.〔 Note: front matter (including preface and introduction; (PDF link )) is open access.〕 Such recirculating turbines follow the Brayton cycle.〔Thermodynamics and Propulsion: (Brayton Cycle )〕〔(A REVIEW OF HELIUM GAS TURBINE TECHNOLOGY FOR HIGH-TEMPERATURE GAS-COOLED REACTORS )〕 ==Background== The initial patent for a closed-cycle gas turbine (CCGT) was issued in 1935 and they were first used commercially in 1939.〔 Seven CCGT units were built in Switzerland and Germany by 1978.〔 Historically, CCGTs found most use as external combustion engines "with fuels such as bituminous coal, brown coal and blast furnace gas" but were superseded by open cycle gas turbines using clean-burning fuels (e.g. "gas or light oil"), especially in highly efficient combined cycle systems.〔 Air-based CCGT systems have demonstrated very high availability and reliability. The most notable helium-based system thus far was ''Oberhausen 2'', a 50 megawatt cogeneration plant that operated from 1975 to 1987 in Germany. Compared to Europe where the technology was originally developed, CCGT is not well known in the US. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Closed-cycle gas turbine」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
