摘要
Abstract
The supercritical carbon dioxide Brayton cycle has advantages of high thermal efficiency,low corrosion rate to pipeline equipment and low power cost,hence it was considered as the ideal energy conversion system for sodium-cooled fast reactor.However,its high working pressure leads to large pressure difference between two sides of the heat exchanger,which limits its application.Therefore,the supercritical carbon dioxide double turbine power generation system is established to reduce system working pressure while maintaining high efficiency.The properties of different cycle configurations were compared and the sensitivity of specific parameters was analyzed.Results show that the recompression cycle is most suitable for double-turbine system and the maximum efficiency can reach 42.99%.The sensitivity of the efficiency to the main compressor inlet parameter is the highest,followed by the shunt ratio and turbine inlet parameters,the sensitivity to the turbine distribution ratio is the lowest.关键词
