高温气冷堆能提供 90 0℃以上的出口温度 ,而蒸汽透平循环的工质最高温度只有 550℃左右 ,不能有效地利用高温气冷堆的高温潜力。 10MW高温气冷堆 (HTR -10 )采用的气体透平和蒸汽透平联合循环方案 ,不仅跟目前的高温气冷堆低入口温度相匹配 ,而且有助于学习和掌握直接和间接气体透平循环技术 ,积累并获得中间换热器、气体透平和其它设备的设计、建造和运行经验。中间换热器是采用联合循环的HTR -10的关键设备。本文将描述其独特的结构设计 ,热工水力特性等
High-temperature gas-cooled reactor can provide 90 0 ℃ above the outlet temperature, and steam turbine cycle of the maximum working fluid temperature is only 550 ℃, can not effectively use the high-temperature gas-cooled reactor high temperature potential. The gas turbine and steam turbine combined cycle solution used in the 10MW HTR-10 (HTR-10) not only matches the current low inlet temperature of the HTGR but also helps to learn and master the direct and indirect gas turbine cycles Technology, gaining experience in the design, construction and operation of intermediate heat exchangers, gas turbines and other equipment. The intermediate heat exchanger is the key equipment for the combined cycle HTR-10. This article will describe its unique structural design, thermal and hydraulic properties
