| 摘 要： | 为满足小型氟盐冷却高温堆（FHR）能量转换需求，开发与之匹配的高效、紧凑、无水冷却动力转换系统，本文对比了超临界二氧化碳（SCO2）、空气、氩气（Ar）、氮气（N2）、氙气（Xe）5种气体工质在不同布雷顿循环构型中的热电转换效率、?效率、?损失分布。研究发现，SCO2布雷顿循环相比其它工质循环具有最高的热电转换效率和?效率，且结构更为紧凑，易于小型化和模块化，与小型氟盐冷却高温堆耦合更具优势；进而对SCO2布雷顿循环进行构型优化，得出匹配小型氟盐冷却高温堆的最佳循环构型方式，构成固有安全模块化小型氟盐冷却高温堆热电转换系统，为西部能源利用提供新研究思路。

| Abstract: | In order to meet the energy conversion requirements of small fluoride cooled high temperature reactor (FHR), an efficient, compact and water-free cooling power conversion system is developed. In this paper, the thermoelectric conversion efficiency, exergy efficiency and exergy loss distribution of supercritical carbon dioxide (SCO2), air, argon (Ar), nitrogen (N2) and xenon (Xe) in different Brayton cycle configurations are compared. It is found that SCO2 Brayton cycle has the highest thermoelectric conversion efficiency and exergy efficiency compared with other working medium cycles, and its structure is more compact, easy to miniaturization and modularization, and has more advantages in coupling with small fluorine salt cooled high temperature reactor; the configuration of SCO2 Brayton cycle is optimized, and the optimal cycle configuration mode matching the small fluoride cooled high-temperature reactor is obtained, which constitutes an inherently safe modular small fluoride cooled high-temperature reactor thermoelectric conversion system, providing a new research idea for energy utilization in the west. |
