| 摘 要： |
This research examines the development of a turbine for a supercritical organic Rankine cycle (ORC) power generation system. The study details the design, manufacturing, and performance evaluation of a 100 kWe-class power generation turbine equipped with a magnetic bearing. Furthermore, a supercritical ORC power-generation system is constructed to evaluate the turbine performance. The turbine featured an overall expansion ratio of 9 with a two-stage centrifugal design, and it was integrated with the generator and magnetic bearings within a unified sealed-type casing. To ensure continuous electric power generation, internal turbine cooling devices were installed, and the evaporator connection pipes are modified. The performance tests demonstrate that the turbine produces 100 kW of electric power with an efficiency rate of 75 %. Comparison between the test results and numerical analysis confirms their good agreement. This research elucidates the considerations essential for the development of supercritical ORC turbines.
本研究探讨了超临界有机朗肯循环（ORC）发电系统用涡轮机的开发。研究详细介绍了配备磁悬浮轴承的100 kWe级发电涡轮机的设计、制造及性能评估。此外，还构建了一套超临界ORC发电系统以验证该涡轮机的性能。该涡轮机采用两级离心设计，整体膨胀比为9，并与发电机和磁悬浮轴承集成于一个统一的密封式壳体中。为确保持续发电，安装了内部涡轮机冷却装置，并对蒸发器连接管进行了改造。性能测试表明，该涡轮机可产生100 kW电功率，效率达75%。试验结果与数值分析的对比证实两者具有良好的一致性。本研究阐明了超临界ORC涡轮机开发过程中需要考虑的关键因素。 |
