摘要
自行研发了用于有机朗肯循环低品位热能发电系统的向心透平,并以压缩空气为工质,在透平性能实验台上对向心透平的性能进行了测试研究。实验结果表明:透平的最高转速为63 945r/min时,透平进出口温降最高为51.7℃,透平的膨胀功率为4.369kW,发电机的电功率为2.567kW;在不同流量、不同入口温度条件下,使透平在额定转速附近运行,转速为59 553 r/min时透平效率和机电效率同时达到了最大值:65.3%和79.1%,而透平膨胀功率为2.809kW,稍大于设计功率;在不同条件下,得到透平的最大效率为65.7%,发电机的最大机电效率为79.5%。因此,研发的向心透平具有较好的性能。
The radial inflow turbine suitable for organic Rankine cycle （ORC） waste heat power generation was self-designed and developed. By using compressed air as the working fluid, the performance test of the radial inflow turbine was completed on turbine performance test rig. The experimental results show that the maximum rotational speed of the turbine is up to 63 945r/min, the highest temperature drop is up to 51.7℃, the maximum output power of the turbine is 4.369kW and the maximum efficiency of the turbine is 65.7%. The turbine was operated near the rated speed under diverse working conditions for different mass flow rate and inlet temperature. When the rotational speed is 59 553 r/min, the turbine efficiency and electromechanical efficiency achieve simultaneously maximum value： 65.3% and 79.1%, and the output power of the turbine is up to 2.809kW which was basically consistent with the design power. Additionally, under different conditions the maximum electric power of the generator and electromechanical efficiency are 2.567kW and 79.5%, respectively. Consequently, the conclusions can be drawn that the performances of the self-designed and developed radial inflow turbine are satisfied.
