The Experimental Study on Performance of Single Screw Expander with Air as Working Fluid

Abstract:

A new single screw expansion machine was developed in order to improve the practical level of low temperature thermal power generation technology and the utilization of waste heat and renewable energy. With compressed air as working fluid, the power, efficiency, gas consumption rate and temperature difference of single screw expander with rotational speed variation had been studied in an established experimental apparatus of single screw expander . The results showed that, the maximum speed of expander reached 3393r/min, the maximum moment of torque reached 22N•m, the maximum power of expander was up to 4.4kW, and the maximum inlet flow rate was 32.9m3/h. The maximum temperature difference between import and export of expander reached 45°C. The lowest gas consumption rate was up to 55.2kg/kW•h, and the maximum total efficiency of expander reached 58.8%.
