| Abstract: | The performance of supersonic steam-water two-phase flow device composed by a nozzle, mixing chamber and the corresponding valves is studied experimentally when the inlet steam presure is less than 0.2MPa. The experimental results show that the injector can run stably and reliably and the pressures of outlet water is lifted obviously while the inlet steam pressure changes from 0.1 MPa to 0.2 MPa. The characteristics can be used as effective heater in the engineering fields such as power plant, heating, light industry etc. |
