Experimental study on the performance of exhaust steam reclaim device by jetting vortically

In this thesis, the performance of an exhaust steam reclaim device with a swirling flow vane in the spout was studied. The results showed that the injection coefficient decreased as the inlet water pressure and temperature increased respectively. The increasing of inlet steam pressure makes the injection coefficient increase too, and the outlet water pressure doesn't affect it. The resistance coefficient has the opposite variation law. It is improved the heating performance of the device by adding a swirling flow vane while augmented the flow resistance.
