Steam Jet Ejectors

The basic operating principle of an ejector is to convert pressure energy of high pressure motive steam into velocity. High velocity steam emitted from a motive nozzle is then used to work on the suction fluid. This work occurs in the suction chamber and diffuser inlet. The remaining velocity energy is then turned back into pressure across the diffuser. In simple terms, high pressure motive steam is used to increase the pressure of a fluid that is at a pressure well below motive steam pressure.
