Single-Stage Steam Jet Ejector

Principle of Operation of Single-Stage Steam Jet Ejectors

Fig. 555G, Fig. 555H, Fig. 556, and Fig. 562 Single-Stage Steam Jet Ejectors are based on the ejector-venturi principle. In operation, steam issuing through an expanding nozzle has its pressure energy converted to velocity energy. A vacuum is created and the high velocity of steam entrains air or gas and the mixture of gas and steam enters the converging end of the venturi, passes through the diffuser where its velocity energy is converted into pressure sufficient to discharge against a predetermined back pressure.
