Ejector

Ejectors are devices that transfer kinetic energy from one medium travelling at a higher velocity to another.
Working according to Bernoulli's law, ejectors create in the narrowing section of the reduced pressure of one medium, which causes suction into the flow of another medium, which is then carried away and removed from the place of suction by the energy of the first medium.
Steam ejectors are jet apparatuses for sucking gases from a confined space and maintaining rarefaction.
The working steam enters the nozzle, where it expands to a pressure value equal to the pressure in the suction chamber and acquires a high velocity.
The working steam jet flowing out of the nozzle captures the vapour-air mixture injected into the ejector receiving chamber from the condenser and enters with it into the narrowing part of the diffuser or mixing chamber.
The latter consists of a conical part and a cylindrical section.
In the mixing chamber, including the cylindrical section, velocity equalisation across the flow cross-section takes place, accompanied ...
