Principle of steam ejectors.

Question

Accepted Answer

Steam ejectors are devices that use steam to create a vacuum by entraining and compressing gases or vapors.

Steam ejectors work by using a high-pressure steam jet to create a low-pressure zone, which draws in gases or vapors from the surrounding area.
The entrained gases or vapors are then compressed and discharged through a diffuser, which increases their velocity and reduces their pressure.
Steam ejectors are commonly used in industrial processes such as distillation, evaporation, and vacuum drying.
They are also used in refrigeration systems to remove non-condensable gases from the condenser.
The efficiency of a steam ejector depends on factors such as the steam pressure, the size and shape of the ejector, and the properties of the gases or vapors being entrained.
