In each stage of the steam jet ejector, high pressure steam is expanded in a convergent /divergent nozzle. It is one of the types of air ejector which is used in the steam like near the condenser to remove the non condensable gases and some vapour entering into main condenser by an air ejector and it is cooled by the main condensate and released in the ejector condenser.Ī steam is used as the motive fluid to withdraw air and dissolved gases from the condenser by the ejector action. At the point of discharge the pressure energy is converted into the velocity so the velocity will be greater and the pressure will be less during the discharge.ĭivergent nozzle the opposite effect takes place velocity energy is convert into pressure energy, at the point of diffusion there is a low pressure or vacuum is created which is used to suck the other fluid for the motion. V2- velocity of the fluid leaving the nozzle.Īs the pressure energy before entering the convergent nozzle is greater and the velocity is less for the fluid. P2- pressure of the fluid leaving the nozzle. V1- velocity of the fluid entering the nozzle. P1-pressure of the fluid entering the nozzle.
