STEAM EJECTOR WORKING PRINCIPLE

‼️STEAM EJECTOR WORKING PRINCIPLE‼️ 

An Ejector is a device used to suck the gas or vapor from the desired vessel or system. An ejector is similar to an of vacuum pump or compressor. The ejector is a static piece of equipment with no moving parts consist of 4 components:-

 1️⃣ The Motive Nozzle

 2️⃣ Motive Chest

 3️⃣ Suction chamber

 4️⃣ Diffuser 

How it Works

1️⃣ The ejector converts pressure energy of motive steam or other working fluid into velocity. 

2️⃣ Thermodynamic-ally, high velocity is achieved through adiabatic expansion of motive fluid through a convergent-divergent nozzle.

3️⃣ This expansion of the motive fluid from the motive pressure to the suction fluid operating pressure results in supersonic velocity at the nozzle exit. The motive fluid expands to a pressure equal to the suction fluid pressure, This creates a driving force to bring suction fluid into an ejector.

4️⃣ the velocity exiting a motive fluid nozzle is very high. High-velocity motive fluid entrails and mixes with the suction fluid. The resulting mixture is still supersonic. As the mixture passes through the convergent throat and divergent sections of the diffuser, high velocity is converted back to pressure.
