Typical duties include filtration, distillation What is the function of a steam ejector? Put simply, steam ejectors are used to create a vacuum within a system. This is done by injecting steam into the system at a high pressure and velocity, which causes the air or other gases inside to be expelled from the system at a high velocity as well. In the event a steam jet-air ejector is used: i. Slowly charge the ejector steam header and warm it up. ii. Start the steam-air ejector by opening its steam supply valve. iii. Open the isolating valves on air evacuating line connecting condenser and steam-air ejector. iv. Basic ejector components are the steam chest, nozzle, suction, throat, diffuser and they discharge (Fig. 1). The two major functions of ejectors are as follows: Thermocompressors: Thermocompressors are ejectors applied to recompressing spent steam and process fluids. Prinsip kerja steam jet ejector adalah mengubah energi tekanan uap penggerak menjadi energi kecepatan yang dikonversikan oleh nozzle. Kemampuan kinerja dari steam jet ejector dipengaruhi oleh nilai entrainment ratio, karena semakin tinggi nilai entrainment ratio menandakan bahwa Non Condensable Gas yang terhisap dari dalam kondensor semakin banyak.

Lutfi Lubihanto Berdasarkan hasil pengujian dan analisa data bahwa ejector dapat bekerja sebagai pompa saat tekanan vacum dibawah tekanan atmosfer dan apabila ejector bekerja sebagai pemanas maka air dalam tangki suction yang terpompa akan tercampur dan terkondensasi dengan uap panas yang mengakibatkan naiknya temperatur air menuju tangki delivery. Single-Stage Steam Ejectors: They cover a range of suction pressure from 30 mm Hg absolute to atmospheric pressure. The discharge pressure is near atmospheric pressure. The design of the steam ejector can be optimized so that the steam consumption is minimized. Two-Stage Steam Ejectors: Cara kerja steam ejector: Saat steam bertekanan tinggi masuk melalui motive fluid , maka steam akan bertambah kecepatannya, akibat penyempitan pada ujung nozzle . Ketika steam keluar dari ujung nozzle , maka steam akan terekspansi dari tekanan tinggi menjadi tekanan rendah. .
