🀄 Cara Kerja Steam Ejector

Dalam steam jet ejector, steam yang telah dipakai dikondensasi dengan mencampurkannya dengan air. Daya hisap dan vacuum akhir yang tercapai seringkali tergantung pada tekanan awal pancaran, tekanan uap kondensate dan konstruksi pompa (jumlah langkah kerjanya). 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. 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. In the steam ejector is necessary to optimize the three components include: models of steam ejectors, problem formulation, and optimization techniques. 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. Jet ejector Berdasarkan motive fluid-nya, ada 2 jenis jet ejector, yaitu: a. Steam jet ejector: alat pembangkit vakum dengan menggunakan steam sebagai media pendorong. evaporator merupakan alat untuk menegevaporasi larutan sehingga prinsip kerjanya merupakan cara kerja dari evaporasi itu sendiri. Cara kerjanya ialah dengan menambahkan kalor 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. 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: The main components of a steam ejector or steam injector system are the motive nozzle, diffuser, throat, suction chamber, and exhaust chamber. The motive nozzle is responsible for taking the input fluid (usually steam) at high pressure and transforming it into kinetic energy. rDJv.
