Thermocompressors: Thermocompressors are ejectors applied to recompressing spent steam and process fluids. The two major functions of ejectors are as follows: Very often, the motive fluid is steam and the device is called a “steam jet ejector.” Basic ejector components are the steam chest, nozzle, suction, throat, diffuser and they discharge (Fig. Instead, it uses a fluid or gas as a motive force. They are easy to install, operate and maintain.Įjector Design:Â Very simply, an ejector is a pumping device.Because they have no moving parts, they are reliable vacuum producers.No source of power is required other than the motive gas.They are especially effective in the chemical industry where an on-site supply of the high-pressure motive gas is available.Įjectors are considered an alternative to mechanical vacuum pumps for a number of reasons:
Steam jet ejectors offer a simple, reliable, low-cost way to produce vacuum.
