Vacuum Producers: Ejector-based systems are particularly appropriate as primary vacuum producers, particularly where motive steam is almost always available. In the compressors recycle waste steam and low-pressure water vapor discharge, reducing energy consumption by 30% or more. 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 вЂњsteam jet ejector.вЂќ 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.

Very simply, an ejector is a pumping device. They are easy to install, operate and maintain.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.Д®jectors 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.
