Vacuum Ejector System

These use large amounts of energy to produce high pressure motive steam for their motive force. The operating cost of Steam ejectors are increasing day by day due to frequent rise in fuel costs of the steam generator. These also require large quantities of water with growing scarcity of water and ever rising prices of L.D.O. for boilers, the steam jet ejector will not be economical for the process industry. The optimum performance of ejectors is achieved only in narrow range of steam pressure. These also create effluent.
