For improving the turbine performance ejector is used, Two types is employed.

First is the "hogging ejector"  or "start-up ejector".  It is used to pull vacuum quickly on a process vessel. Once vacuum is attained, this ejector is shut off and taken off-line. Then the vacuum is maintained by the "holding ejector " system. The hogging  or start-up ejector is usually used in a batch process or on a steam turbine, an application where it is important to get the main vacuum system on-line quickly. Hogging ejectors are usually single-stage, but they have also been built as two- and even three-stage non-condensing systems.
