Boosters

Boosters are ejectors designed to compress relatively large quantities of water vapor or other condensable vapors from a low absolute suction pressure to a discharge pressure such that the mixture may be readily condensed. At a suction pressure of 0.2” HgA (5 torr) or lower, it may be necessary to enclose the inlet diffuser section, and possibly the steam nozzle, in a steam jacket to prevent the formation of ice in the flow path.
