ABSTRACT:
An inlet air demoisturizing system utilizes a plurality of screens between the inlet of a cryogenic engine and a heat exchanger therefor. In a first embodiment, a curtain of liquid air flows on the forward side of the screen to pre-cool the gaseous intake air below the freezing point of water. In a second embodiment, a mist of liquid air is used to pre-cool the air prior to arrival at the screen. The screen traps ice crystals precipitated from the air. In each embodiment, a second sprayer washes the screen with a curtain of liquid water to remove the ice crystals therefrom. Collector troughs collect the liquid air and suspended ice crystals for removal from the engine inlet.
