Abstract:

The specification discloses an apparatus and method for separating liquid droplets carried in a gas wherein the gas is conducted at a subsonic velocity below about Mach 0. 7 through a conduit, the walls of which define successive, generally oppositely directed arcuate bends to cause transverse movement of the droplets toward and into contact with the walls by centrifugal force and in a manner which avoids conditions giving rise to flow separation and any attendant turbulence and pressure drop. The walls include a porous medium covering at least a portion of the surface thereof and through which liquid directed against the wall is withdrawn from the conduit. According to one aspect of the invention, a porous medium is provided on the stator blades of a turbine power generator to enable removal of accumulated liquid thereon and thereby reduce rotor blade erosion and power losses associated with dribble from the stator blades onto the rotor blades.
