Abstract:
An apparatus comprising a main body adapted for use in a gas stream, the main body having a plurality of fluid passages, each fluid passage having an outlet opening on a surface of the main body, wherein fluid can flow from each outlet to cover the surface as a film-like fluid, and wherein the plurality of fluid passages comprise:a first fluid passage through which the fluid can flow from a first outlet to a downstream side of the gas stream on the surface; anda second fluid passage through which the fluid can flow from a second outlet to an upstream side of the gas stream on the surface;the first outlet and the second outlet being separately located along a direction perpendicular to the direction of the gas stream on the surface so the fluid flowing from the second outlet collides with the gas stream and suppresses roll up of the fluid flowing from the first outlet.
