Abstract
A flow-distributing device comprises a perforated plate (1) which forms a defining wall of a passage or chamber arranged to accommodate a flow of fluid and provided with at least one further defining wall. Deflecting means (1a; 3) extend into the path of said flow adjacent the perforations (2) which are evenly distributed over at least a part of said wall. The deflecting means divide the flow into a plurality of part-flows which pass in mutually the same direction to the other side of the plate via the perforations. The deflecting means may comprise separate nozzles (3) or lips (1a) which have been pressed out of the material when forming the holes. The flow-distributing device may be incorporated in an air-supply device for a furnace, a fluidized bed, an air cooler or heater or the like. In one important application it is used in a substantially box-shaped air-intake screen (10) having a perforated side surface (10b) and an air-supply pipe (11). In this case, the flow-distributing device forms an intermediate wall in the screen, said wall being located at a distance from the perforated side surface to define a pressure chamber (9) on the opposite side of the intermediate wall.
