Abstract

The invention relates to a device for steam generators of the type which in a roof-forming upper part (1) comprises a nozzle (2) in order to lead out water steam from the interior of the generator into a subsequent outlet pipe (3). On the bottom side of the roof part (1), a cup-shaped part (10) placed centrally in relation to the nozzle (2) is arranged with a plurality of mutually separated openings (11) having the purpose of distributing the flow of water steam passing through the cup part into a plurality of equivalent part flows with the object of bringing about a stable main flow through the nozzle; all with the purpose of counteracting unstable flows in the nozzle together with the pipe.
