Abstract

The mixing unit has a plurality of Laval nozzles arranged in the mixing unit, which Laval nozzles are displaced axially with respect to one another in a water steam direction, with the result that the noise emissions are reduced overall.
Claims7
A mixing unit for mixing a flow medium with a cooling medium, comprising
- a pipe conduit section, to which a mixing section is coupled fluidically,
- the mixing section comprising a plurality of Laval nozzles, through which the flow medium can flow,
- injection ducts formed in the Laval nozzles through which the cooling medium flows in such a way that mixing of the flow medium with the cooling medium takes place,
- wherein the Laval nozzles are adjacent to one another and arranged to be offset in relation to one another in the direction of flow of the flow medium, and
- wherein the Laval nozzles are coupled to a displacement device, allowing for displacement of the Laval nozzles during operation.
