Abstract
An outlet slot (A) for generating a spray curtain (C) is defined by mutually abutting outlet faces of two outer nozzle elements (30) and one central nozzle element (31), all being connected to a support body (10) and separable from each other. At least the two outlet faces (32) of the central nozzle element (31) have a profiled structure roughened, for instance, by sandblasting and to permit discharge of the liquid. Two nozzle slats (40) are connected to the support body (10) and the two nozzle elements (30) are arranged between them. Together with one nozzle slat (40) each the two nozzle elements (30) define a gas outlet slot (D) which likewise extends along the spray curtain (C) to be formed.
