Abstract

The booster-type steam nozzle (10) has a central steam-inlet (20). At least two Laval or Venturi nozzles (30) peripherally distributed and aligned at a first angle at a slat to the lengthwise axis (L) of the steam nozzle . A cool water inlet (40) has at least one branch duct (42) at a second angle at a slant to the lengthwise axis of the steam nozzle and into which the Laval or Venturi nozzles open. The Laval or Venturi nozzles on at least one circle arc are positioned in a core body (12) enclosed in a covering body (14) and open at one end-side into a central hole (22) in the core body. The central hole forms part of the booster-type steam inlet.
