ABSTRACT:
A steam spray tube with an inlet line (16) for steam, a nozzle arrangement (33) and a valve (19) positioned between the inlet line and the nozzle arrangement is described. With such a steam spray tube, adequate moistening of a web to be moistened can be assured even at high web velocities. To do so, an essentially straight acceleration channel (35) is arranged downstream from valve (19) in the direction of flow of the steam and a nozzle channel (36) to the nozzle arrangement (33) branches off from the acceleration channel at a predetermined distance from the end (37) of the acceleration channel (35).
