ABSTRACT:
A steam generator with a water lance sprayer for cleaning a surface of a heat exchangers of the steam generator, and more particularly combustion-chamber heat-transfer surfaces in steam boilers, can have an outlet opening swivel-type supported in the wall of the steam generator and its rear parts swivel-type suspended. Such a lance blower is provided with a polydirectional movability in a plane at the outlet opening of the water lance blower without contamination to ensure that the jet meeting the opposite boiler wall describes an exactly defined course. This is done by providing a flange at the outlet opening of the blowpipe, which flange can be attached to a segment of a cardan joint with the cardan joint being fastened in the combustion-chamber wall. The rear part of the blowpipe is preferably arranged in a guide, which guide is vertically shiftable on a vertical spindle, with the vertical spindle being shiftable, at the top and at the bottom thereof, horizontally on a horizontal spindle, and with the guide being formed by a housing that is non-rotatably positioned on the vertical spindle. The guide preferably carries a fork-shaped accommodation containing a cardan-shaped cage which internally is designed as a sleeve for holding the blowpipe in an axially shiftable manner.
