Summary Water lance blower for cleaning heat exchangers The invention refers to a water lance blower for cleaning heat exchangers, particularly so a combustion-chamber heat-transfer surface in steam boilers, an outlet opening swivel-type supported in the wall of the steam boiler and its rear parts swivel-type suspended. For ensuring a polydirectional movability in a plane at the outlet opening of the water lance blower without contamination and to ensure that the jet meeting the opposite boiler wall describes an exactly defined course, a flange is provided at the outlet opening of the blowpipe (l) which is attached to a segment of a cardan joint (3) with the cardan joint (3) fastened in the combustion-chamber wall (4), the rear part of the blowpipe (1) is arranged in a guide (5) which, at the top and at the bottom, is horizontally shiftable on a vertical spindle (6) with the vertical spindle (6) being shiftable horizontally on a horizontal spindle (7; 8) and with the guide (5) being formed by a housing (9) non-rotatably positioned on the vertical spindle (6) and carrying a fork-shaped accommodation (10) containing a carden-shaped cage (11) which internally is designed as a sleeve (12) holding the blowpipe (1) in an axially shiftable manner. - fig. 1 -
