Abstract

A water lance blower for cleaning heating installations, wherein a water lance (6) is movably (5) arranged with its mouth on or in a hatch (2) and can blow a water jet through the heating installation, which is in operation and is flowed through with flames and/or smoke, onto wall areas (A-E) which can be reached from the hatch (2), wherein the water lance (6) is configured in a shortened manner, in that the water supply (11, 10) is bent one or more times by in total more than 70.degree., preferably more than 90.degree. (20, 24; 39). In addition steadying of the flow profile is effected by an expanded calming volume (20) arranged in the end of the water lance (6) lying outside the heating installation, in particular an approximately spherical volume (20), so that the jet quality of the water lance is not impaired. The shortened water lance permits more simple drive mechanisms and adjustment to restricted spatial arrangements.
