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 movable by at least one movement element (8.1, 8.2, 8.3) which is stationarily fixed at one end outside a vertical plane through the point of movement (5) of the water lance (6) to the heating installation and by the other end (7.1, 7.2, 7.3) to the water lance (6), wherein path sensors are provided for precise determination of the position of the water lance (6). Preferably three movement elements (8.1, 8.2, 8.3) are provided, the fixing points (9.1, 9.2, 9.3) of which each form in particular an angle of approximately 80.degree. to 140.degree. to the point of movement (5) of the water lance (6). Such water lance blowers can be installed even when there are unfavorable spatial conditions and perform any freely pre-determinable blowing patterns and speed profiles.
