Abstract (en)

[origin: WO9638703A1] A water jet blower for cleaning thermal installations has a water lance (6) movably arranged (5) with its mouth on or in a hatch (2). The water lance (6) can project a water jet on the wall areas that can be reached from the hatch (2) through the thermal installation in operation filled with flames and/or smoke gas. The water jet blower may be moved by at least one moving element (8.1, 8.2, 8.3) joined at one end to the water jet blower and at the other end directly joined to the thermal installation. Displacement sensors are provided to accurately determine the position of the water lance (6). Preferably three moving elements (8.1, 8.2, 8.3) are used whose attachment points (9.1, 9.2, 9.3) form with the point of displacement (5) of the water lance (6) in particular angles from approximately 80 DEG to 140 DEG . This water jet blower may be used even in unfavourable conditions, as far as the space available is concerned, and can project any desired, predeterminable patterns with various speed profiles.
