A water lance blower for cleaning heating installations, wherein a water lance (,) is movably (,) arranged with its mouth on or in a hatch (,) 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 (,), wherein the water lance (,) is movable by at least one movement element (,) which is stationarily fixed at one end outside a vertical plane through the point of movement (,) of the water lance (,) to the heating installation and by the other end (,) to the water lance (,), wherein path sensors are provided for precise determination of the position of the water lance (,). Preferably three movement elements (,) are provided, the fixing points (,) of which each form in particular an angle of approximately 80&deg; to 140&deg; to the point of movement (,) of the water lance (,). 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.

Drive system for a water lance blower

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.

Water lance blower positioning system

A method for determining positioning of a controllable blower lance for cleaning a pre-determinable surface of a heatable internal chamber, preferably a combustion chamber, in which deposits form, wherein at least one site of impact of a cleaning medium of the blower lance on a surface to be cleaned of the internal chamber and at least one position of at least a part of the blower lance, by means of which the direction of flow of the cleaning medium out of the blower lance can be determined, are established and recorded and a correlation is established between at least the site of impact and the position, taking into account at least one parameter concerning the internal chamber, wherein by means of the correlation, the positioning of the blower lance can be determined for cleaning the pre-determinable surface. Furthermore a method and a device are provided for cleaning an internal chamber, preferably of a combustion chamber in which deposits form, with a controllable blower lance, the cleaning medium of which must strike a pre-determinable surface to be cleaned of the internal chamber, wherein a pre-determinable control system of the blower lance is superimposed with a correlation associated with the condition in the internal chamber and/or the condition of the cleaning medium, such that the pre-determinable surface to be cleaned is struck according to plan by the cleaning medium whatever the conditions in the internal chamber. Undesired shifting of the cleaning jet of a blower lance, caused by different operating conditions in the internal chamber, can be compensated for in this way.
