Abstract
The disclosure is directed to a rotary wall deslagger for cleaning boilers. In accordance with the invention, an extensible rack element is selectively, mechanically coupled to a rotatable lance tube of the rotary wall deslagger to move the lance tube between a working and non-working position. When the selective mechanical coupling between the rack and the lance tube is released, the rack is extensible relative to the lance tube to activate a cleaning fluid discharge means and a driving means to impart a rotary motion to the lance tube. In accordance with another feature of the invention, the selectively-operable, mechanical coupling is released after the lance tube has been moved to its working position and the cleaning fluid discharge means and the rotary drive means are activated by the rack element substantially simultaneously with one another so that the cleaning fluid reaches the discharge nozzle of the lance tube at full pressure as rotation of the lance tube begins.
