ABSTRACT:
An externally controllable apparatus for cleaning the slag deposits from the inner surfaces of a cyclone burner includes a support structure having a carriage slidably mounted thereon. A fluid-conducting swivel is mounted on the carriage for providing a rotatable coupling to a pipe extending through the cyclone. The carriage is moved along the support by a suitable movement mechanism so that fluid lances movably mounted on the pipe are properly disposed at selectable longitudinal positions within the cyclone burner. The fluid lances are transversely movable so that they can be moved toward or away from the side wall of the cyclone burner. A plurality of pairs of nozzles are used for directing a spray of cleaning fluid toward respective portions of the cyclone. One pair of nozzles is connected to the fluid lances to clean the inner surfaces of the end walls of the cyclone, another pair is connected to the fluid lances to clean the inner surfaces of the inlet and outlet walls and the facing portions of the side wall, and a third pair is connected to the fluid lances to clean the portion of the side wall which extends between the inner mouths of the inlet and outlet walls. The method of cleaning the cyclone utilizes this apparatus to clean these different areas during different time periods.
