MECHANISM FOR ROTATING AND RECIPROCATING A SOOT BLOWER

摘要

The external cross-section of a soot-blower lance casing(22) has straight sides engaged by a hole with matching straight sides in a bush mounted at the furnace wall(10) and rotated by linkage to a drive. A housing for the lance(12) and the carriage to which it is connected extends backward from the furnace wall in support of the carriage, to form a linkage between the drive and the carriage to provide reciprocation. A carriage has a track connected at the rear end of the lance. This fully supports the back end of the lance and the feed tube to obviate mechanical stress of the seal between the lance and the feed tube.
