Abstract
An integral packing housing and packing material unit; a method for packing replacement, boiler cleaning; and a method for maintenance of a desired boiler output rating. The integral packing unit includes a housing for removably holding a sacrificial packing material that is configured to form a steam seal between a sootblower steam tube and lance spindle when the packing unit is installed in an operative position in association with the steam tube and the spindle and the packing material is loaded by applying compression to the packing material. A compression unit is typically coupled to the housing unit to apply such compression to load the packing material while the packing unit is installed in the operative position. The packing unit may also includes a detent mechanism, such set screws, for unloading the packing material to facilitate installing the packing unit on, and removing the packing unit from, the operative position.
