An integral packing housing and packing material unit; a method for packing replacement, boiler cleaning; and a method for maintenance of a desired boil er output rating. The integral packing unit includes a housing for removably holding a sacrificial packing material that is configured to form a steam se al 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 th e spindle and the packing material is loaded by applying compression to the packing material. A compression unit is typically coupled to the housing uni t to apply such compression to load the packing material while the packing uni t 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 fro m, the operative position.
