Abstract
A sootblower hub having packing for sealing between a sootblower feed tube and lance tube. A packing gland is used which provides a live loading feature for exerting an axial force on the packing. The packing gland is comprised of elements which can be separately assembled in a manner which maintains a preload on the packing loading spring, even when it is disassembled from the sootblowing mechanism. Once the packing gland is installed into a sootblower carriage a preload maintaining member can be actuated to enable the axial loading force created by the spring to be transferred to the packing.
