摘要

A sootblower hub (50) having packing (72) for sealing between a sootblower feed tube (16) and lance tube (14). A packing gland (84) is used which provides a live loading feature for exerting an axial force on the packing (72). The packing gland (84) is comprised of elements (86,88,90,92) which can be separately assembled in a manner which maintains a preload on the packing loading spring (90), even when it is disassembled from the sootblowing mechanism. Once the packing gland (84) is installed into a sootblower carriage (18) a preload maintaining member (92) can be actuated to enable the axial loading force created by the spring (90) to be transferred to the packing (72).
