PURPOSE: To enable sootblower members to be maintained or taken out through the open top and bottom of a box, which encloses a carriage assembly and a lance tube cooperating with the inboard and outboard end walls, by accessing the carriage and the lance tube from above or below through the openings at the apex and bottom of the box. CONSTITUTION: Side panels 120 cooperate with an inboard end wall 114 and an outboard end wall 116a to define a rectangularly shaped box for enclosing therein a carriage 18 and a lance tube 14, The inboard end wall 114 is fixed to a boiler wall, that is, a wall box and includes a lance opening 118, which allows the lance tube 14 to access a port of the boiler wall and inside the boiler itself. The outboard end wall 116 positioned apart from the boiler wall comprises an opening 119, which enables various specific portions of a sootblower 10 to be accessed from behind when the carriage 18 is retracted, As a result, it is possible to access the carriage and the lance tube from above and below. |
