Apparatus for lining furnace walls

摘要

A method of lining the hot face of the wall of a heated enclosure, such as a furnace, boiler or the like, comprising the steps of compressing a plurality of substantially cylindrical modules of ceramic fiber material inwardly from the perimeter thereof; attaching the individual, compressed modules to the hot face of the wall in predetermined relationship whereby to define certain openings therebetween, inspecting the attaching means by virtue of the access thereto provided by the openings; filling the openings with a plug of ceramic fiber material; and then releasing the compression upon the modules to permit radial expansion thereof in all directions whereby to create a lining over the entire wall. The apparatus to achieve the method consists of a plurality of initially compressed modules of ceramic fiber material; means for attaching the compressed modules to the wall, in the form of a stud welded to the wall, a bracket carried by the stud and legs on the bracket which receive and hold a rod extending through each of the modules; there being means for retaining the modules in their initially compressed condition in the form of a casing which is octagonal in configuration and is placed over the module when it is initially compressed, the casing being removed after the module has been placed on the wall, the attaching means inspected and the openings filled by the plug of material whereby the modules each expand radially outwardly to cooperate with the plugs to line the wall.
