Abstract
An industrial furnace with insulating walls comprising side-by-side pre-formed panels each including a plurality of ceramic insulating modules. The side wall panels include vertical buckstays to which the modules are secured by retainer clips including sharp spikes inserted into side edge surfaces of the insulating modules. Modules with offset stepped side profiles are disclosed, arranged to provide for ready removal of a single module without disturbing adjacent modules. Atmosphere furnace insulation arrangements also are disclosed utilizing ceramic modules secured to the furnace shell by special retainer clips embedded in side edge surfaces of the modules.
Claims8
An industrial furnace used for material heat treatment and the like, comprising:
- a plurality of ceramic fiber insulating modules positioned side-by-side;
- each of said modules including an inner section presenting a face to the interior of the furnace;
- the side edges of said inner module sections being mated together in close proximity to establish an effectively continuous insulation area;
- each of said modules further including outer sections integral with said inner sections but having smaller lateral dimensions to form set-back side edges;
- flexible and compressible insulating material in the regions between adjacent set-back edges and at least substantially filling the spaces of said regions;
- and
- support means securing said modules in position.
