International Classification:

F27B 902

US Classification:

432128

Abstract:

An oven construction in which an elongated oven assembly is provided by manufacturing a plurality of oven modules at a factory location and then shipping the modules to the usage site where they are assembled together in end-to-end fashion to form the final oven assembly. Each oven module includes an outer shell and an inner shell mounted so as to be spaced apart for insulation therebetween. The shells are interconnected at one point along the length thereof, but are allowed to expand differentially along the remainder of their lengths. The outer shell is rigidly tied to a foundation but the inner shell, through any of various approaches, is allowed to slide or move relative to the foundation everywhere except the one point where it is secured to the outer shell. Each module has a bellows-type expansion joint around the periphery of one end to allow for interconnection of the modules, one to another.
