ABSTRACT:
A burner entry block constructed of an assembly of a plurality of parallel layers of ceramic fiber insulation bound together with thin layers of refractory mortar sandwiched between adjacent layers, the assembly of such parallel layers forming a generally rectilinear solid assembly, having ceramic fiber layers transversing from front to back of the block and being secured to a mounting plate at their front. Said multi-layered assembly defining a transverse, front-to-back, centrally-located opening, which opening is sized to receive the output of a gas burner positioned at its front. The plate has means for securing the block to a ladle cover or like insulating cover. The block is constructed by the method of successively laying down rectilinear mats into a form made of the back plate, side walls and a bottom wall, securing the ceramic fiber mat to the mounting plate, applying a layer of refractory mortar to the surface of one side of the mat, pressing another layer of mat into the mortar while the mortar is still wet, and repeating the steps with a new mat so as to bind successive mats together by the mortar, and, when the entire assembly is completed, securing a top wall to surround the assembly on all of its sides and cutting out a hole for the burner by slicing through the assembled layers of sandwiched mats from front to back to form the burner output receiving opening therein.
