Abstract
Methods and systems for constructing a refractory wall structure having gas flue spaces are provided. In certain embodiments, a first course of the wall structure may be constructed by installing opposing refractory side wall panels that are separated by a distance which defines a widthwise dimension of the wall structure and an interior wall space therebetween. The side wall panels may include multiple sets of finger forms defining a joint space (e.g., a dovetail joint space), whereby the finger forms protrude inwardly into the interior wall space such that the sets of finger forms of one side panel are oppositely positioned relative to the sets of finger forms of an opposed side wall panel. Thereafter, a series of rigid refractory bridge components may be installed between respective oppositely positioned sets of the finger forms of the opposed wall panels so that a portion of the refractory bridge components is received with the joint space of the finger forms to thereby establish the flue spaces between longitudinally adjacent ones of the bridge components.
