<p>GAS-FIRED RADIANT BURNER A radiant gas-fired burner having a back plate for connection to a supply of air and gas which, together with a combined refractory fiber pad-metal support structure, defines a plenum for supply of a combustible air-gas mixture. A foraminous metallic member is embedded within a porous pad of refractory fibers and interlocked therewith. Lugs affixed to the rear surface of the metallic member afford connection to said back plate in a manner allowing easy detachment therefrom without dismounting said back plate from its operative position. The burner has a rectangular surface that is uniformly radiant which was formed by vacuum-forming a refractory fiber felt onto the foraminous member. Metal foil around the periphery of the pad prevents gas flow from escaping through the side edge.</p> |
