A segmented radiant burner assembly for installation in the combustion chambers of firetube boilers and the like. The individual segments can be assembled together for on-site installation within the boiler. The segments include support structures comprising mounting flanges which are secured together in series to form the burner assembly. Gas and thermal sealing between the active material of the burner and the inactive support structure is provided by a sealing system which includes a dense fiber composition material and adhesive agent of ceramic composition. The mixture of unburned reactants is directed through a valving and manifold system into separate plena within the burner segments. The flow rates of reactants to the different burner segments is selectively controlled in a sequence which achieves a broad firing rate range.
A radiant burner assembly for installation in a combustion chamber comprising the combination of a plurality of burner segments, each segment including an active burner wall of porous fiber composition for supporting surface combustion of reactants and a support structure comprised of a material which is inactive for combustion, said wall joined with said support structure along an interface to at least partially enclose a plenum for the unburned reactants, sealing means extending along the interface and adhering therealong to the surfaces of the wall and support structure to seal the interface, securing means for joining together in abutting relationship the facing portions of the support structures of adjacent segments to form a unitary burner assembly, and means forming flow channels for serially directing an inlet stream of unburned reatants from one end of the assembly into the plena of the segments, said flow channels being openings formed in the facing portions of the support structures for communicating respective plena of adjacent segments.
