A flame radiator structure is disclosed for inhibiting formation of oxides of nitrogen (NOx) by a combustion system of the type having at least one monoport inshot burner which burns fuel to produce a combustion flame which is projected through an inlet opening into a heat exchanger for the combustion system. The flame radiator structure comprises a perforated, tubular, main body section having open ends and means for attaching this perforated tubular main body section at the inlet to the heat exchanger. Alternating ribs and oblong openings are spaced along side walls of the perforated main body section to stiffen the structure and to allow the structure to safely expand and contract in response to thermal cycling. The flame radiator structure is sized, configured, and positioned relative to the combustion flame produced by the monoport inshot burner to temper the flame by absorbing thermal energy from the combustion flame at a rate which limits peak flame temperatures and residence times at these peak flame temperatures to levels which inhibit formation of NCx while allowing substantially complete combustion of the fuel supplied to the burner.
