ABSTRACT:
An apparatus and method for use in a combustion system of a gas-fired furnace to inhibit formation of oxides of nitrogen (NO.sub.x) by the combustion system thereby reducing NO.sub.x emissions from the combustion system. The apparatus is made of a material which is positioned at the interface of the primary zone and the secondary zone of a combustion flame produced by a two-zone burner which is part of the combustion system, to temper the combustion flame by absorbing thermal energy from the combustion flame. The device sufficiently tempers the combustion flame to limit peak combustion flame temperatures and residence times at these peak combustion flame temperatures to levels which inhibit formation of oxides of nitrogen.
