Abstract
In a fuel gas burner, a reduction of NO emissions is brought about by the combined use of both a catalyst and a radiation baffle. The catalyst and baffle are located in serial flow relationship such that each contributes to the NO reduction function without the creation of undesirable conditions. The catalyst is located upstream of the flame and the amount of primary air supplied to the burner is controlled so as to bring about a reduction of NO emissions while at the same time not allowing the temperature of the catalyst to exceed a threshold limit, thereby ensuring an acceptably long life and durability of the catalyst. The radiation baffle is located in the flame to radiate heat away therefrom and lower the temperature thereof to reduce NO emissions, with the mass of the baffle being limited such that no significant levels of CO are generated.
