A low NOx combustion process and burner apparatus in which a mixture of a primary fuel and air, with the air in excess of the stoichiometric requirement, is passed to a surface burner element. The mixture is distributed over the downstream side of the element where it is combusted in a primary combustion zone. Secondary fuel is mixed with surface combustion products from the primary zone and then combusted in a secondary combustion zone with a portion of excess oxygen from the surface combustion products. In certain embodiments the temperature of surface...
[ What is claimed is:] [1.] A combustion process for controlling NOx emissions, comprising: passing a mixture of primary fuel and air, in which the mixture has an excess portion of air which exceeds the stoichiometric requirement, to a surface burner element, distributing the mixture over the downstream side of the surface burner element, combusting the mixture on said downstream side in a primary combustion zone to produce surface combustion products and heat together with the excess portion of air, mixing secondary fuel with the surface combustion prod...
