Experiments with an inshot burner used in residential natural gas furnaces are presented. The concentrations of NO{sub x}, NO, and CO in the combustion products of partially aerated natural gas flames were measured in a laboratory combustion chamber. When the conventional circular venturi inlet of the inshot burner was replaced by elliptic venturi inlets, an increase of up to 30% in the primary-air entrainment and a decrease of up to 20% in the NO{sub x} emission index were observed. Temperature field measurements in the flames were in conformity with the emission index measurements.
