Description
Summary:This paper reports on the performance of a prototype natural gas-fired cooktop burner which was developed for lower NO 2 emissions and improved thermal efficiency. A circular ring insert was part of the prototype burner. It was made from 6 mm stainless steel rod and placed at the side of the burner slightly below the ports. The prototype burner had a 42% lower NO 2 emission per unit useful energy compared to a commercially available burner at 3.3 kW. The relative improvement in thermal efficiency was 19%. The prototype burner was tested over the full range of thermal input, from 3.3 kW down to 0.66 kW. The insert did not cause any problem for emissions or efficiency at any thermal input within the range, provided it was appropriately located relative to the burner ports. As the burner was turned down, the NO 2 emission decreased and thermal efficiency increased, as normally observed with gas cooktop burners.
