Studying the Swirling Effect on the Thermal and Combustion Characteristics for the Gas Domestic Burner

Abstract

An experimental study carried out, to investigate the thermal efficiency and carbon monoxide emissions for different gas domestic burner designs, these designs included a number of approaches that were determined to influence of these aspects on the overall performance of the burner. In this research, two types of burner were examined a single ring burner and a double ring burner. Testing each burner on multiple pan support heights at different air to fuel ratios to see the tangible enhancement. For the single ring burner three burners were tested a radial ordinary design, a swirl design and an impinging flames design. The highest efficiency was for the swirl single ring, and the achieved efficiency was 60.4% with a rise of 1.5% from the radial design at the lowest pan support height and highest Reynolds number.
