| Abstract | ||||
| The present work aims to clarify the stability limits and thermal combustion characteristics of a dual swirl vanes co-axial burner. The investigated burner consists of eight gaseous jets arranged in two consecutively interacted equal lotus bundles in the axial direction downstream of the flow. These eight jets can be easily moved and directed to penetrate the combustion reaction zone at different axial positions with four inclination angles at the burner axis (θ= 0°, 30°, 45°, and 60°). This axial motion is easily performed by adjusting few screws mounted on the burner which facilitate the jet interaction inside the surrounded combustion air between the liquid and gas fuels which consumed by the dual burner. At different jet injection positions and jet inclination angles, stability loop, temperature, and regulated gas emissions such as nitrogen oxides, carbon monoxide and unburned hydrocarbons are measured. The location of interaction has an influence on the pollutant emissions and temperature as well as the combustion efficiency. This influence will be clearly demonstrated to reach the optimum design configuration. | ||||
