Abstract
The flame and emission characteristics of a premixed gaseous flame swirl burner are investigated under various equivalence ratio. The swirl flame is established using propane/air mixture at atmospheric condition. Flame imaging was performed to compare the global flame shape and intensity over a range of equivalence ratios and flow rates. Fuel-rich flame shows increased intensity due to the presence of soot formation. The lean blowout test was performed to determine the operating limit of the burner. Emissions of the propane swirl flame were measured at the exit of the burner outlet. Results show that NOx emissions peak at stoichiometric condition, ϕ =1 as compared to the lean- and rich-burning regions. Carbon monoxide (CO) and unburned hydrocarbons (UHC) emissions were found to be low ( 10 ppm) under premixed, continuous swirl burning conditions for the equivalence ratio range of ϕ = 0.7-1.1.
