Abstract
The swirling effect on the gas hob of double ring domestic LPG burner was investigated using 4 patterns of swirl orientation: Co swirl, Counter swirl, Star pattern swirl and, the radial flow as a Benchmarking cooker burner. To improve future domestic gas burners thermal efficiency and CO emissions of these burners are compared using LPG. The influence of Reynolds number and the pan height above the flame (as normalized by the Burner outer diameter) has been studied. The results showed that using swirl motion increased both the thermal efficiency and CO emissions, except for the Star pattern burner whereby the thermal efficiency increased while the CO emissions decreased. Increasing the pan height to the burner outer diameter decreased the thermal efficiency and CO emissions under all operating conditions due to lower pigmentation of the flame to the pan bottom which reduces the heat transfer from the flames to the heated pan. For the counter flow burner, the efficiency increased by 2.1% from the radial one while it increased by 1.7% and 0.9 % for the co swirl and star pattern respectively. On the other hand, the CO emission decreased by 33% for the star pattern burner from the benchmark one.
