The Effect of Different Swirling Flow Patterns on the Performanceof a Domestic Single Ring Burner
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 5
Abstract
In this research, we studied the swirling effect on a single ring gas domestic burner were the testing was performed on3 patterns of flow orientation: Swirl flow and Star pattern swirl and the radialflow as a Benchmarking burner.The influence of the pan height to the flame frontand Reynolds number has been introduced as the changing conditions. To study the improvement of future domestic gas burners by increasing thethermal efficiency as well as decreasing CO emissions, LPG was used as the testing gas for the examination of these burners. The results indicated that, usingthe swirl motion improved the thermal efficiency and CO emissions, but for the Star pattern burner the CO emissions improved evidently.Increasing the pot heightfrom the burnerfront flame 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 Swirl flow burner, the efficiency increased by 2.7% from the benchmarked burner. On the other hand, the CO emission decreased by 80% for the star pattern burner from the benchmark due to two reasons increased first the gaps between each flame length which allowed more air to reach the flames and help complete the combustion process secondly the increased flame length because of impinging flames increased the inertia of the flow which resulted into propagation in the radial dimension decreasing the contact with the heated load.
