Flame characteristics analysis of a methane gas’ premixed combustion on a ring attached-bunsen burner using ansys fluent

Abstract Many studies have had been done relating to the Bunsen burner. However there are only a handful of studies which focus on the implementation of a foreign component integrated to a Bunsen burner. Therefore, the effect of such component to the Bunsen burner still need to be investigated further. The study proposes a further analysis on the effects of a ring, primarily its temperature, on the Bunsen burner to the flame characteristic of methane gas. Flame’s temperature, flame’s height, and laminar flame speed are the 3 key properties observed. The study is done using a computer based numerical simulation software Ansys, implementing a 2D Fluent steady state analysis. The variations are the value of the ring’s temperature, which are 400 K, 600 K, and 800 K. The result of the study suggests that for the same equivalence ratio value, the higher the temperature of the ring attached to the burner, resulting in a higher flame’s temperature and laminar flame speed value. Proven by the fact that the 800 K temperature variation has the highest value of both flame’s temperature and laminar flame speed for the same value in equivalence ratio compared to all of the variations. However, a higher ring’s temperature value resulting in a lower or reduced flame’s height formed for the same equivalence ratio. Also proven by the fact that the 800 K temperature variation also has the lowest flame’s height value compared to all the variations at any given equivalence ratios.
