This article describes an investigation of combustion characteristics with various compositions of synthetic natural gas (SNG) in dual swirl combustor. The objective of this study is to investigate the flame stabilization, flame structure, fuel compatibility in SNG flame with varying fuel compositions. As experimental conditions, hydrogen content was adjusted from 0 to 11%. Moreover, addition of hydrogen enables keeping stable combustion condition when, for the same methane flow, the flame becomes lifted and very unstable. Experimental results show that the addition of hydrogen has a major effect on flame behavior due to the higher burning rates associated with hydrogen consequently, The higher reaction activity of hydrogen has increased the unstable or flashback region. However, stable flame region was shifted to the lean condition.
