As part of an ongoing effort to improve emissions and increase efficiency of natural gas fired turbines, this work was undertaken to determine if electrical impedance measurements of the flame are a direct indication of fuel/air ratio. Previous worked measured electrical resistance of the combustion of gases in an atmospheric combustor. From this work, it was conjectured that the complex impedance might provide more information about the flame than using pure resistance. This thesis discusses the measurement of the complex electrical impedance of a Methane Flat Flame Burner. The data shows a relationship between the magnitude of the impedance and temperature, which relates directly to the fuel/air mixture. This work was supported in part by the National Energy Technology Laboratory (NETL).
