Abstract : The effect of the air excess factor and the rate of gas flow on electrical conductivity in methane-air flames were investigated. The experimental setup is shown. The maximum electrical conductivity of the flame falls within alpha = 0.8-1.0; alpha is the air excess coefficient. It was found that the magnitude and distribution of electrical conductivity in the flame depends upon the flow rate of the combustible gas mixture. An increase in the flow rate of air-rich mixtures results in higher maximum electrical flame conductivity while the reverse is true for air-lean mixtures. The dependence of the magnitude of the maximum electrical current upon alpha is shown. The dependence of the maximum current along the flame axis upon gas mixture flow rate at various alpha's and electron current between the rate at various air excess coefficients are graphed.
