Abstract

The article is devoted to the problem of studying the electrical properties of a flame in a fire. The article discusses a method for measuring the active electrical resistance of a diffusion flame when burning liquid combustible substances. The dependence of the electrical resistance of the flame torch on the geometric dimensions of the combustion zone and on the average volumetric temperature of the flame torch in the mode of the laminar flow of the combustible mixture has been established. An empirical dependence has been obtained, which makes it possible to calculate the value of the electrical resistance of the flame.
