The paper reflects the influence of various factors on the height of the flame of solid combustible substances and materials, as well as the need to develop a method for determining this geometric parameter. Existing combustion methods for determining the geometric parameters of fires objectively reflect only the combustion process of combustible gases and liquids, since the height of the flame of such fires depends on the characteristic size of the fire source and the rate of entry of the combustible component in the reaction zone of combustion, which remain relatively constant over a long time. Combustion process of solid substances and materials is more complex and multi-faceted, so that the specific mass burn-up rate, and, accordingly, the height of the flame of such substances are not constant and depend on many additional factors.
