The article presents a method of explosion protection of drying installations of dispersed materials, which consists in using equipment capable of withstanding the full explosion pressure of a combustible mixture. It discloses a method for reducing the maximum pressure of an explosion by reducing the size of drying units is considered. The process of extinguishing the flame in narrow channels. The article considers in detail the conditions for the exchange of radiation energy between bodies and the estimation of heat loss by radiative flame exchange in a closed volume. It also obtains an expression for determining the pressure of an explosion in a closed volume with allowance for heat losses.
