Heat and Mass Transfer in Quenching the Reaction of Thermal Decomposition of a Forest Combustible Material with a Group of Water Drops

Abstract

We have carried out computational investigations of the processes of heat and mass transfer in quenching the reaction of thermal decomposition of the typical forest combustible materials (birch leaves and pine and fir needles) with a group of water drops. It has been established that the termination time of pyrolysis is influenced by the integral parameter characterizing the relative position of drops and the temperature of the vapor-gas mixture over the forest combustible material. The thicknesses of layers providing termination of pyrolysis of evaporated liquid materials for a group of drops have been determined.
