Physical Modeling of Forest Fuel Ignition by the Heated Up to High Temperatures Particle

Abstract

This chapter discusses a comparative analysis of the results of physical modeling of ignition of various forest fuels by a particle of metals and nonmetals heated to high temperatures. Typical forest fuels are considered: pine litter, birch leaves, and grass. The results of physical modeling of ignition of spruce branches with needles are discussed separately. Conclusions are drawn about the lower limit of ignition and fire danger of particles heated to high temperatures. The physical mechanism of ignition of forest fuels by a particle heated to high temperatures is presented.
