Kinetic parameters of ignition are defined by the results of performed experimental and theoretical investigations of regularities of the process ignition dispersed solid condensed substance when interacting with a high-temperature metal particles.

Abstract.The results of an experimental investigation of ignition liquid fuel (kerosene, diesel fuel) by the single drops under conditions of radiation-conducting heating in air are presented. The dependences of the ignition delay time of the typical fuels droplets on the initial temperature of the heated oxidant in a limited space are established. The parameters of stable ignition of liquid fuel droplets are set.

Abstract. The methodology and results of an experimental study sets out the law ignition of typical liquid fuel -mazut, single heated up to high temperatures metal particles and porous particles of the metal oxides. The installed dependences of the numerical values of the ignition delay times of the temperature of porous particles (obtained after the welding) steel and solid particles of regular shape. The showed influence of the shape and structure of the particles (solid and porous) on the regularity of the process of mazut ignition.
