Abstract
The results of an experimental study of laws governing the ignition of liquid propellants (kerosene, diesel fuel and petroleum residue) by the single spherical steel particle heated to high temperatures are presented. Is carried out the comparison of the ignition delay times of the investigated flammable substances by the particles in the sphere and disk forms. It is established that the particle shape does not exert a substantial influence on the ignition process characteristics.
Highlights
As a result of experimental studies [1,2,3] found that the high temperature of the particle in the form of a disk are sustainable sources of ignition typical liquid fuels at temperatures above 1230 K

Investigated experimentally the ignition group of typical liquid fuels single heated to a high temperature metal particles in the shape of a sphere and a disk
Summary
As a result of experimental studies [1,2,3] found that the high temperature of the particle in the form of a disk are sustainable sources of ignition typical liquid fuels (kerosene, diesel fuel, fuel oil) at temperatures above 1230 K. In practice, the heated particles are spherical, so it is reasonable to study the ignition of liquid fuel particles in the form of a sphere. This will determine the degree of influence of particle shape on the parameters of the ignition. The purpose of work – experimental study of fire ignition fuels single heated to a high temperature steel particle in the form of a sphere and the data obtained are compared with the results of similar studies for particles in the form of a disk
