Abstract

This paper presents the results of experimental studies of the ignition of a typical vegetable combustible material (dry grass) by a single particle heated to high temperatures. The ignition conditions correspond to the rather typical conditions of the action on a vegetable combustible. The dependence of the ignition delay time of dry grass on the initial temperature of the particle has been obtained, and the limiting temperatures of combustion initiation have been determined. A hypothesis on the mechanism of heat transfer in a heated bed of the material during the induction period has been formulated.
