Mechanical, thermophysical and aerothermochemical processes at forest fuel ignition caused by the heated to high temperatures single metal particle

Research output: Contribution to journalArticle

Abstract

The particles of metals and nonmetals heated up to high temperatures are the most common sources of the human-caused ignitions. As a rule, metal particles are formed as a result of welding and cutting metals, as well as a result of accidents at industrial facilities. Metal particles, namely steel particles, are considered in this paper. The experimental installation is equipped with a high-speed camera for capturing the processes of particle interaction with a typical forest fuel (dead grass) and its ignition. A compact tube furnace was used as a heater. The main regularities that characterize a complex of mechanical, thermophysical and aerothermochemical processes are revealed during ignition of a typical forest fuel. The ignition conditions and the ignition delays of the forest fuel by the heated to high temperatures particle are established. Conclusions are presented about fire danger of the particles heated to high temperature. Recommendations are proposed for the development of physical and mathematical models to simulate forest fuel ignition by the heated to high temperatures single particle.
