Physical Modeling of Forest Fuel Ignition by the Focused Sunlight

Abstract

This chapter discusses the issue of experimental modeling of the forest fuel layer ignition by the focused solar radiation. The main types of glass containers that can be found in forested areas are considered. Two experimental facilities are presented for simulating smoldering and ignition of forest fuels under the influence of focused solar radiation. Samples of forest fuels typical for the Siberian regions (Tomsk region and Republic of Buryatia) are investigated. Data on the physical mechanism and ignition delay of forest fuel are presented.
