Physical Modeling of Forest Fuel Ignition by the Molten Metal Particles

Forests in the Siberian region have suffered from frequent and intense forest fires in recent years. Measures are required to restore damaged and dead forest stands. One option for preserving forest stands from catastrophic forest fires is prescribed low-intensity burning. The purpose of the study is to study the ignition mechanism of a layer of forest fuels by crystallizing small-sized metal particles (molten metal drop). The generation of such droplets is carried out using a standard electric welding machine. The physical mechanism of forest fuel layer ignition by a group of particles of a rather small size is revealed. It is proposed to use this mechanism for burning forest fuels in order to preserve coniferous and mixed stands from intense forest fires.
