Abstract:
This paper presents the results of a study of the ignition of nine brands of coal from the Kuznetsk Basin by laser pulses (120 $\mu$s and 1064 nm). Depending on the laser pulse energy density, three types of processes can be distinguished in the general process of coal ignition, and they differ in threshold, temporal, and spectral-kinetic characteristics. The first type is associated with flame ignition on the surface of coal particles, and the second and third types are related to the initiation of various thermochemical reactions within particles. The laser pulse energy density defines the intensity and duration of the flame glow, as well as the flame column height.
Keywords:
