Abstract
The measured thresholds (H cr) and kinetic characteristics of the ignition of the volatile substances and the coke residue of low-rank coal under the action of the pulses of a neodymium laser (1064 nm, 120 μs) are reported here. The ignition of volatile substances was observed in microsecond (H cr = 0.3 J/cm2) and millisecond time intervals (H cr = 1.2 J/cm2). The combustion of the coke residue occurred in a time interval of 30–100 ms (H cr = 2.6 J/cm2).
