Key Points

  • The aim is to analyze how demineralisation affects the ignition properties of brown coal using laser pulses.
  • Investigated ignition of brown coal samples with 1-10 ms laser pulses.
  • Used a quasi-continuous ytterbium laser YLR-150/1500-QCW-MM-AC at 1070 nm and 1.6 kW.
  • Compared energy requirements for ignition before and after demineralisation.
  • Demineralisation increases the energy density needed for ignition.
  • There is a measurable difference in ignition thresholds before and after demineralisation.

Abstract

Laser ignition of brown coal samples (rank 2B, Kaychaksky open pit) with rectangular 1-10 ms pulses of the quasi-continuous ytterbium laser YLR-150/1500-QCW-MM-AC (1070 nm, 1.6 kW) has been investigated before and after coal demineralisation. Coal demineralisation is demonstrated to cause an increase in the energy density necessary for ignition.
