This study evaluated the spontaneous combustion characteristics of Askale lignite from Turkey. The effect of the gas flow rate, the moisture of the piles of coal, the humidity of the air and particle size on the spontaneous combustion characteristics of coal samples were examined using Crossing Point Methods adapted to our laboratories conditions. The amounts of three predominant oxygen functional groups (carboxyl, hydroxyl and carbonyl) in untreated and moist coal samples were also determined with wet chemical methods. The amounts of oxygen functional groups in moist coal samples do not differ significantly from that of untreated coal. The liability of spontaneous combustion of this lignite was increased with decreasing particle size, increasing moisture content of the coal and decreasing humidity of the air. © 2003 The Combustion Institute.
