Low temperature heating and oxidation to prevent spontaneous combustion using Powder River Basin coal

Powder River Basin coal, a subbituminous coal, was studied for its low temperature oxidation tendency after a simple surface oxidation treatment. The influence of the heating temperature on the coal properties was studied. The tendency of this dried coal to oxidize at low temperatures was successful...
