Abstract
Self-heating of coal promotes spontaneous combustion during mining, transportation, storage, handling and milling processes leading to risk of fires and consequent loss of calorific value of fuel. Adiabatic oxidation method was adopted in this investigation whereby spontaneous heating potential was measured according to total temperature rise (TTR) of coal sample versus time. Aim of this study was to investigate correlation of intrinsic properties of coal and its propensity for spontaneous combustion. Tests were conducted on 14 coal samples at an initial temperature of 40 ℃ to mimic typical conditions in coal storage and handling plant. A correlation of the TTR values with the proximate and ultimate analyses of the coal samples has been obtained.
