• Description:
  The US Bureau of Mines has found a combined parameter, called the moist fuel ratio, based on the proximate analyses of coals which appears to be highly correlated with both the spontaneous combustion and dust-producing characteristics of coals. It appears quite remarkable that the moist fuel ratio is successful in modelling both physical breakage mechanisms and chemical behaviours of coals which range from lignite to low volatile bituminous coals from the United States, Turkey and Australia, as well as three totally independent sets of data. Although it is generally known that self-heating and spontaneous combustion of coal is a function of coal rank along with other factors such as oxygen concentration, temperature, moisture and ventilation, an explanation for moist fuel ratio significance is not known. These correlations suggest that a fundamental relationship may exist between the physical and chemical characteristics of coals and that some fundamental importance may be associated with the moist fuel ratio.
