چکیده انگلیسی
Samples from New Zealand and Australia have been tested in an adiabatic oven to assess the effect of rank on the R70 self-heating rate of coal. A non-linear relationship can be defined for coals from both countries using the revised Suggate rank (Sr) parameter. Subbituminous coals have the highest R70 self-heating rate values, which are 20 times that of high volatile A bituminous coals on a dry mineral matter free basis (â¼Â 1 cf. 20 °C hâ 1). However, the moderating effects of moisture and mineral matter can reduce this difference to only 2-3 times for coal in-situ.
