Ignition temperature of coal. 2. Binary coal mixtures
The ignition temperature of binary coal mixtures is determined. The mixtures contain coal of different metamorphic development, in various proportions. Systematic deviation of the actual ignition temperature from the values calculated on the basis of the sum rule is observed; the actual ignition temperature is lower. Statistical analysis shows that these deviations are significantly nonrandom.
