Ignition Temperature of Coal. 5. Practical Applications

If the ignition temperature tig of the unoxidized coal determined in accordance with Ukrainian State Standard DSTU 7611:2014 is used to check the rank assignment of coal concentrates supplied to the coke plant, inconsistency of the actual and declared ranks of the coal may be identified in timely fashion, the properties of the coal may be preliminarily studied, and the results may be used in adopting measures to maintain the specified rank composition and properties of the coal

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.
