Friability and previous oxidation of the coal are also important factors in the self-heating (spontaneous combustion) process. Directional properties also occur in coal and these properties can affect the direction of flow of gases. Furthermore, discontinuities in the coal structure give a wide sample-to-sample variation.
The importance of the coal blend properties as a factor in coke gasification has also been reported [16], [17]. Cokemaking conditions, for example, bulk density, coking time, preheating of the charge, etc., minimize some deficiencies in coal properties. ... The Coal Handbook, 2023, pp. 587-625. Lu.

Coking coal is best if it has a very narrow range of volatility and plasticity. This is measured by the free swelling index test. Volatile content and swelling index are used to select coals for coke blending as well. Volatility is also critical for steel-making and power generation, as this determines the burn rate of the coal.
