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 process of coal blending coking and the interaction mechanism are comprehensively studied and determined. During the coking of blends with two kinds of coal, the first pyrolysis is followed by the release of volatile matter and the formation of a plastic layer. The release behaviour of volatiles is first affected by the composition ...

Coal blending is a process of uniformly combining two or more kinds of coking coal in appropriate proportions to obtain the required blended coal. It is a …
Coke is an important raw material in the steel industry, and its quality directly influences the smelting of iron and steel. To improve coal quality and reduce coal blending costs, we need to predict the coke quality and optimize the coal blending scheme. In this paper, we propose a modeling and optimization method based on the characteristics of …
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.
