2019-2-15  Some of the most important factors which heighten the danger of self-ignition of coal are: High volatile content in the fuel (>20 % over dry) The more fine-granular the coal, the larger the reactive surface to absorb oxygen (proportion of fines greater than 10%) Coal containing, besides the fine-granular portion, also coarse material, since air

Coal Mill an overview ScienceDirect Topics

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

ACARP Abstract

The main operating costs, other than coal costs, are related to the milling and distribution of the coal to the blast furnace. LV coals, compared to HV coals, are generally softer and thus require less energy to grind, but they require a higher energy to dry the coal down to a moisture level required to eliminate the risk of handling problems.
