significance of coal mill fineness:

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.

Pulverizer Fineness

The adverse effects are compounded because burners having more coal will likely be of lower fineness making it even more difficult to achieve complete combustion in the burner belt zone. Importance of Fineness. Poor Coal Fineness often yields poor distribution as large coal particles air mix to form a (2) phase mixture which will not homogenize.
