  • Pulverizer Fineness

    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. Good Fineness Creates a homogenous & balanced mixture which behaves more like a gas than a (2) phase mixture of air & fuel Common Issues Boiler Slagging Pulverizer Fire and ExplosionsCoal 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.
