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.
