A SUMMARY OF EXPERIENCES RELATED TO

2013-11-27 · Coal Fineness and Fuel Balance • As fineness increases (reduction in coal particle sizing), fuel balance improves. The finer the coal, the more the two- phase mixture (coal and air) behaves like a fluid than a solid in suspension. • The more homogenous mixture of air and coal results in more even distribution between the separate burner ...
