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.

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 ...
