1.1 This test method covers the determination of the fineness by sieve analysis of coal sampled from a dry pulverizing operation. It is not applicable to products of wet milling or to fines that have clustered into an agglomerated mass.
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.
Finessing fuel fineness Most of today's operating coal plants began service at least a generation ago and were designed to burn eastern bituminous coal. A switch to Powder River Basin coal can stress those plants' boiler systems, especially the pulverizers, beyond their design limits and cause no end of operational and maintenance problems.
