The fineness of themillingproduct and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate ofcoalin themill, coalretention time and the flow resistance. As a result, the maximummillcapacity decreases and the rate of change of operational parameters of the furnace system deteriorates. In extreme cases, the performance of theboilermay be limited, and therefore improving the fineness ofmilling…

Pulverizedcoalfiredboilersthe total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses inboilerthat can be tuned by operator are carbon loss and dry gas loss.

Pulverizers (coal pulverizer) are used to pulverize pieces ofcoalinto fine particles (100μm) before placing into aboiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification.
