Influence on Mill Performance on Combustion and Boiler Performance
Milling performance is critical in controlling the combustion process in the boiler.
Coal pf fineness influences:
- ignition delay;
- combustion efficiency;
- particle erosion;
- loss on ignition (and hence coal costs);
- value of ash and ability to dispose / sell;
- emission levels;
- boiler slagging and fouling;
- potential damage to superheater tubes from combustion delay.
