Read MoreImpact of Pulverizer Performance on Ash L.O.I. Higher than desired flyash or bottom ash Loss on Ignition (LOI) or unburned Carbon content is frequently caused by less than optimum coal fineness. The graph below illustrates a typical relationship between flyash LOI and coal fineness on a tangentially fired boiler firing Eastern Bituminous coal.
