pulverizer. The major measurement parameters of coal pulverizers are typically pulverizer outlet temperature, coal mass flow, primary air flow, inlet primary air temperature, motor current and pulverizer differential pressure at various MW load. Earlier works on derivation and validation of a coal pulverizer model for control has been done [1 4].

The function of a modern pulverizer system is to dry and grind the power station's coal supply and distribute it to the burners. In a bowlmill coal pulverizer, raw coal, which is fed through a central coal pipe at the top of coal pulverizer, falls by gravity to a rotating grinding table where it is pulverized between grinding rollers.
