Dynamic Modelling and Simulation of Coal Pulverizer

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].

Pulverizer Optimization Components - Storm

The important elements of pulverizer performance are fineness, fuel distribution, coal (pyrites) rejects, and primary airflow calibrations. Optimizing pulverizer performance is a prerequisite for optimum furnace combustion. About three-fourths of the 13 Essentials are pulverizer, primary air, and fuel line related.
