Coal Pulverizers an overview | ScienceDirect Topics

The moisture content has a major impact on pulverizer performance Increasing coal moisture (ie, lower quality fuel) content can impact unit capacity if the primary air supply system cannot provide air at a high enough temperature The air/coal ratio can be increased to provide more heat for drying; however, this in turn affects classifier operation, burner performance, pulverized coalpulverizer 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 [1Dynamic Modelling and Simulation of Coal PulverizerMajor CoalUnique Components Coal Pulverizers For PC units, coal is fed into a pulverizer to be ground into a fine powder to facilitate combustion Pulverizers are approximately 30 feet high and are fabricated mostly from steel and steel components Several independent pulverizers are typically installed to accommodate firing and reliability requirements for an EGU Pulverizers use metal crushCHAPTER THREE CoalFired Power Plant Designs,
