MEASURING PRIMARY AIRFLOW

The main functions of primary air are to dry the coal and then pneumatically convey the pulverized coal from the mill to the individual burners Primary air also determines coal particle velocity at the burner exit, in part , Coal mass flow and particle velocity data from a Pf-FLO coal flow.
