A minimum airtocoal weight ratio of :1 is desired at full load. The ratio could be higher at lower loads (more air per pound of coal). Failure to provide adequate airflow through the mill can result in spillage of coal. The exhauster discharge pressure is an indicator of flow and velocity through the coal piping.

Description Pulverization of coal is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.
