We have found that targeting an A/F ratio around lb of air per lb of fuel is best. For some pulverizer types, such as ball tube mills and highspeed attrition mills, often a A/F ratio is optimum. Never have we observed good combustion conditions or good mill performance with A/F ratios of or greater.
Coal preparation is an important aspect of coal handling. When coal leaves a plant''s coal handling system, it generally is sent to one of two places. Depending on the design of the plant, the coal may go directly to a boiler furnace to be burned, or it may go through coal processing equipment, such as a pulverizer, before it is burned.

Many coal pulverizer designs do not incorporate any filtration in their lube circuits. The pulverizers that do not incorporate filtration use coarse filtration such as 40micron cleanable mesh or 200micron cleanable, stacked disk filters. Such OEMsupplied filtration is often unable to keep up with the inherently high ingression rate.
