The design of their storage, handling, preparation, and firing systems needs to be aligned to their properties. The most important aspect is that the fuel input has to be uniform, and its metering has to be reliable. Processing of coal and petcoke is done by grinding them to a specific fineness in ball mills, vertical roller mills, or impact mills.

Since one kilogram (or pound) coal requires approximately kg (or !b) air for combustion, the fueVair mixture emanating from the coal mill must be kept well below this critical ratio to prevent premature ignition. Most coal mills operate at air/fuel ratios that are less than kg (lb) per kg (lb) of coal.
