Coal Mill - an overview ScienceDirect Topics

The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from 1.75 to 2.2 with a typical value of 2.0. An air to fuel mass ratio of 1.8 produces a primary stoichiometric ratio of approximately 0.16, or 16% of the air necessary for complete combustion of the coal.

Coal-mill optimisation in coal-fired power stations

The ideal size is taken as 74 μm or smaller, but standards allow a range of larger particles, the amount decreasing with size until the maximum size acceptable is reached. The standard test applied to ground coal particles measures the percentage of a sample that passes through a series of sieves of decreasing size.
