There is no any standard formula to convert mesh to microns but we can roughly convert by dividing 14900 by the given mesh size (micron = 14900/mesh). For example, 60 mesh will be equal to 14900/60 = 248 microns.

Modern boilers powder the coal to a very fine dust so that while burning, it is almost like a fluid stream. The size of the coal particles is in the range of 75 microns. This means every particle comes into contact with the air. The loss due to unburned carbon is only in the range of % or less making the boilers very efficient.
