Abstract
The apparatus operates to supply the air requirements for grinding a fuel material to the mill to guarantee the correct particle size and to decouple from the air emitted from the grinding apparatus a certain proportion so the combustion of the ground fuel material will be conducted at a ratio of less than the usual 3 to 1 ratio of air-to-fuel so the combustion can be controlled to reduce the nitrous oxide emission, the air that is decoupled is returned to the grinding apparatus with a supply of make up air that is heated for purposes of drying the material in the grinding apparatus.
