4. ROLE OF MILLS • Produces Pulverized coal 80% of which passes through 200 mesh • Air mixed with Pulverized coal (PF) is carried to the coal nozzle in the wind box assembly. • PF from coal nozzle is directed towards the center of boiler burning zone • Preheated secondary air enters boiler and surrounds the PF and help in combustion. 5.

These proportions depend on the polydispersity number n, which is mainly connected with the classifier design and also with the type of pulveriser. In typical installations for coal n =, where the lower values correspond to highspeed pulverisers ( fan mills), while the higher numbers correspond to the medium and lowspeed mills.
