purge rotameter for coal mill

A boiler is fired with a coal having following analysis by percentage weight. The coal is burned using 40% excess air and produces ash containing 25% unburned carbon. Determine • Volume of air required to burn 1 kg of coal • Actual volume of air • Percentage composition of dry products of combustion. C=54. H=4. O=12. N=1. S=4. A=22. M=3

Coal from travelling belt of raw coal feeder drops in central feed pipe ( connection between Raw Coal Feeder and Mill). After coal reaches Mill bowl grinding started and hot air also been given to make the pulverised fuel dried enough to classifier chamber. The portion of the coal which cannot be grinded finds its way to mill reject.
