Re: calculation of false air entry in coal mill
You can use:
1. Mass balance
2. Heat balance
3. Oxygen balance (oxygen correction)
easiest is Oxygen balance that you measrue oxygen going in and out and do oxygen balance base on this formula:
V2 = Vt (21-Oout)/(21-Oin)
V2 = false air valume
Vt = total volume (V1 + V2)
Oout = Oxygen % in total volume
Oin = Oxygen % in inlet
