## calculation of false air entry in coal mill Page 1 of 1

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
