Measuring false air in cement production
V2 = false air volume Vt = total volume (V1 + V2) False air will drop plant efficiency Because the air mix is so critical, it is important to avoid air leaks (also known as 'False air'), where additional unwanted air enters the process. One way of finding false air in gas streams of less than 21 % oxygen is to measure the oxygen content at
