What is false air. False air is any unwanted air entering into the process system. The exact amount of false air is difficult to measure. However, an indicator of false air can be, increase of % of oxygen between two points (usable for gas stream containing less than 21 per cent of oxygen). Due to unwanted air, the power consumption increases ...
Measuring false air in cement production
inlet) % of false air = * 100 % (20,95 % – O 2 % inlet) Whereas 20,95 % O 2 is said to be the average concentration of oxygen in dry air. But the calculation can also be done as a calculation of the total volume of false air: (20,95 % – O 2 % outlet) V2 = Vt * (20,95 % – O 2 % inlet) Where V1 = normal volume V2 = false air volume

Damper Actuator Applications Guide
Damper control alone is itself not responsible for the indoor air quality and climate, but it has a very central role. Therefore, it is important that the dampers and actuators are selected and sized correctly. Damper Selection Traditionally, little attention is given to the selection of the dampers that comprise the economizer.

quarterly accuracy audit option and for daily calibration drift assessments. For example, PS15 allows validation of an HCl CEMS analyzer based on DSA results without the need to perform a relative accuracy test. For this study HCl dynamic spikes were performed using N 2O as a tracer gas. Sixth, for different in-line raw mill operating conditions
