### Chapter 3: Review of Basic Vacuum Calculations

Apr 19, 2021 · We have excess air EA = O2 X 100 / (21-O2) EA = 4.7 X 100 / (20-4.7) EA = 30.71% 2-Calculate the Oxygen level (O2) in flue gas, if excess air is 25% We have Excess air EA = O2 X 100 / (21-O2) 25 = O2 X 100 / (21-O2) O2 = 4.2% 3-A Boiler's combustion system requires 5.5 kg of air for burning 1 kg of fuel, then calculate the total air required for complete combustion if its flue gas has 4.1% of O2 We have, Total air = (1 + EA/100) X Theoretical air EA = O2 X 100 / (21-O2) EA = 4.1 X 100
