May 07, 2020 · 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

The heat efficiency of a flue gas waste heat boiler is the percentage of the effective heat in the heat injected into the fuel. The anti-balance test method is usually used to measure boiler thermal efficiency. The calculation formula for the thermal efficiency of the anti balance method: η= 100- (q2+q3+q4+q5+q6) 1. q2-flue gas heat loss
