### Understanding PPMVD and O2 Level Requirements - Boiler ...

Jun 06 2018 · The ref. 3% O2 is required as a benchmark for the oxygen content in the flue gas. This is because the boiler will operate at various O2 levels and the air district needs to normalize the measurements. Sometimes emission limits are referenced with different O2

### Power plant and calculations: Boiler calculations for ...

Feb 12 2021 · 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 Boilers 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

### Conversion Factors - CleanBoiler.org

Conversion Factors. Correcting for Oxygen Concentration In order to compare NOx concentrations on an equivalent basis the field measured readings are corrected to a reference oxygen concentration. This reference concentration is typically 3% oxygen (dry volume basis) for boiler applications.
