How to calculate the flue gas volume at 6%
Thread Content
Given the flue gas volume under standard conditions in the power plant, determine the flue gas volume at 6% oxygen content. I don’t know what 6% oxygen means. Please help answer this beginner’s question. Thank you!
This is the volume concentration; it should be calculated using the standard condition flue gas volume divided by 94%
The original oxygen level should remain unchanged, with air being added to bring the oxygen content to 6%. The formula is: Volume of flue gas at 6% oxygen = (Volume of flue gas at 21% – Oxygen content in the flue gas) / (21% – 6%)
Is it the oxygen content? My humble opinion~~~~
The information on the 4th floor is basically correct, but it needs to be adjusted: the flue gas volume at 6% oxygen level = flue gas volume under actual oxygen content × (21% – actual oxygen content) / (21% – 6%)
When power plant exhaust gases are released, the oxygen content is generally around 6%. Due to differences in the systems, the air leakage coefficients of boilers and flues vary; therefore, for uniform comparison, adjustments are necessary, with additional air being supplied. There are **standards** for this.
