Flue Gas Analysis Table | CleanBoiler.org

CO is the most sensitive indicator of incomplete combustion. As the amount of excess O 2 is reduced, the emergence of CO will occur before other combustibles appear (unburnt fuel). When the concentration of CO reaches the desired setpoint (typically around 400 ppm), the excess O 2 concentration is at the desired level and becomes the new excess O 2 setpoint.

Application Note: Flue Gas Analysis as a Boiler Diagnostic

Feb 04, 2016 · Using a Flue Gas Analyzer or any meter designed to measure oxygen or carbon-monoxide, and taking the flue gas temperature and the temperature of the combustion air, the following Table can be used to determine combustion efficiency when operating on natural gas. The Temperature Column is the NET Difference between Flue Gas and Combustion Air Temperatures.

Carbon Monoxide CO is usually the first combustible gas component to appear when combustion fuel/air ratios start becoming too rich. Desired CO levels in combustion flue gases are typically less than 200 PPM, and infra-red spectroscopy is well suited to measuring at these low levels.2 Repeatabilities of better than +/-5 PPM are possible, with low
