Application Note: Flue Gas Analysis as a Boiler Diagnostic

Combustion flue gas analysis has been used by Power Plant Operators for decades as a method of optimizing fuel/air ratio. By measuring the amount of excess oxygen and/or CO in the flue gases resulting from combustion, plant operators can operate at the best heat rate efficiency, lowest NO x, and also generate the least amount of greenhouse gas.
