Flue gas refers to a chemical byproduct substance that is generated as a result of a combustion reaction that has escaped through long pipes such as those in boilers, furnaces or steam generators. Flue gas may also be referred to as exhaust gas and may act as a reactor agent for atmospheric corrosion.
from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox, the recirculated gas is mixed with combustion air prior to being fed to the burner. The recycled flue gas
What’s a boiler flue? This is a special pipe that takes away the fumes and provides the needed amount of fresh air to the boiler. Before installing a heating unit, a user should be well-acquainted with the gas boiler flue regulations.
After reading here and elsewhere that the corrodant in flue gas condensate was carbonic acid, it didn't track with my understanding. So I dug out the original research from the early 1980s by Battelle-Columbus Laboratories for the Gas Research Institute (Report No. GRI-85/0282, Technology Development for Corrosion-Resistant Condensing Heat Exchangers).

Flue Gas Analysis as a Boiler Diagnostic Tool Overview, and Traditional Application 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
A common application of economisers in steam power plants is to capture the waste heat from boiler stack gases (sometimes known as flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler output.
