Flue Gas Analysis | CleanBoiler.org

Flue Gas Analysis is performed by inserting a probe into the flue of the furnace, boiler, etc., between the last heat exchanger and draft diverter or any source of make-up air that could enter the flue that did not pass through the combustion process. This is known as 'in-situ' testing.

Effects of Presence of Dissolved Gases in Feed Water

Carbon dioxide enters the system with the boiler feed water in dissolved form & in form of bicarbonates. The carbon dioxide is carried away with the steam & is condensed to form carbonic acid. Carbonic acid has a capacity to combine with one and a quarter pound of steel per pound of CO2, forming a groove at the bottom of the piping .
