Flue gas heat recovery | Industrial Efficiency Technology & …

Heat recovery from flue gas is often the best opportunity for heat recovery in steam systems (CIPEC 2001). Heat from flue gas can be used to preheat boiler feed water in an economizer. While this measure is fairly common in large boilers, there is often still room for more heat recovery. The limiting factor for flue gas heat recovery is that one must ensure that the economizer wall temperature

BOILERS | Energy-Models.com

The flue gas exit tempera ture from a boiler is usually maintained at a minimum of 200 o C, so that the sulphur oxides in the flue gas do not condense and cause corrosion in heat transfer surfaces. When a clean fuel such as natural gas, LPG or gas oil is used, the economy of heat recovery must be worked out, as the flue gas temperature may be well below 200 o C.

1.4 Natural Gas Combustion - United States Environmental Protection Agency …

CO2, CH4, and N2O emissions are all produced during natural gas combustion. In properly tuned boilers, nearly all of the fuel carbon (99.9 percent) in natural gas is converted to CO2 during the combustion process. This conversion is relatively independent of

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.

Flue gas analysers usually display a CO/CO2 ratio. This shows the ratio of carbon monoxide and carbon dioxide in the exit flue (chimney) of the appliance. Generally when this level is below 0.004 the boiler is considered to be running efficiently. When between 0.004 and 0.008 this indicates a potential problem and investigation and retesting
