boiler Agent exhaust flue gas of co2 percentage

Combustion Efficiency and Excess Air

Carbon dioxide - CO 2 - is a combustion product and the content of CO 2 in a flue gas is an important indication of the combustion efficiency. Optimal content of carbon dioxide CO 2 after combustion is approximately 10% for natural gas and approximately 13% for lighter oils.

Flue Gas Analysers Guide - Keison

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

23/8/2012 · 1,290. Aug 23, 2012. #12. Gas pressure is the easiest thing to start with, obviously BP and IWP on old boilers and just IWP on new ones. From there you need to be gas rating and checking the integrity of the flue. On some condensing boilers the gas valve is adjustable to get the perfect ration and co2 percentage.

Flue Gas - an overview | ScienceDirect Topics

The flue gas enters the lower part of the desulfurization absorption column under the action of the booster fan after being dusted by the dust collector. In the rising process, it comes into full contact with the falling limestone slurry sprayed by the spray. SO 2 in the flue gas is absorbed by the slurry and falls into the slurry pool at the bottom of the column.

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.

On a dry basis the percentage of carbon dioxide in the in the flue gas is 1/9 or 11.1% (vol.). This is broadly similar to many natural gases where methane (and some higher hydrocarbons) substitute for the nitrogen. However, in practice the flue gas is far more complicated. Firstly it is common practice to conduct combustion with at least 10% excess air, this ensures minimum soot (particulate emissions) …
