As with other gases, the composition of flue gas depends upon the composition and properties of the fuel being combusted but, nevertheless, the composition will usually consist predominantly of nitrogen (usually on the order of 60% v/v and higher derived from the combustion process using air as the oxidant, carbon dioxide, and water vapor), as well as any excess oxygen (also derived from the air).

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

• ### Flue gas - Wikipedia

33 rows · Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants. Its composition depends on what is being burned, but it will usually consist of mostly nitrogen derived from the combustion of air, carbon dioxide, and water vapor as well as excess oxygen. …

Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel. You can also refer to Thermodyne's Boiler Bible that provides you the general composition of above elements for various fuels.
