Flue Gas Recirculation: History and Uses - EnviroPower

Typical flue gases from natural gas-fired power plants may contain 8-10% CO 2, 18-20% H 2 O, 2-3% O 2, and 67-72% N 2; typical flue gases from coal-fired boilers may contain 12-14 vol% CO 2, 8-10 vol% H 2 O, 3-5 vol % O 2 and 72-77% N 2.

Sep 26, 2018 · For large boilers (1MW and above), typical NO x levels are currently likely to be above 70 mg·kWh ¹ although it is difficult to be specific because there are many combinations of boiler and burner, with the actual levels being influenced by combustion chamber, burner head and flame type, and geometry.. Flue gas recirculation. The flame temperature may be reduced and so lessen NO

Boiler - Wikipedia

Jun 19, 2019 · Flue Gas Recirculation (FGR) is the process of taking a portion of the flue gas from a combustion process and recirculating it back through a boiler or burner. When the process is used in internal combustion engines it is commonly referred to as exhaust gas recirculation (EGR). FGR has two primary purposes and one just for gasifiers.

Natural Gas Fired Boilers - innovativecombustion.com

Dec 06, 2020 · Boilers cannot burn of the gas they use so the remaining combustion gases (made up of water vapour, carbon dioxide, particulates, heavy metals and acidic gases) need to be removed via the flue. The position of the flue is important as the combustion gases must not re-enter a property via a close-by window or cause a nuisance by discharging

Module 106: Natural gas boiler flue gas recirculation to

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
