1.4 Natural Gas Combustion

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

Definition of a Boiler Flue: A boiler flue is a component, which enables gases to escape safely. In most cases, this is a pipe or a duct, which is fitted to the boiler to carry exhaust gases away from your home safely. The aim is to remove waste products without exposing you or anyone around you to them.

Flue Gas Recirculation: History and Uses - EnviroPower

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.

Boiler - Wikipedia

Early boilers provided this stream of air, or draught, through the natural action of convection in a chimney connected to the exhaust of the combustion chamber. Since the heated flue gas is less dense than the ambient air surrounding the boiler, the flue gas rises in the chimney, pulling denser, fresh air into the combustion chamber.

Aug 09, 2018· In this configuration, flue gas is taken from downstream of the boiler and combined with combustion air from a draft fan. (The flue gas may also be mixed with overfire air in certain configurations). What this process does is simple: it replaces the excess air that the stoker usually uses with recirculated flue gas.
