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

Boiler Efficiency - an overview | ScienceDirect Topics

The most common test used for boilers is the flue gas analysis using an Orsat apparatus to determine the percentage by volume the amount of CO 2, CO, O 2, and N 2 in the combustion gas leaving the stack. Based on the flue gas composition and temperature, some adjustments can be made to tune-up the boiler and to determine the best air-to-fuel

Adapting Boilers to Utilize Landfill Gas: An

(inert) gas in LFG is equivalent to the inert gas entering a boiler when about six percent of the flue gas is recirculated to the boiler. Flue Gas Recirculation (FGR) is a widely applied technique for reducing nitrogen oxide (NOx) emissions from natural gas-fired industrial and commercial boilers, and boilers …

Adapting Boilers to Utilize Landfill Gas: An

This is because the flue gas velocity of x = 0.1 m, which is near the entrance to the convection chamber, is less than that of x = 1.0 m, leading to a smaller heat transfer coefficient and thus a lower flue gas temperature. The flue gas of upward flow carries out heat exchange with the tubes, and the flue gas temperature field also gradually becomes uniform.
