“…With the external FGR technique, it is possible to obtain stable combustion and lower NO x by 20% to 80%, and by adjusting the flue-gas recirculation rate 15% to 30%. The effect of high CO 2 and H 2 O levels in the flue gas is to increase the specific heat capacity of the burned gases for a given quantity of heat release, thus lowering the operating temperatures [4][5][6][7][8].…”

Flue gas recirculation (FGR) is an effective applicable way to reduce emissions. In the present study, external FGR was employed in non-premixed combustion using kerosene as liquid fuel to investigate its effect on flame stability, appearance and emissions. Flame stability can be attained through a reasonable range of recycling ratios up to 40%. Flame appearance exhibits shorter flame with increasing FGR% due to the increased turbulent mixing. Flame temperature was reduced because of dilution effect and increased specific heat of FGR. The flame luminosity decreased and bluish flame increased by increasing FGR%. As a result of the flame temperature decrease, an obvious reduction of NO emissions can be achieved. The NO can be dropped from about 90 ppm to a single digit number. Emissions of CO and UHC increased at high recycling ratios near to flame blow-off and more increase took place at leaner conditions i.e. lowest flame temperature.

“…These researchers investigated the performance and operability of a combustor from a GE F-Class turbine. Another by Rokke and Hulstad [14] investigated the impact of the addition of oxides of nitrogen (NOx), O 2 and CO 2 on a smaller 65kW burner, and similar investigations were undertaken by Jansohn, et al [15]. However these focused on the combustor performance isolated from the turbine, and not the whole system.…”

“…However, to reduce the impact of the low percentage of CO2 in the flue gas on the CO2 capture costs, the current research in this field aimed at increasing the CO2 concentration in the flue gas in order to enhance the CO2 absorption performance and hence reduce the operational and investment costs. Some of the different strategies to increase CO2 in natural gas flue gas are listed below [111][112][113].…”
