The effectiveness of recirculating flue gasses on a gas

The effects of flue gas recirculation ratio, air preheating temperature, oxygen concentration, and fuel types on pollutants emission in the volumetric combustion system were investigated. According to the results, it was con- cluded the higher substitution ratio of biomass in a co-firing boiler, the lower emissions of NOx and SOx.

Flue Gas Recirculation (FGR) - CCA Combustion Systems

The results of investigating the effect of recirculating flue gasses on a TP-87 boiler (D = 420 tons per hour, 14 MPa, 560 C) with a hearth composition of four gas-fuel oil burners are presented. The heat-release rate of the volume of the furnace is 136 Kw per m/sup 3/; that if a cross section of the combustion chamber is 3.2 MW/m/sup 2/.

Effect of flue gas recirculation during oxy-fuel

Jan 01, 2014 · They found that the efficiency of the oxy-fuel process is increased due to flue gas energy recovery, and the CO 2 emission is lower relative to the air combustion process. However, energy consumption was increased when using the oxy-fuel process due to the presence of additional CCS units.

Aug 09, 2018 · Overfire air and flue gas recirculation (OAFGR) systems can offer significant benefits to a stoker-fired boiler system, ranging from more efficiency to fewer emissions. Overfire Air and Flue Gas Recirculation Explained In this configuration, flue gas is taken from downstream of the boiler and combined with combustion air from a draft fan.

Effects of flue gas recirculation on energy, exergy

Nov 17, 2020 · In this study, energy, exergy, environment, and economic (4E) analyses were performed for a 500‐MW e oxy‐coal ultra‐supercritical circulating fluidized‐bed (CFB) power plant with CO 2 capture. The effect of the location of flue‐gas recirculation (FGR) on the 4E values was investigated for wet FGR (wFGR) at 170°C, dry FGR (dFGR) at 68

Effect of Flue Gas Recirculation (FGR) on NOx Emission in

In case of the swirl flame, flue gas recirculation leads to a reduction of NOx emissions up to 50%, whereas in case of flameless combustion this reduction is around 40% compared to CO2/O2.
