Oxyfuel Combustion - an overview | ScienceDirect Topics

Sep 26, 2018 · Generally, the boilers are slightly down-rated to enable more favourable mixing in the combustion chamber. The recirculated flue gases are normally drawn into the burner by the burner fan but, for larger appliances, there might be an additional fan. The burner damper is progressively opened as the burner modulates up.

Flue Gas Recirculation (FGR) - CCA Combustion Systems

Flue Gas Recirculation (FGR) is a powerful nitrogen oxide (NOx) control technique that significantly reduces NOx emissions by recirculating flue gases from the boiler exhaust duct into the main combustion chamber. This process reduces peak flame temperature and lowers the percentage of oxygen in the combustion air/flue gas mixture, thereby reducing thermal NOx formation.

Recycled Flue Gas - an overview | ScienceDirect Topics

Excess oxygen at burner inlets increases with increasing recycled flue gas for recycle flue gas containing 3.3% oxygen. When 71% of flue gas is recycled, 15.9% and 12.6% excess oxygen at burner inlets is obtained for wet and dry recycle oxy-fuel combustion respectively.

Flue Gas Recirculation for NOx Reduction

(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 can typically operate at recirculation rates of 20-25 percent without adversely affecting boiler heat transfer and …

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.

side of the boiler where the flue gas temperature is low, fume becomes more significant and thus the deposit chemistry is closer to that of fume. Deposits may react with SO2 and SO3 in the flue gas, converting some carbonate and chloride to sulphate. Figure 7 shows typical compositions of deposits at various locations in the boiler.
