Many times water or steam injection is used in conjunction with other NOx control methods such as burner modifications or flue gas recirculation. Flue Gas Recirculation. Flue gas recirculation or FGR is the most effective method of reducing NOx emission from industrial with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into theGet a Quote

Flue Gas Exit Temperature is corrected for inlet air temperature X1 = Reference Air Temp * (Gas Temp In Gas Temp Out) + Gas Temp In * (Gas Temp Out - Air Temp In) X2 = Gas Temp In - Air Temp In EGTcor. = X1/ X2 = 35 * (345-143.9) + 345 (143.9 41.6) / (345 41.6) = 139.5 C EGT Corrected for inlet air temp and for AH leakage = AL * Cpa * (EGTcor - Tair in) + EGTcor Cpg * 100 = [13.7* (139.5 41.6)] / 100 + 139.5 =Get a Quote
