Abstract

Control of NOx has been a major issue in designing combustion systems, since NOx plays a key role in ozone depletion and the generation of photochemical smog. Flue gas recirculation (FGR) is one of the well-known methods to control NOx emission. The recirculated flue gas in fuel stream, that is, the fuel induced recirculation (FIR) could enhance a much greater reduction in NOx per unit mass of recirculated gas, as compared to the conventional FGR in air. The effect of FGR/FIR methods on NOx reduction in turbulent swirl flow flame in laboratory scale using N2 and CO2 as diluent gases to simulate flue gases were studied. The NO reduced following the diluent recirculation ratio increasing and CO2 dilution is more effective because of large temperature drop due to the larger specific heat compared to N2. FIR is more effective to reduce NO emission that FGR when the same recirculation ratio of dilution gas is used. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
