CO₂ is a well-known green house gas, which is the major source of global wanning. Many
researchers have studied to reduce CO₂ emission in combustion processes. Among the method for reducing CO₂ emission, oxygen-enriched combustion has been proposed. But the adiabatic name temperature is too high. So existing facilities must be changed, or the adiabatic name temperature in the combustion zone should be reduced. The combustion characteristics, composition in the name zone, temperature profile and emission gases were studied experimentally for the various oxygen-enriched ratios(OER) by addition of CO₂ under constant O₂ flowrate. Results showed that the reaction zone was quenched, broadened, as addition of CO₂ was increased. Temperature has a large effect on the
NOx emission. The emission of NOx in flue gas decreased due to the decreased temperature of
reaction zone. It was also shown that the reaction was delayed by the cooling effect As the addition of CO₂ was increased, the composition of CO in the name zone increased due to the increase of reaction rate by increasing mixing effect of oxidant/fuel at OER=O, but the composition of CO decreased by quenching effect at OER=50 and 100%.
