Characteristics of the reaction zone in a combustor operating at mild combustion

The study of mild combustion mode for both non-premixed and premixed mixture preparation was presented. The aerodynamic, chemical and thermal aspects of the mild combustion process were also studied in a combustor. The mixing rates, flue gas recirculation and strong shear produced by reactants from discrete jets were emphasized for the study. The results revealed that for the initiation and progress of the reaction the entertainment of flue gases in the fresh mixture was very important. It was also shown that the combustion region shifted away from the burner and extended further downstream with increase in equivalence ratio of nonpremixed mixture.
