D134 Effects of oxygen concentration on the radiative characteristics of NH_3/N_2/O_2 laminar premixed flame

Abstract

The total radiative heat flux and the radiation spectra of the ammonia flame were measured to understand the radiative characteristics of ammonia flame in this study. A slot burner was used for stabilizing the laminar ammonia/N_2/O_2 premixed flame. The concentration of O_2 in the oxidizer and equivalence ratio were varied for increasing the flame temperature. The results showed that radiative heat flux of ammonia was lower than that of methane/air premixed flame in all condition of that has the same net heating values per unit time.
