Burned gas properties of the rapidly mixed type combustion in a tubular flame burner have been experimentally investigated. Results show that the flammable range for the rapidly mixed type combustion is almost the same as that for premixed type combustion except that the rich limit is slightly narrowed, the burned gas compositions and temperature at the burner exit are also almost the same as those of the premixed type combustion, while the NOx emission are 10-15 % less than that of premixed type combustion for lean and the stoichiometric mixtures. These results demonstrate the potentialities of the rapidly mixed type combustion in a tubular flame burner, which is free from flame flash-back accident.
