H atoms in a Bunsen-type methane-air flame have been studied by observing their ESR signals at different flow rates of O<SUB>2</SUB> and N<SUB>2</SUB> in a synthetic secondary air. The optical emissions from excited CH, C<SUB>2</SUB>, and OH radicals in the same flame have been also studied. It has been found that an increased O<SUB>2</SUB> flow rate produces changes in the intensity of the ESR and emission signals, and that it also increases the burning velocity in the inner-cone flame. An increased N<SUB>2</SUB> flow rate, on the other hand, has almost no effect on the flame. The inner-cone of a Bunsen-type flame is, therefore, not a completely premixed flame; it is affected chemically by the secondary air.
