Abstract: It is found that charged nitrogen oxides are formed not only in the front and the high-temperature combustion-product zone of a Bunsen-type flame but also in the relatively cold external region of the flame close to the burner nozzle. The peripheral NO$^+$ is formed from atmospheric oxygen drawn in from outside the flame. The concentration of NO$^+$ ions increases as the mixture is enriched with fuel. Possible pathways by which the peripheral NO$^+$ ions may appear are considered. It is suggested that their precursor is the NH$^+_4$ ion formed from ammonia.
