Abstract
The invention relates to the electric ignition of oxy-fuel burners, as well as to the detection of the flame of these burners. A spark is induced between an electrode and the body of the burner, the said electrode being situated in the area of the recirculation flows having a relative proportion of oxygen and fuel comprised between the lower and upper limits of flammability, close to the said upper limit. The invention is applicable to burners supplied with a gaseous fuel.
