In accordance with the method and the device according to the invention, previous pure pyrotechnic primers for initiating the ignition charges ( 6 a, 6 b) of the oxygen lance igniters ( 13 ) are replaced by a small quantity of powdered zirconium ( 7 ). Zirconium is pyrophoric and therefore ignites, providing it has a sufficiently large surface area, in the presence of a sufficient quantity of pure oxygen, although in ordinary air it is no more flammable than ordinary wood. |
