Novelty: high-temperature pilot flame consisted of an iron tube is disclosed. Constitution: an iron tube 1 containing a spiral iron lamella 2 and aluminium wires 3. High-temperature flame is produced by the oxygen supplied from the one end of the iron tube and the partial incandescence of the other end what leads to the combustion of the iron; the combustion of the aluminium is also contributing to this purpose. Advantage: the swirl of the gas inside the iron tube implies, to a great extent, the perfect combustion of the iron and, thereby, the higher temperature production; long consumption due to the increased iron quantity measured by unit of length. Embodiment: the invention finds application to the perforation, cutting and melting of metals and other materials. |
