<p>A cutting torch and a cutting nozzle (1) having at least one heating-oxygen duct (2), having at least one heating-gas duct (3), having a cutting-oxygen duct (4), which has a de Laval nozzle (5) with a convergent and a divergent section (6, 7), and having a nozzle head (8) are shown, said nozzle head (8) having a clearance (9) into which the heating-oxygen duct (2), the heating-gas duct (3) and the de Laval nozzle (5) of the cutting-oxygen duct (4) lead. In order to create a stable post-mixing cutting nozzle (1) having improved efficiency, it is proposed that the de Laval nozzle (5), leading into the clearance (9) in the nozzle head (8), is in the form of a parallel jet nozzle.</p> |
