FIELD: heating, roasting, melting and retort furnaces.
SUBSTANCE: thermal cutter for perforating and/or cutting of materials is proposed. Thermal cutter comprises at least four cylindrical profiles, one outer and three inner, and more than seventeen cavities contained inside said cutter. At least two of said four cylindrical profiles have different cross sections and each cylindrical profile is located adjacent to the rest of said cylindrical profiles. Each cylindrical profile is selected from cylindrical profiles with cross-section of round, square, triangular, hexagonal, oval shape and shape of multi-pointed star.
EFFECT: higher concentration of generated energy and possibility to control flow of oxidizing gases.
