A self-regenerating industrial burner including a head with which at least one first fuel injection nozzle, associable at an inlet with a fuel supplying group, and at least one pair of second nozzles, that can be alternatively and selectively passed through by combustion air and combustion exhaust gases, are associated; a tubular body open at opposite ends, arranged at a front part of the head and coaxial to the at least one first nozzle with an end close to the face of the head at which the first nozzle and the at least one pair of second nozzles protrude and the opposite end distant from the face. Each second nozzle includes at least one first tubular portion, radially lying outside the tubular body and defining at an end at least one first port, alternatively for exit of the combustion air and for inlet of the combustion exhaust gases. |
