FIELD: power engineering.
SUBSTANCE: burner (1) for firing ceramic products (T), made with the possibility of installation in an industrial furnace (2) containing a chamber (3) firing; moreover, the burner (1) contains: a mixing body (5), containing, in turn, at least one channel (6) for supplying fuel (FL); at least one channel (7) for supplying an oxidant (OX); starting device (8) for starting combustion; a flame detection device (9); the first tubular outlet element (11), made with the possibility of passing through it the fluid (F) flowing from the mixing body (5), and provided with the first end (12), inside which at least a part of the mixing body (5) is inserted, and the second end (14) opposite the first end (12). The burner (1) also contains at least one second tubular outlet (18) that extends from the second end (14) on the opposite side to the first end (12); and a suction element (19) configured to deliver at least part of the gases (G, G') present outside the burner (1) into a second tubular outlet (18) and provided with one or more holes (20) located between the first (11) and second (18) tubular outlets; moreover, the mixing body (5) contains a multi-stage combustion head (10) located at least partially inside the first tubular outlet element (11).
EFFECT: reduced emission of harmful substances into the atmosphere.
