BURNER WITH HIGH FLAME STABILITY PARTICULARLY FOR THE THERMAL TREATMENT OF CERAMIC ARTICLES

摘要

A burner (1) with high flame stability particularly for the thermal treatment of ceramic articles comprising a supporting body (2) provided with at least one first port (4) for the inflow of an oxidizing fluid and with at least one second port (5) for the inflow of a combustible fluid and a combustion head (7) which is associated with the supporting body (2) and is provided in its central region with nozzle means (8) which are associated with the second port for the outflow of the combustible fluid in a combustion region (9) and in its peripheral region with an annular diffuser (14) provided with a plurality of through openings (15) for orienting the flow of the oxidizing fluid toward the combustion region. At least one of the openings (15) comprises a slot (15a) which is provided inside the diffuser (14) and has an extension along a first transverse dimension that is substantially larger than the extension along a second direction that is transverse to the first direction.
