Abstract
A ceramic burner is provided, particularly for use in a hot-blast oven, with a generally cylindrical wall defining a central burner duct and a housing extending around and spaced from the generally cylindrical wall to define an outer annular duct disposed coaxial to the central burner duct. The generally cylindrical wall includes an inner peripheral surface extending outwardly from a central burner duct to define a burner mouth. First and second ring nozzles are provided having openings extending from the outer annular duct and open at the burner mouth. Nozzle inserts are provided for insertion into the openings of the first and second ring nozzles so as to vary the cross-sectional area defined by the openings of the first and second ring nozzles. Additionally, injector grids are provided for insertion into the openings of the first and second ring nozzles so as to divide each of the openings into a plurality of smaller openings. The ceramic burner may also be provided with a third ring nozzle, extending from the outer annular duct and open at the central burner duct, which is located below the burner mouth.
