A burner head (1), suitable for use in a furnace, has an array or matrix of combustion air apertures divided into three (outer, middle and inner) aperture rings (6, 7, 8). Gaseous fuel is conveyed down central fuel pipe (9) which flows through gallery (G) to individual broached apertures (6a, 7a, 8a) of aperture rings (6, 7, 8), which fuel mixes with combustion air being drawn up through the centre of said apertures. The aperture matrix is configured to eliminate anomaleous "hot spots" which would accelerate corrosion as well as equalising flow distribution through the gallery (G) to the apertures (6a, 7a, 8a).
Une tête de brûleur (1), adaptée pour être utilisée dans un four comporte un réseau ou une matrice d'orifices d'air de combustion divisé en trois (extérieur, milieu et intérieur) anneaux d'orifices (6, 7, 8). Du combustible gazeux est transporté jusqu'à un conduit (9) de combustible central passant dans une galerie (G) jusqu'à des orifices individuels brochés (6a, 7a, 8a) d'anneaux d'orifices (6, 7, 8), ledit combustible se mélange alors à de l'air de combustion aspiré par le centre desdits orifices. La matrice d'orifices est configurée pour éliminer les "points chauds" anormaux qui pourraient accélérer la corrosion, ainsi que pour égaliser la répartition de l'écoulement à travers la galerie (G) jusqu'aux orifices (6a, 7a, 8a).
