Abstract

Brüleur à air soufflé, comprenant une tête de combustion (1) montée sur un carter (3) en s'étendant suivant une direction axiale (A), une turbine de ventilation (5) montée autour d'un axe de rotation (9) fixe par rapport au carter (3) et un diffuseur (11) du carter pour diriger un flux d'air comburant généré par la turbine de ventilation vers la tête de combustion en s'étendant dans un plan (P) du carter perpendiculaire à l'axe de rotation (9) de la turbine de ventilation (5) et incliné par rapport à la direction axiale (A) de la tête de combustion (1).Blast furnace, comprising a combustion head (1) mounted on a housing (3) extending in an axial direction (A), a ventilation turbine (5) mounted about an axis of rotation (9) fixed relative to the housing (3) and a diffuser (11) of the housing to direct a combustion air flow generated by the ventilation turbine to the combustion head by extending in a plane (P) of the housing perpendicular to the axis of rotation (9) of the ventilation turbine (5) and inclined with respect to the axial direction (A) of the combustion head (1).

Selon l'invention, le diffuseur (11), dans le plan (P) perpendiculaire à l'axe de rotation (9), s'étend suivant une direction de diffusion (D) faisant un angle de diffusion (b) compris entre 10 et 50 degrés, de préférence entre 20 et 50 degrés, avec une projection de la direction axiale (A) de la tête de combustion (1) dans le plan (P) perpendiculaire à l'axe de rotation (9).

Figure imgaf001
According to the invention, the diffuser (11), in the plane (P) perpendicular to the axis of rotation (9), extends in a diffusion direction (D) making a diffusion angle (b) between 10 and 50 degrees, preferably between 20 and 50 degrees, with a projection of the axial direction (A) of the combustion head (1) in the plane (P) perpendicular to the axis of rotation (9).
