Title
(EN) ARRANGEMENT FOR EVENING OUT POWDERY SOLID MATTER FEED OF A CONCENTRATE BURNER OF A SUSPENSION SMELTING OR SUSPENSION CONVERTING FURNACE
(FR) AGENCEMENT POUR ÉGALISER UNE CHARGE DE MATIÈRE SOLIDE POUDREUSE D'UN BRÛLEUR DE CONCENTRÉ D'UN FOUR DE FUSION À SUSPENSION OU DE CONVERSION À SUSPENSION
Abstract
(EN)
The object of the invention is an arrangement for feeding powdery solid matter into a concentrate burner (2) of a suspension smelting or suspension converting furnace (1). The concentrate burner (2) comprises reaction gas feeding means (6), powdery solid matter feeding means (3) and a concentrate distributor (7). The arrangement comprises a first powdery solid matter discharge pipe (8) for feeding powdery solid matter into the powdery solid matter feeding means (3) of the concentrate burner (2). The first powdery solid matter discharge pipe (8) is provided with a first partition (10), which divides solid matter, for dividing the first powdery solid matter discharge pipe (8) into two essentially similar discharge pipe parts (11). The powdery solid matter feeding means (3) of the concentrate burner (2) comprise an annular concentrate discharge channel (4) that surrounds the concentrate distributor (7) of the concentrate burner. Each discharge pipe part (11) of the first powdery solid matter discharge pipe (8) is at least partly divided into two discharge pipe portions (12) by a second partition (13).
(FR)
La présente invention concerne un agencement conçu pour alimenter une matière solide poudreuse dans un brûleur de concentré (2) d'un four de fusion à suspension ou de conversion à suspension (1). Le brûleur de concentré (2) comprend des moyens d'alimentation en gaz de réaction (6), des moyens d'alimentation en matière solide poudreuse (3) et un distributeur de concentré (7). L'agencement comprend un premier tuyau d'expulsion de matière solide poudreuse (8) pour acheminer une matière solide poudreuse à l'intérieur des moyens d'alimentation en matière solide poudreuse (3) du brûleur de concentré (2). Le premier tuyau d'expulsion de matière solide poudreuse (8) est doté d'une première cloison (10), qui partage la matière solide, divisant le premier tuyau d'expulsion de matière solide poudreuse (8) en deux parties de tuyau d'expulsion (11) sensiblement similaires. Les moyens d'alimentation en matière solide poudreuse (3) du brûleur de concentré (2) comprennent un canal annulaire d'expulsion de concentré (4) qui entoure le distributeur de concentré (7) du brûleur de concentré. Chaque partie de tuyau d'expulsion (11) du premier tuyau d'expulsion de matière solide poudreuse (8) est au moins partiellement divisée en deux sections de tuyau d'expulsion (12) par une seconde cloison (13).
