Title (EN) OXIDANT SUCTION CUPOLA AND METHOD FOR MANAGING SAME
(FR) CUBILOT A ASPIRATION DU COMBURANT ET PROCEDE DE CONDUITE D'UN TEL CUBILOT
Abstract:
(EN) The invention concerns a cupola for producing melt iron, comprising a vessel (2) for heating the materials to be smelted by burning combustion products inside the vessel (2), means (21) for loading the vessel with materials to be smelted, means (21) for supplying agents of combustion, means (10) for collecting fuel gases, means (12) for extracting fuel gases, means (7) for supplying oxidizing gas into the vessel and means (3) for evacuating the melt iron. The invention is characterised in that the oxidant-supplying means are formed by at least a suction nozzle (7); the extraction means (12) are adapted to set up relative to atmospheric pressure and relative to the fuel gas collecting means, a sufficient vacuum inside the vessel (2) for sucking up the oxidizing gas through the nozzle (7).
(FR) L'invention concerne un cubilot pour la production de fonte liquide, transformation de matières diverses du type comprenant une cuve (2) pour le chauffage des matières à fondre par combustion de combustible au sein de la cuve (2) de combustible, des moyens (21) de chargement de la cuve en matières à fondre, des moyens (21) d'apport du combustible, des moyens (10) de captation des gaz de combustion, des moyens (12) d'extraction des gaz de combustion, des moyens (7) d'entrée de gaz comburant dans la cuve et des moyens (3) d'évacuation de la fonte liquides matières transformées. Selon l'invention: les moyens d'apport de comburant sont formés par au moins une tuyère d'aspiration (7); les moyens d'extraction (12) sont adaptés pour établir par rapport à la pression atmosphérique et en relation avec les moyens (10) de captation des gaz de combustion, une dépression suffisante au sein de la cuve (2) pour aspirer le gaz comburant par la tuyère (7).
