Title (EN) TUYERE FOR TORCH GUNITE
(FR) CUILLERE POUR TORCHE A GUNITE
Abstract: front page image
(EN)A tuyere for torch gunite comprises a water-cooled casing consisting of two pipes (1 and 2). Inside the water-cooled casing are mounted coaxially pipes (4) for supplying a powder like mixture of refractory material and a fuel and pipes (3) for supplying the oxigen. At the outlet ends of the said pipes (3 and 4) along their walls are mounted nozzles (5) for supplying the powder-like mixture of the refractory material and the fuel and nozzles (6) for supplying the oxygen, all combined in pairs and located coaxially in each pair. The face of each nozzle (5) for supplying the powder-like mixture of the refractory material and the fuel is placed below the face of each corresponding nozzle (6) for supplying the oxygen at a distance equal to 1 to 5 internal diameters of the nozzle (5) for supplying the powder-like mixture of the refractory material and the fuel. The walls of at least one nozzle (5 or 6) of each pair have, fully or partially, a form different from that of a cylinder.
(FR)Une cuillere pour torche a gunite comprend un corps refroidi a l"eau constitue de deux cubes (1 et 2). A l"interieur du corps refroidi a l"eau sont montees des canalisations coaxiales (4) d"alimentation en un melange pulverulent d"un materiau refractaire et en un combustible, et des canalisations (3) d"alimentation en oxygene. Aux extremites de sortie des canalisations (3 et 4) sont montes, le long de leur paroi, des ajutages (5) pour l"alimentation en melange pulverulent en materiaux refractaires et en combustibles et des ajutages (6) pour l"alimentation en oxygene, ces ajutages etant combines par paire et situes coaxialement dans chaque paire. La face de chaque ajutage (5) d"alimentation en melange pulverulent de materiau refractaire et en combustible est placee sous la face de chaque ajutage correspondant (6) d"alimentation en oxygene a une distance de 1 a 5 fois le diametre interne de l"ajutage (5) d"alimentation en melange pulverulent de materiaux refractaires et en combustibles. Des parois d"au moins un ajutage (5 ou 6) pour chaque paire ont, entierement ou partiellement, une forme differente de celle d"un cylindre.
