Abstract
SE PRESENTA UN PROCESO PARA LA INYECCION COMBINADA DE CARBON PULVERIZADO Y DE UN COMBURENTE GASEOSO EN UN CRISOL DE UN HORNO DE CUBA, EN PARTICULAR UN ALTO HORNO, A TRAVES DE UNA TOBERA DE VIENTO CALIENTE. AL NIVEL DE LA EMBOCADURA DE LA TOBERA EN EL CRISOL. SE INYECTA EL CARBON PULVERIZADO EN EL VIENTO CALIENTE BAJO FORMA DE UN CHORRO ANULAR HUECO, Y SE INYECTA EL COMBURENTE GASEOSO EN EL INTERIOR DEL CHORRO ANULAR HUECO. UNA LANZA PARA LA APLICACION DEL PROCESO COMPRENDE DOS TUBOS COAXIALES (16 Y 18) Y UN BLOQUE DE DISTRIBUCION PROVISTO DE UN ALISADO CENTRAL (52) PARA EL CARBON PULVERIZADO.
