Abstract

PROCEDIMIENTO PARA LA INYECCION EN UN ALTO HORNO DE GASES REDUCTORES SOBRECALENTADOS PRODUCIDOS A PARTIR DE COMBUSTIBLES SOLIDOS. CONSISTE EN INYECTAR, AL NIVEL DE LAS TOBERAS PRINCIPALES, GASES REDUCTORES SOBRECALENTADOS A UNA TEMPERATURA COMPRENDIDA ENTRE 1.500 Y 2.800 GRADOS, CONTENIENDO ESTOS GASES PRINCIPALMENTE CO, H Y, EVENTUALMENTE, N , CO Y H O. DICHOS GASES REDUCTORES SE OBTIENEN A PARTIR DE UN COMBUSTIBLE SOLIDO, PREFERENTEMENTE SECO Y FINAMENTE MOLIDO, INYECTADO EN PROPORCIONES ADECUADAS EN UN REACTOR EN EL QUE ES GASIFICADO EN CONTACTO CON UN AGENTE OXIDANTE TAL COMO AIRE, VIENTO SOBREOXIGENADO O INCLUSO GASES RECIRCULADOS DE DICHO REACTOR, QUE POSEEN UN CONTENIDO SUFICIENTE DE CO .
