Abstract

LA INVENCION SE REFIERE A UN QUEMADOR DE GAS, PARTICULARMENTE PARA HORNOS DE CALENTAMIENTO DE PRODUCTOS SIDERURGICOS, QUE LLEVA UN CANAL CENTRAL (3) DE ALIMENTACION DE GAS COMBUSTIBLE, UN CANAL ANULAR (4) DE ALIMENTACION DE AIRE, CONCENTRICO, Y UN MORRO DE QUEMADOR (7), INSERTADO EN UN ALOJAMIENTO (9), CILINDRICO, DISPUESTO EN EL REVESTIMIENTO INTERNO DE LA BOVEDA DEL HORNO. EL MORRO DE QUEMADOR LLEVA: - UNA PRIMERA SERIE DE ORIFICIOS (10) PARA EL PASO DEL GAS, DISPUESTOS EN CIRCULO SOBRE UNA CORONA DE DIAMETRO MEDIO D1 Y EN COMUNICACION CON EL CANAL CENTRAL (3), SIENDO LOS ORIFICIOS (10) PARA EL PASO DEL GAS COAXIALES A LA DIRECCION AXIAL (X) DEL MORRO (7) DEL QUEMADOR, - UNA SEGUNDA SERIE DE ORIFICIOS (12) PARA EL PASO DE AIRE, DISPUESTOS EN CIRCULO SOBRE UNA CORONA DE DIAMETRO MEDIO D2 ALREDEDOR DE LOS ORIFICIOS (10) DE PASO DE GAS, Y EN COMUNICACION CON EL CANAL ANULAR (4) DE ALIMENTACION DE AIRE, ESTANDO LOS ORIFICIOS (12) DE PASO DE AIRE ORIENTADOS EN HELICE PARA CREAR UN FLUJO DE AIRE REMOLINANTE QUE PROVOCA UNA DEPRESION QUE ASPIRA EL GAS.
