Abstract

UN INYECTOR OXIDANTE (1) PARA UN QUEMADOR QUE CONSTA DE UN CONDUCTO CENTRAL (2) Y UNA BOQUILLA (3) ACOPLADA AL MISMO Y QUE SE EXTIENDE AXIALMENTE SOBREPASANDO EL CONDUCTO CENTRAL (2). EL CONDUCTO CENTRAL SE COMUNICA CON UNA FUENTE DE OXIDANTE CON UN ALTO CONTENIDO DE OXIGENO, Y DURANTE SU FUNCIONAMIENTO, A ESTE OXIDANTE CON UN ALTO CONTENIDO DE OXIGENO SE LE HACE PASAR A TRAVES DEL CONDUCTO CENTRAL (2) Y A TRAVES DE UNO O MAS ORIFICIOS DE PASO (4) QUE HAY A TRAVES DE LA BOQUILLA (3) A MODO DE OXIDANTE PRINCIPAL EN UNA ZONA DE COMBUSTION (5) DONDE SE MEZCLA Y QUEMA CON COMBUSTIBLE QUE PREFERENTEMENTE ES ALIMENTADO A LA ZONA DE COMBUSTION CONCENTRICAMENTE ALREDEDOR DEL ELEMENTO DE SUMINISTRO DE OXIDANTE COMO POR EJEMPLO A TRAVES DE UN ELEMENTO DE SUMINISTRO DE COMBUSTIBLE (11). EL COMBUSTIBLE PUEDE SER CUALQUIER COMBUSTIBLE FLUIDO COMO POR EJEMPLO METANO, PROPANO O GAS NATURAL. EL CONDUCTO CENTRAL Y LA BOQUILLA PUEDEN ESTAR HECHOS DE CUALQUIER MATERIAL RESISTENTE A LAS ALTAS TEMPERATURAS COMO, POR EJEMPLO, INCONEL O ACERO INOXIDABLE. LA BOQUILLA TENDRA GENERALMENTE UNA FORMA ESENCIALMENTE HEMISFERICA. SE HACE PASAR UN OXIDANTE SECUNDARIO, QUE GENERALMENTE TIENE LA MISMA COMPOSICION QUE EL OXIDANTE PRINCIPAL, POR ENCIMA DE LA SUPERFICIE (6) DE LA BOQUILLA (3). GENERALMENTE EL OXIDANTE SECUNDARIO COMPRENDERA DE UN 5 A UN 15 POR CIENTO DEL OXIDANTE TOTAL UTILIZADO, A SABER, LA SUMA DE LOS OXIDANTES PRINCIPAL Y SECUNDARIO. SE HACE PASAR EL OXIDANTE SECUNDARIO DESDE EL CONDUCTO CENTRAL (2) A TRAVES DE UNAS LINEAS DE PASO O DESCARGA (7) QUE HAY EN UNAS INDENTACIONES DE LA BOQUILLA (8) DESDE DONDE FLUYE SOBRE LA SUPERFICIE DE LA BOQUILLA (3). SE PUEDE UTILIZAR CUALQUIER NUMERO ADECUADO DE ORIFICIOS (7) EN LA PUESTA EN PRACTICA DE ESTA INVENCION. EL OXIDANTE SECUNDARIO QUE FLUYE SOBRE LA SUPERFICIE DE LA BOQUILLA ACTUA A MODO DE BLINDAJE O BARRERA ENTRE EL CALOR DE LA ZONA DE COMBUSTION (5) Y LA BOQUILLA.
