Abstract

UN QUEMADOR (10) PARA LA COMBUSTION DE UN COMBUSTIBLE MAS UNA MEZCLA DE AIRE COMPRENDE UNA TUBERIA DE TOBERA CENTRAL (16) QUE TIENE UNA SUPERFICIE INTERIOR (32) CON UNA PARTE QUE SE DESVIA HACIA AFUERA. UN TAPON AXIALMENTE MOVIL (38) ESTA COLOCADO EN EL INTERIOR DE LA TUBERIA DE TOBERA (16) E INCLUYE UNA PARED EXTERIOR (34) CON UNA SECCION DIVERGENTE QUE SE EXTIENDE EN EL INTERIOR DE LA SECCION DIVERGENTE DE LA TUBERIA DE TOBERA (16). MEDIANTE EL MOVIMIENTO AXIAL DEL TAPON (38), EL AREA DE CORTE TRANSVERSAL DEL ESPACIO ENTRE LAS SUPERFICIES DIVERGENTES AUMENTA Y DISMINUYE, DISMINUYENDO Y AUMENTANDO RESPECTIVAMENTE LA VELOCIDAD DEL COMBUSTIBLE MAS LA MEZCLA DE AIRE QUE PASA A TRAVES DEL ESPACIO DE TOBERA. ESTO REDUCE LA FORMACION DE NOX Y EL LARGO DE LA LLAMA PRODUCIDA POR EL QUEMADOR (10).
