Abstract
EL METODO DEL PRESENTE INVENTO TIENE COMO CARACTERISTICA LA INCORPORACION DE UNA PLURALIDAD DE CAMARAS FRACCIONADAS (28,30,32,36,38,40) FORMADAS EN UN RECINTO CERRADO. SE INTRODUCEN FUEL PULVERIZADO Y AIRE EN UNA DE DICHAS CAMARAS (30,36) DURANTE EL ARRANQUE Y CARGA BAJA Y, AL INCREMENTARSE LA CARGA, EL FUEL Y EL AIRE SE INTRODUCEN EN LECHOS ADICIONALES (28,32,40). LA VELOCIDAD DEL AIRE SE CONTROLA PARA QUE SE ESTABLEZCAN INICIALMENTE LECHOS BURBUJEANTES FLUIDOS EN LAS CAMARAS Y, CUANDO LA CARGA SE INCREMENTA, LA VELOCIDAD DEL AIRE SE INCREMENTA TAMBIEN PARA ESTABLECER EN CADA CAMARA UN LECHO FLUIDO CIRCULANTE.
