Abstract

Se describe un sistema y método para agregados tratados por calor, por ejemplo, un secador (10) de agregado del tipo que usa un quemador (12) y un tambor (14) rotatorio para cubrir agregado dentro de un sendero de flujo térmico. La invencion proporciona una pluralidad de mezcladores (42) que mezclan de manera segura combustible con un oxidante en una premezcla que es entregada a una cámara (56) de reaccion. La premezcla hace combustion y recircula dentro de la cámara (56) de reaccion para asegurar una combustion uniforme y completa, dando como resultado menos emisiones de contaminantes como el monoxido de carbono, componentes orgánicos volátiles, y oxidos de nitrogeno y también un menor estruendo de combustible. Esta combustion completa y uniforme da como resultado un perfil térmico uniforme dentro del tambor (14) rotatorio, dando como resultado un mayor rendimiento del agregado procesado y un consumo más eficiente de energía. La invencion también incluye una característica de "sintonizacion" para variar la entrega de combustible al quemador con el fin de evitar la vibracion resonante producida por una coincidencia de las frecuencias de combustion con la frecuencia natural de los sistemas de tratamiento.
