Abstract
Mejoras introducidas en el objeto de la patente principal número 425.605 por procedimiento e instalación para el tratamiento térmico de material finamente granulado, tal como cemento crudo en polvo, con un horno rotativo y un precalentador formado de un número de etapas de ciclón, a través de las que fluyen los gases de escape desde el horno rotativo, en que en la tubería de gas, que conduce desde el horno rotativo a la etapa de ciclón más baja, termina allí una línea de alimentación de material procedente de la siguiente etapa de ciclón, debajo del material de esta línea de alimentación está dispuesto un miembro distribuidor, para romper la corriente de material y, debajo del miembro distribuidor, la línea de combustible se abre dentro de la tubería de gas, de manera que forme una zona de combustión extendiéndose sustancialmente sobre la entera sección transversal de la tubería de gas y haciéndose pasar más de una vez, por lo menos por una porción sustancial del material, como en la patente principal nº 425.605.
