Abstract

Un método y una disposición para calcinar lodos de cal para obtener cal en un horno de cal. La cal fluye en contracorriente con relación a los gases de combustión desde un extremo de alimentación hacia un extremo de combustión y donde se utiliza como combustible un gas combustible, donde dicho gas se produce por medio de la gasificación de un combustible en presencia de aire de combustión en un gasificador. El aire de combustión para la gasificación se precalienta con el calor generado por la calcinación de los lodos de cal. La disposición se provee de un conducto entre el horno de cal y el gasificador para llevar aire desde el horno de cal al interior del gasificador como aire de combustión. Por lo menos una parte del aire de combustión para la gasificación se precalienta con el calor que se genera en la calcinación de los lodos de cal de manera tal que se lleva aire al enfriamiento de la cal que se obtiene en la calcinación y luego al interior del horno, desde el extremo de combustión de donde se toma el aire para la gasificación o a través de dicho extremo.
