Abstract

Procedimiento para producir aglomerados sintéticos a partir de subproductos de combustión que comprende: (a) aporte de subproductos de combustión que contienen azufre; (b) aporte de finos secos de recirculación que contienen hidróxido cálcico (Ca(OH)2); (c) aporte de un material que contiene aluminio; (d) aporte de agua; (e) mezclado de los finos secos de recirculación que contienen hidróxido cálcico, los subproductos de combustión, el material que contiene aluminio, y el agua para formar una mezcla de alimentación; entonces (f) aglomerar la mezcla de alimentación en un producto aglomerado; entonces (g) combinar el producto aglomerado con los finos de endurecimiento que contienen óxido de calcio produciendo una mezcla combinada; entonces (h) endurecer la mezcla combinada para conformar los aglomerados y crear los finos secos de recirculación para la recirculación, durante lo cual la humedad de la mezcla combinada hidrata de forma exotérmica el óxido de calcio de la mezcla combinada para formar un material que contiene hidróxido cálcico seco, y proporciona de forma autógena todo el calor necesario para el endurecimiento, no siendo necesario aporte de calor externo; entonces (i) separar los aglomerados y los finos secos de recirculación; y (j) recircular los finos secos de recirculación que contienen hidróxido de calcio a la etapa de mezclado.
