Abstract: L'invention concerne un procédé de combustion de charbon qui consiste à ajouter, avant la combustion, des sorbants liquides et/ou en poudre, permettant de capturer le soufre et d'autres composés indésirables qui apparaissent sous une forme du type céramique non réactive après la phase de combustion. On ajoute ainsi des poudres et/ou des sorbants alcalins à éléments multiples contenant de préférence des anions d'oxydation du type nitrates et nitrites, de préférence à base de calcium. Sous différentes variantes, les matériaux de remédiation, lorsqu'ils sont appliqués dans une poudre et/ou un liquide complexe contenant des éléments multiples, donnent une meilleure capture du soufre par rapport au résultat que donneraient ces matériaux sur une base individuelle. En mode de réalisation préféré, les sorbants contiennent des éléments qui réduisent au minimum ou abaissent le point de fusion de la cendre. Il en résulte une cohésion et une résistance de la cendre, moyennant quoi celle-ci s'accumule en quantité moins élevée sur la chaudière et le transfert de chaleur est amélioré.
