Abstract

L'invention concerne un procédé d'amélioration des propriétés de produit de clinker lors de la combustion de farine crue dans un four à clinker ou à ciment, dans lequel des combustibles au moins partiellement inférieurs ou alternatifs sont employés. Selon le procédé, des déchets ou des combustibles inférieurs ou alternatifs contenant des substances organiques sont soumis à une dissociation thermique et à une réaction des produits de dissociation à l'aide d'énergie de rayonnement. Le gaz de produit ou de synthèse ainsi formé est acheminé vers les brûleurs de la combustion principale pour augmenter la température de flamme.
