Abstract

Le procédé décrit sert à réduire la concentration de polluants dans un effluent provenant de la combustion d'un combustible charboneux. Ledit procédé consiste à introduire un premier agent de traitement dans l'effluent dans une première zone thermique, afin de réduire la concentration d'un premier polluant, et à introduire un second agent de traitement dans l'effluent dans une seconde zone thermique, afin de réduire la concentration soit du premier polluant soit d'un second polluant, les premiers et seconds agents de traitement étant introduits dans des conditions propres à réduire l'indice de pollution de l'effluent.
