Abstract

Procédé de séparation de dioxyde de soufre des gaz de fumée d'un four, dans lequel en plus d'un combustible contenant du soufre (4) et d'un gaz contenant de l'oxygène (5) on introduit dans le four (1) un oxyde ou carbonate de calcium ou de magnésium pulvérulent (6) en excès par rapport au gaz de dioxyde de soufre formé dans la chambre de combustion, et on pulvérise séparément de l'eau (9) dans les gaz de fumée porteurs d'oxyde de calcium ou d'oxyde de magnésium (8) dans un réacteur (2) séparé de la chambre de combustion, de l'oxyde pulvérulent (6') pouvant etre amené directement dans les gaz de fumée quittant le four (1).Process for the separation of sulfur dioxide from the smoke gases of an oven, in which in addition to a fuel containing sulfur (4) and a gas containing oxygen (5) is introduced into the oven (1 ) a powdery calcium or magnesium oxide or carbonate (6) in excess with respect to the sulfur dioxide gas formed in the combustion chamber, and water (9) is sprayed separately in the smoke gases carrying calcium oxide or magnesium oxide (8) in a reactor (2) separate from the combustion chamber, powdery oxide (6 ') which can be brought directly into the flue gases leaving the oven (1).
