Abstract
L'invention concerne l'amélioration du foncttionnement des dispositifs de précipitation électrostatique des poussières de gaz provenant de fours rotatifs. Avant de broyer puis de brûler le combustible solide (charbon), on lui ajoute une faible proportion d'au moins un composé alcalin. Application : amélioration de la purification des gaz provenant de fours rotatifs brûlant du calcaire pour pro uire de la chaux (pour ciment).
