Abstract

Procédé d'alimentation en continu et régulière de particules solides dans un appareil sous pression. Selon l'invention, le transport des particules à partir du réservoir fermé 1 s'effectue dans une première zone 11 (vis 16) au moyen d'un dispositif d'extraction réglable (vis 16), dans une seconde zone 12 au moyen d'un gaz vecteur à écoulement lent, et dans une troisième zone 14 au moyen d'un gaz propulseur à écoulement rapide. Application : foyers à charbon pulvérulent.
