Abstract
Cet appareil comprend une trémie 8, 9 d'alimentation par gravité pour la matiere d'alimentation sous forme de particules; cette tremie est fixée sur le toit du four et communique avec l'intérieur de celui-ci. Pour empêcher les gaz du four de s'échapper dans l'atmosphère par cette trémie, il est prévu des tuyaux 10, 11 qui pénètrent dans la trémie pour y injecter de la vapeur, ou un autre gaz, afin d'empêcher les gaz sous pression contenus dans le four de s'échapper.
