Abstract

La cheminée disposée au-dessus du réservoir collecteur de granulat et destinée à capter les vapeurs et gaz produits pendant l'opération de granulation est réalisée sous la forme d'un condenseur (9), comportant un registre (12) dans un conduit d'extraction (13). Des gicleurs d'arrosage (10) sont prévus pour arroser la vapeur et les gaz venant de la réserve d'eau (6) et, sur l'extrémité de tete (15) du condenseur (9), est disposée une conduite de retour (14) pour ramener le gaz résiduel à l'injecteur (4) au moyen duquel de l'eau est injectée dans le jet de laitier arrivant par une goulotte (2).
