Abstract

La présente invention concerne une installation d'extinction à sec du coke (1), dans laquelle du coke en ignition est chargé par la partie supérieure d'une chambre (3) dont la partie inférieure est en forme de cône, dans laquelle un gaz de refroidissement est soufflé depuis un moyen d'alimentation en gaz de refroidissement disposé dans la partie inférieure intérieure de la chambre, ce qui permet de refroidir le coke en ignition tombant dans la chambre, et dans laquelle le coke est évacué à travers un orifice d'évacuation de coke (12) formé dans la partie inférieure de la chambre. L'installation d'extinction à sec du coke est configurée pour qu'au moins un étage constitué d'une petite tête (45) soit prévu en dessous d'une tête principale (41). Cette tête principale fait partie d'une tête de projection (4), qui est disposée dans la partie inférieure de la chambre et possède un diamètre (D). La petite tête a un diamètre (d) plus petit que celui de la tête principale. Ainsi, la chute du coke dans la chambre est homogénéisée pour améliorer l'efficacité du refroidissement du coke.
