Le refroidissement d'eau à partir d'une partie du déversement de l'eau de refroidissement au sommet de la goulotte peut s'écouler de façon circonférentielle par rapport à la goulotte le long de la surface de la paroi interne, afin de former une membrane d'eau tourbillonnante. Le déversement de l'eau de refroidissement est réalisé de manière tangentielle, tel qu'on l'a vu dans la section horizontale de la goulotte, de manière que la membrane d'eau tourbillonnante aille dans la même direction que l'écoulement en vortex du gaz de gazogène dans la goulotte, ou dans la direction opposée à celui-ci. Le partie de déversement de l'eau de refroidissement peut utiliser un système de déversoir à partir d'un creux formé dans la périphérie extérieure de la goulotte ou un système de plaque guide comportant un canal d'écoulement annulaire formé dans la périphérie intérieure de la goulotte afin de permettre un écoulement direct.
