Abstract

Un module de brûleur de l'invention comprend au moins trois ou quatre ou cinq ou six ou sept ou huit parois fonctionnelles qui délimitent au moins un premier espace fonctionnel et qui forment un corps de module. Le corps de module comporte au moins trois ou quatre ou cinq ou six ou six ou sept ouvertures de passage de gaz et au moins deux de ces ouvertures de passage de gaz sont reliées entre elles de manière communicante par le biais du premier espace fonctionnel. Au moins un moyen formant buse pourvu d'une ouverture de gaz combustible est formé dans une paroi supérieure du module de brûleur et est relié au premier espace fonctionnel de manière communicante par le biais d'un conduit de gaz. Le module de brûleur est fabriqué de manière générative.
