Abstract
La grille essentiellement disposée à horizontale est utilisée pour brûler un matériau combustible granulaire, p. ex. de la biomasse, qui est amenée sur une zone de chargement de la grille pendant qu'un flux d'air primaire provient de dessous de la grille. Celle-ci comprend un lit perforé ayant une surface supérieure inclinée vers le bas et convergeant vers une ouverture de décharge, où les produits de carbonisation sont concentrés lorsque le matériau combustible granulaire brûle pendant le fonctionnement. La grille comprend également un conduit allongé et perforé au bas pour recevoir les produits de carbonisation et positionné juste sous le lit. Le conduit de réception des produits de carbonisation est pourvu d'une extrémité d'entrée positionnée sous l'ouverture de décharge, et une extrémité de sortie qui est opposée à l'extrémité d'entrée. Le conduit de réception des produits de carbonisation est incliné vers le bas entre les extrémités d'entrée et de sortie. La présente concerne également une méthode de combustion d'un matériau combustible granulaire. Le concept proposé peut augmenter l'efficacité thermique globale d'un générateur de chaleur et réduire les émissions de gaz et de particules dans l'atmosphère.
