Abstract
Un appareil de cuisson par convection comprend une cavité de four qui communique avec un ensemble canal d'aération renfermant un catalyseur. Le catalyseur comprend de multiples étages délimités par une première et deuxième structure en nid d'abeille, à distance l'une de l'autre. La première structure en nid d'abeille est disposée de manière à vaporiser initialement les sous- produits de charbon de cuisson, lesquels sont ensuite dirigés à la deuxième structure en nid d'abeille où les sous-produits vaporisés se fractionnent en dioxyde de carbone et en eau avant d'être évacués du catalyseur. Entre la première et la deuxième structure en nid d'abeille se trouve une brèche qui fonctionne de manière à créer une turbulence pour le débit de la vapeur à la deuxième structure en nid d'abeille.
