Title (EN) A STEAM GENERATOR FOR A CONVECTION OVEN
(FR) GENERATEUR DE VAPEUR POUR FOUR A AIR CHAUD
Abstract:
(EN) A storage generator for a convection oven through the oven chamber of which heated air is moved by means of a fan along a flow path in which the steam generator is positioned, comprises a heat-storage unit (11) having a plurality of elongate horizontal supports (16) for supporting ball-shaped heat-storage bodies (17) and means for spreading water over the heat-storage unit (11). Each support (16) includes a bottom wall having a plurality of polygonal apertures (23) which form seats for respective ones of the heat-storage bodies. The apertures (23), the size of which is substantially smaller than the largest cross-section of the heat-storage bodies, form flow passages through which water from overlying supports (16) is passed to the uppermost portion of the heat-storage bodies (17) of underlying supports.
(FR) Générateur de vapeur pour four à air chaud comprenant une chambre à travers laquelle de l'air chauffé est déplacé par un ventilateur situé le long d'un passage d'écoulement où se trouve placé le générateur de vapeur. Le générateur de vapeur se compose d'une unité de stockage de la chaleur (11) ayant une pluralité de supports horizontaux allongés (16) servant à supporter des éléments de stokage de la chaleur en forme de sphères (17) et un dispositif permettant de répandre de l'eau sur l'unité de stockage de la chaleur (11). Chaque support (16) comprend une plaque de base ayant une pluralité d'ouvertures polygonales (23) qui servent de siège pour chaque élément respectif de stockage de la chaleur. Les ouvertures (23), dont la taille est sensiblement plus petite que la plus large section transversale des éléments de stockage de la chaleur, forment des passages d'écoulement par lesquels passe l'eau provenant des supports se trouvant au-dessus (16) pour aller jusqu'à la partie la plus élevée des éléments de stockage de la chaleur (17) des supports se trouvant au-dessous.
