Abstract

Dans les fours de réchauffage de l'art antérieur, les produits à chauffer traversent successivement une zone de préchauffage et une ou plusieurs zones de chauffage ou d'égalisation dans lesquelles les produits sont amenés pas à pas jusqu'à leur température finale déterminée pour traitement ultérieur. Afin de réduire le temps de séjour des produits dans l'espace du four et minimiser ainsi le risque de formation de tartre sur la surface du produit, la zone de préchauffage est, selon l'invention, équipée au moins dans certaines sections de brûleurs à oxygène sont conçus de telle sorte que les gaz de combustion qui en sortent forment une flamme qui, en fonctionnement du dispositif, atteint la surface des produits. Le contact direct avec la flamme augmente l'efficacité du transfert de chaleur et réduit ainsi le temps de séjour des produits.In the reheating furnaces of the prior art, the products to be heated pass successively through a preheating zone and one or more heating or equalization zones in which the products are brought step by step up to their determined final temperature for treatment. ulterior. In order to reduce the residence time of the products in the oven space and thus minimize the risk of scale formation on the surface of the product, the preheating zone is, according to the invention, equipped at least in certain sections with gas burners. oxygen are designed in such a way that the combustion gases coming out of them form a flame which, in operation of the device, reaches the surface of the products. Direct contact with the flame increases the efficiency of heat transfer and thus reduces the residence time of the products.
