The invention relates to an arrangement and method for heating gases in a gas circulation duct in connection with continuously operated sintering. In the sintering furnace, hot gas is fed in from above the belt in order to sinter the material located on the belt, and part of the gas circulation duct is formed as a burning zone, a burning ring, where the gas is heated. The burner ring comprises at least one burner unit directed inwardly from the circumference of the gas circulation duct.
La présente invention concerne un agencement et un procédé de chauffage de gaz dans un conduit de circulation de gaz associé à un frittage en continu. Dans le four de frittage, du gaz chaud est alimenté au-dessus de la bande en vue d'effectuer le frittage du matériau qui s'y trouve, et une partie du conduit de circulation de gaz est constitué en zone de frittage, un anneau de combustion, dans lequel on réchauffe le gaz. L'anneau de combustion comporte au moins une unité de brûleurs orientée vers l'intérieur à partir de la circonférence du conduit de circulation de gaz.
