摘要： The products (1) pass from a charging end (2) to a discharging end (3); at the discharging end side, the furnace exhibits a heating zone (4) equipped with air/fuel burners (41), possibly doped with oxygen, and, on the charging end side, exhibits a flue-gas recuperation or drainage zone (5) in which the flue gases are removed. At least one fuel body in the gaseous state is incorporated into the flue gases, and oxygen is introduced upstream of that possibly doped air/fuel burner (41) which is situated furthest upstream when referring to the direction of travel of the products (1), so as to burn the gaseous fuel body and thus raise the temperature in the recuperation zone (5). Possible use for heating steel-making products prior to rolling.

摘要： The invention relates to a method for heating a furnace comprising at least one burner capable of operating on an oxidant the oxygen content of which can vary; in a first period (P1) the burner is supplied with practically pure oxygen so as to provide a large amount of energy for heating, in a second period (P2) the burner is supplied with an oxidant, the oxygen content of which can vary between about 100% and 21%, in a third period (P3), the burner is supplied with an oxidant, the oxygen content of which is minimal, and which corresponds to a pilot period which requires only a small amount of heating energy. This method makes it possible to optimize the use of the furnace according to the desired thermal performance and oxidant operating costs.

摘要： Method of reheating metallurgical products, in which solid products, especially steel products, are reheated so as to bring them from a temperature substantially below 400° C. to a temperature of at least about 1000° C. by passing them through a furnace having an upstream zone in which the said products are preheated and a downstream zone in which the said products are brought to their final temperature on leaving the furnace, the downstream zone of the furnace being fitted with burners, at least some of which operate with an oxidizer which is air, the smoke (flue gases) generated by these burners flowing as a countercurrent to the products and preheating these products in the upstream preheating zone. According to the invention, at least one burner is placed in the upstream preheating zone of the furnace, this burner being fed with a mixture of oxidizer and fuel, the oxidizer containing more than 21 vol % and preferably more than 30 vol % oxygen.

摘要： Provided is a burner which includes a pipe having a free end region designed to be housed in a furnace quarl. The pipe includes one or more fuel feed ducts surrounded over part of their length by a sheath which defines an oxidizer feed channel and is fastened to a flange. A jacket is disposed around at least part of the length of the end region so as itself to be housed in the quarl and to define a feed channel for a second oxidizer between the jacket and the internal wall of the quarl. The jacket is fastened to a flange for securing to the quarl and the flange for the sheath is fastened to that for the jacket. The burner has particular applicability in industrial furnaces, especially for melting non-ferrous materials, for rehearing or for annealing.
