Abstract: A method and apparatus for heating extended steel products, such as pipes, tape, or wire products or rods following working such as rolling or extrusion, to a heat treatment temperature, normally to approximately 50 to 900 degrees Celsius. The heating takes place as a result of the product being fed through a burner that has a central through channel into which the product is fed. Fuel and oxidant are supplied through channels that are outside of the central channel and are supplied at such a rate that the combustion of the fuel takes place in front of an outlet opening of the burner head of the burner.

Abstract: Burner device (2) for an industrial furnace (1) comprising a channel (3) for fuel, a channel (4) for a first oxidant, an outlet (9) for flue gases, a control device (10) and a heat buffer (7), where the first oxidant and the flue gases alternatingly are led through the heat buffer (7). The invention is characterised in that a separate lancing device (6) is arranged to supply a second oxidant to the burner device (2).

Abstract: Method for measuring the local temperature in an industrial furnace (1) equipped with a burner (3), where at least two temperature sensors (21, 22) are arranged at different locations in the furnace (1). A virtual temperature measuring point is created by the association of each temperature sensor (21, 22) with a certain weight factor, in that the measurement values from each temperature sensor (21, 22) are weighted together using these weight factors in order to thus achieve a virtual measurement value, in that the weight factors at every given point in time are individually controlled based upon the momentarily emitted power of the burner (3), and in that the virtual measurement value in turn constitutes control parameter for the control of the emitted power of the burner (3).

Abstract: A method and a burner for combustion in a heating furnace of a fuel with an oxidant in the form of oxygen gas, wherein fuel and oxidant are supplied to a burner head. Fuel and oxidant, respectively, are injected via the burner head through at least two pairs of nozzles, wherein one nozzle pair is defined by a separate fuel nozzle and a separate oxidant nozzle. The nozzles of the nozzle pairs are uniformly distributed over the furnace-interior-facing surface of the burner and within the circumference of the burner head. An oxidant nozzle is provided on each side of a fuel nozzle.

Abstract: A method for providing uniform heat distribution within a furnace as well as decreasing the amount of NOx in the combustion products, when operating an industrial furnace having at least one conventional burner using air as the oxidant. At least one lance is connected with the furnace, and an oxidant including oxygen gas is flowed into the furnace through the lance to impinge against a flame issuing from the burner at a certain impingement point. The amount of oxygen supplied by the air supply to the burner together with the amount of oxidant issuing from the lance corresponds with the stoichiometric amount for a fuel supplied to the burner. At least 50% of the supplied oxygen for combustion is supplied through the lancing of oxidant, and the oxidant is flowed into the furnace through the lance at a velocity of at least 200 m/s.

Abstract: A method for heating metallic material, such as a slab or a billet, using at least one direct flame impingement burner. The heating power of the flame of the direct flame impingement burner is pulsated in cycles, so that the heating power is alternated between at least two different, predetermined heating powers. Each heating power is maintained during a certain predetermined time period. Some heating powers are lower than others, and the time periods are short enough so that the combination of the heating powers and their corresponding time periods results in not overheating the surface of the metal slab above a predetermined temperature during the time periods of the higher heating powers. The pulsated heating of the metallic material is interrupted when a certain stop condition is fulfilled, and the material is thereafter heated to another predetermined, final, homogenous temperature by the use of another, conventional heating method.

Abstract: A method for igniting a fuel/oxidant mixture in an industrial furnace. At least one fuel supply conduit and at least one oxidant supply conduit is provided, each conduit having an opening that opens on a side of the burner head that faces the furnace interior space. Fuel and oxidant are supplied to the burner head, and a light detector for detecting ultraviolet light, or other light wavelengths, is provided for detecting light that indicates the presence of a flame. A laser is positioned to emit a laser beam onto a point on the burner head adjacent the conduit outlets and to heat that point to a temperature exceeding the ignition temperature of the fuel/oxidant mixture. When the burner has ignited, the detector emits a signal to a control circuit that extinguishes the laser beam.

Abstract: A method for the manufacture of extended steel products. The steel product is initially contaminated by oils and by at least one of organic and inorganic particles that are suspended or dissolved in the oils. Following the shaping of the steel product by working but before the subsequent treatment of the steel product, burners emit exhaust gases that interact directly with the surface of the steel product. The burners are driven by an oxidant that contains at least 80% oxygen by weight, whereby oils that are present on the product are vaporized and combusted. The exhaust gases interact with the surface of the steel product with a speed that is sufficiently high to blow away organic and/or inorganic particles from the surface of the steel product.

Abstract: A method and apparatus relating to the combustion of a fuel with an oxidant in a heating furnace, wherein the fuel and the oxidant are delivered to a burner head. In a first method step fuel and oxidant are emitted from the burner head in close proximity to each other, so that combustion essentially takes place close to and at a small distance outward of the burner head, and until a temperature is reached in the furnace space that exceeds the spontaneous combustion temperature of the fuel. In a second method step the fuel and the oxidant are instead emitted from the burner head at a mutual distance apart, so that combustion takes place at a distance from the burner head corresponding to at least the diameter of the burner head and outward of the burner head.
