    Abstract: Provided are a method and an arrangement for operating a metallurgical furnace. The method comprises a feeding step, and a temperature controlling step for controlling the temperature of a molten metal layer and a slag layer in a furnace space of the metallurgical furnace. The temperature controlling step comprises a first measuring step for measuring the slag temperature (Tslag), a second measuring step for measuring the slag liquidus temperature (Tslag, liquidus), and a calculating step for calculating a superheat temperature (Tsuperheat) by calculating the temperature difference between the slag temperature (Tslag) and the slag liquidus temperature (Tslag, liquidus). In case the calculated superheat temperature (Tsuperheat) is outside a predefined superheat temperature range (Tsuperheat set), the method comprises an adjusting step for adjusting to adjust the actual superheat temperature. Also provided are computer program products.

    Abstract: Provided is a burner such as a concentrate burner or a matte burner for feeding reaction gas and fine solids into a reaction shaft of a suspension smelting furnace. The burner comprises an annular fine solids discharge channel that is radially limited at the outside by a first annular wall and that is radially limited at the inside by a second annular wall. The annular fine solids discharge channel is configured to receive fine solids from a fine solids feeding arrangement and to create an annular flow of fine solids in the annular fine solids discharge channel. The annular fine solids discharge channel being provided with spreading means configured to be hit by the annular flow of fine solids and configured to even out particle distribution in the annular flow of fine solids.
