摘要:
The invention relates to a suspension smelting furnace comprising a reaction shaft (1), an uptake shaft (2), and a lower furnace (3), as well as a concentrate burner (4) for feeding reaction gas and fine solids into the reaction shaft (1) of the suspension smelting furnace. The concentrate burner (4) comprises a fine solids discharge channel (5) that is radially limited by the wall (6) of the solids discharge channel, a fine solids dispersion device (7) in the fine solids discharge channel (5), an annular reaction gas channel (8) that surrounds the fine solids discharge channel (5) and is radially limited by the wall (9) of the annular reaction gas channel (8), and a cooling block (10) that surrounds the annular reaction gas channel (8). The cooling block (10) is a component that is manufactured by a continuous casting method. The cooling block (10) is attached to the arch (11) of the reaction shaft (1) and the wall (9) of the annular reaction gas channel (8), so that the discharge orifice (12) of the annular reaction gas channel (8) is formed between a structure (13), which is jointly formed by the cooling block (10) and the wall (9) of the annular reaction gas channel (8), and the wall (6) of the solids discharge channel. The invention also relates to a concentrate burner (4) for feeding reaction gas and fine solids into the reaction shaft (1) of a suspension smelting furnace.
