ABSTRACT:
The invention relates to a method for oxidizing the pulverous fuel of a furnace, advantageously a flash smelting furnace, by means of a burner, so that the oxidation takes place mainly owing to an effective mixing of two different combustion gases, pulverous fuel and possibly an extra fuel in the furnace space. The combustion gases are conducted into the furnace space in separate flows, so that oxygen is fed in through the center in an at least partly turbulent flow, and the air is fed around it in several separate flows. The invention also relates to a burner for mixing pulverous fuel and combustion gas and for burning them in the said furnace space.
