Abstract:
1. A method of controlling thermal balance of a reaction shaft of a suspension smelting furnace, comprising using a concentrate burner that comprises a pulverous solid matter supply device for feeding pulverous solid matter into the reaction shaft, and a gas supply device for feeding reaction gas into the reaction shaft, the method comprising feeding into the reaction shaft pulverous solid matter, and feeding reaction gas into the reaction shaft for mixing reaction gas with pulverous solid matter to form a mixture by powdery solid matter and reaction gas in the reaction shaft of the suspension smelting furnace, wherein endothermic material is fed by the concentrate burner to constitute part of the mixture formed by powdery solid matter and reaction gas in the reaction shaft of the suspension smelting furnace, so that a mixture containing powdery solid matter, reaction gas and endothermic material is formed in the reaction shaft of the suspension smelting furnace; and wherein the endothermic material is a liquid cooling agent.
