  • Method for feeding and directing reaction gas and solids into a smelting furnace and a multiadjustable burner designed for said purpose
    Patent number: 6238457
    Abstract: The invention relates to a method for adjusting the flow velocity of reaction gas and the dispersion air of pulverous solids when feeding reaction gas and finely divided solids to the reaction shaft (6) of a suspension smelting furnace for creating a controlled and adjustable suspension. Reaction gas (8) is fed into the furnace from around a finely divided solid material flow (5), so that said solids are distributed with an orientation towards the reaction gas by means of dispersion air. The flow velocity and discharge direction of the reaction gas to the reaction shaft are adjusted steplessly by means of a specially shaped adjusting member (10) moving vertically in the reaction gas channel (13) and by means of a specially shaped cooling block (12) surrounding the reaction gas channel (13) and located on the arch of the reaction shaft.
