摘要： 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. The velocity of the reaction gas is adjusted to be suitable, irrespective of the desired gas quantity, in the discharge orifice (14) located at the bottom edge of the reaction shaft arch (11), and from said orifice the gas is discharged into the reaction shaft (6) and forms there a suspension with the pulverous material, and the dispersion air needed for dispersing said material is adjusted according to the supply of the pulverous material. The invention also relates to a multiadjustable burner for realizing the method.
