    • The present invention relates to a method pertaining to the combustion of a fuel with an oxidant in a heating furnace, wherein the fuel and the oxidant are delivered to a burner head. The invention is characterized in that in a first method step fuel and oxidant are caused to be emitted from the burner head (1; 10) in the close proximity of each other so that combustion will essentially take place close to and at a small distance outward of the burner head until there is reached in the furnace space a temperature that exceeds the spontaneous combustion temperature of the fuel; and in that in a second method step the fuel and the oxidant are caused to be emitted instead from the burner head (1; 10) at a mutual distance apart so that combustion will essentially take place at a distance from the burner head corresponding to at least the diameter of the burner head and outwards of the burner.
    • 本发明涉及一种在加热炉中燃烧燃料与氧化剂的方法,其中燃料和氧化剂被输送到燃烧器头部。 本发明的特征在于,在第一种方法步骤中,使燃料和氧化剂从燃烧器头部(1; 10)彼此靠近地排出,使得燃烧将基本上靠近和小的距离向外发生 直到在炉内达到超过燃料的自燃温度的温度; 并且在第二方法步骤中,使得燃料和氧化剂以相互间隔开的方式从燃烧器头部(1; 10)排出,使得燃烧将基本上发生在与对应于燃烧器头部 至少燃烧器头部的直径和燃烧器的外侧。

    • 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.
    • 本发明涉及一种用于调节反应气体的流速和粉状固体的分散空气的方法,该方法将反应气体和细碎的固体输送到悬浮熔炼炉的反应轴(6)上,以产生受控和可调节的悬浮液。 反应气体(8)从精细分散的固体物质流(5)周围进料到炉中,使得所述固体通过分散空气以朝向反应气体的取向分布。 通过在反应气体通道(13)中垂直移动并通过特殊形状的冷却块(12)的特殊形状的调节构件(10),对反应轴的反应气体的流速和排出方向进行无级调节, 围绕反应气体通道(13)并且位于反应轴的拱顶上。 反应气体的速度被调节为适合于位于反应轴拱(11)的底部边缘处的排出孔(14)中的期望气体量,并且从所述孔口将气体排放到 反应轴(6),并在其上形成具有粉状材料的悬浮液,并且根据粉末材料的供应来调节分散所述材料所需的分散空气。 本发明还涉及一种用于实现该方法的多重可调燃烧器。
