    • Disclosed herein is a nozzle tip that atomizes a liquid entering a vessel or reaction zone that contains circulating fluidized particulates where the nozzle tip comprises a first elongated slot that intersects with a second elongated slot to define a single orifice. The first elongated slot may have members protruding into it and the slots may intersect substantially orthogonally and bisect each other. The length of the minor axis of the first slot ranges form about 5% to about 50% of the length of the major axis of the first slot and the length of the minor axis of the second slot ranges form about 1% to about 10 % or the major axis of the second slot. This nozzle tip affords erosion reduction caused by the circulating fluidized particulates and therefore provides longer operational lifetimes for the nozzle tip.
    • 本文公开了一种喷嘴尖端,其使进入容器或反应区的液体雾化,该液体或反应区包含循环流化微粒,其中喷嘴尖端包括与第二细长槽相交以限定单个孔的第一细长槽。 第一细长槽可以具有突出到其中的构件,并且槽可以基本上正交地相交并且相互平分。 第一狭缝范围的短轴的长度形成约第一槽的长轴长度的约5%至约50%,第二槽的短轴长度形成约1%至约10% 或第二槽的长轴。 该喷嘴头提供由循环流化颗粒引起的侵蚀减少,因此为喷嘴头提供更长的操作寿命。
