    • A TSL lance has an outer shell of three substantially concentric lance pipes, at least one further lance pipe concentrically within the shell, and an annular end wall at an outlet end of the lance which joins ends of outermost and innermost lance pipes of the shell at an outlet end of the lance and is spaced from an outlet end of the intermediate lance pipe of the shell. Coolant fluid is able to be circulated through the shell, by flow to and away from the outlet end. The spacing between the end wall and the outlet end of the intermediate pipe provides a constriction to the flow of coolant fluid to increase coolant fluid flow velocity therebetween. The further lance pipe defines a central bore and is spaced from the innermost lance pipe of the shell to define an annular passage, whereby materials passing along the bore and the passage mix adjacent to the outlet end of the lance. The end wall and an adjacent minor part of the length of the shell comprise a replaceable lance tip assembly.
    • TSL喷枪具有三个基本上同心的喷枪管的外壳,至少一个在壳体内同心的另外的喷枪管,以及在喷枪的出口端处的环形端壁,其连接壳体的最外和最内喷枪管的端部 喷枪的出口端与壳体的中间喷枪管的出口端隔开。 冷却剂流体能够通过外壳流出并远离出口端。 中间管的端壁和出口端之间的间隔提供了冷却剂流体的流动的收缩,以增加其间的冷却剂流体流速。 另外的喷枪管限定了中心孔并且与壳体的最内喷枪管间隔开以限定环形通道,由此沿着孔和通道混合的材料混合在喷枪的出口端附近。 端壁和壳体的长度的相邻小部分包括可更换的喷枪头组件。
