Abstract: A high power DC steam plasma torch system (S) includes a steam plasma torch assembly (1) wherein superheated steam (46) is used as the main plasma forming gas, thereby resulting in a very reactive steam plasma plume. The superheated steam (46) is injected internally directly into the plasma plume via a ceramic lined steam feed tube (25) for reducing condensation of steam before reaching the plasma plume. The superheated steam (46) flows through a gas vortex (16) which has tangentially drilled holes thereby resulting in a high speed gas swirl that minimizes electrode erosion. In the present steam plasma torch system (S), the plasma torch assembly (1) is ignited using an ignition contactor which is housed external to the plasma torch assembly (1). The superheated steam (46) is injected into the plasma plume using a water cooled steam vortex generator assembly (15).

Abstract translation: 高功率DC蒸汽等离子体焰炬系统（S）包括蒸汽等离子体炬组件（1），其中过热蒸汽（46）用作主等离子体形成气体，从而导致非常反应的蒸气等离子体羽流。 过热蒸汽（46）通过陶瓷内衬蒸汽进料管（25）内部直接注入到等离子体羽流中，用于在到达等离子体羽流之前减少蒸汽冷凝。 过热蒸汽（46）流过具有切向钻孔的气体涡流（16），从而导致高速气体涡流，使电极腐蚀最小化。 在本蒸汽等离子体焰炬系统（S）中，使用位于等离子体焰炬组件（1）外部的点火式接触器来点燃等离子炬组件（1）。 使用水冷蒸汽涡流发生器组件（15）将过热蒸汽（46）注入到等离子体羽流中。
