摘要：
Apparatus (10) and a method for vitrifying hazardous waste includes a melting vessel (12) in which a stirrer (38) mixes hazardous waste and any other necessary components for forming a glassy mixture upon heating while an electrical current is applied across the melting vessel and the stirrer to provide electrical current flow, and a metallic containment vessel (46) of the apparatus receives the melting vessel so as to receive and contain any material that exits the melting vessel upon failure. Any failure of the melting vessel (12) is detected by a sensor (48). The containment vessel (46) is preferably hermetically sealed around the melting vessel (12) to contain gases as well as any melted material received from the failed melting vessel (12). The sensing of the failure can be either by a pressure change in the hermetically sealed chamber (58) or by sensing of the presence of material received by the containment vessel (46) from the failed melting vessel (12) such as by an electrical circuit type detection.
摘要（中）：
设备（10）和用于玻璃化危险废物的方法包括熔化容器（12），其中搅拌器（38）在加热时混合危险废物和任何其它必要组分以形成玻璃状混合物，同时在熔融容器 和搅拌器以提供电流流动，并且该装置的金属容纳容器（46）接收熔化容器，以便接收并容纳在失效时离开熔融容器的任何材料。 通过传感器（48）检测熔化容器（12）的任何故障。 容纳容器（46）优选地围绕熔化容器（12）密封，以容纳气体以及从故障熔化容器（12）接收的任何熔融材料。 故障的检测可以是通过气密密封室（58）中的压力变化或通过感测由容器（46）从失效的熔化容器（12）接收的材料的存在，例如通过电路 类型检测。
