摘要： Apparatus (10) and a method for vitrifying hazardous waste includes a melting vessel (12) into which hazardous waste is introduced for heating by a heater (38), 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. Failure of the melting vessel (12) is detected by a sensor (48). A stirrer (39) mixes the material (18) during the heating. The containment vessel (46) is preferably hermetically sealed around the melting vessel (12) to contain gases and any melted material received from the failed melting vessel (12). The sensing of the failure is by a pressure change in the hermetically sealed chamber (58) or sensing of the presence of material received by the containment vessel (46) from the failed melting vessel (12) by electrical circuit type detection.

摘要： A method and apparatus for recycling scrap mineral fibers (42) having an organic binder coating in a highly stirred glass melter (16) wherein the organic binder coating is decomposed by applying heat. Carbon from the organic binder coating is oxidized on the surface of the glass melt (17). After oxidizing the carbon, the glass fibers are dispersed into the melt. Residual carbon may be oxidized after inclusion in the melt. Purified glass suitable for forming glass fibers is further processed by conventional glass fiber forming equipment. The method may also include the step of pre-processing the glass fiber scrap by shredding or pulverizing to facilitate feeding the glass fiber scrap to the highly stirred glass melt. The apparatus according to the present invention is preferably a stirred melter (16) having electrical joule effect heating. An impeller (22) in the glass melt stirs the melt at a high rate of speed to provide a draw down effect pulling fibers into melt.

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： A waste vitrification apparatus (10) having rotatable mixer impeller (16) functioning as a shaft electrode (60) and metallic vessel (14) functioning as a vessel electrode (62). A stream (12) of waste material and vitrifiable material are mixed and melted in the vessel (14) for vitrification. The waste vitrification method converts a feed stream (12) by mixing the feed stream into a glass melt (13) and melting glass batch of the feed stream (12) to form a foamy mass. The stream is dispersed by the impeller (16) to form a foam which is then densified in a settling zone (22), recovered through a spout (24) and solidified in storage containers. Means are provided to adjust the location of the mixing impeller (16) in the vessel (14) to change the depth of the settling zone (22). The impeller (16) is mounted on a drive shaft (18) having a recirculating coolant flow.

摘要： The mineral fiber forming apparatus (10) having electrodes (14) for heating heat softenable mineral material to form a molten mineral mass is disclosed. Organically-coated glass fiber scrap and cullet are supplied to a vessel (12) providing the heat softenable mineral material. An impeller (16) turbulently mixes the molten mineral mass dispersing batch into the molten mineral mass and converting water in the molten mineral bath to steam. Molten mineral material formed by the appartus (10) includes small seeds and gaseous occlusions. The molten mineral material is fed from an outlet port (24) in the vessel (12) to a rotary spinner (30) which forms hollow mineral fibers (32) having gaseous occlusions of between 1 % and 10 % by volume by centrifuging the molten mineral material.
