A furnace for melting inorganic and gasifying organic toxic and radioactive material comprising: - a frame; - a bowl-shaped housing for temporary enclosure of said material, which can be tilted around a substantially horizontal axis which intersects the housing at two points; - a supply opening through said housing that can be connected with a material supply for introduction of said material into said housing, said supply opening extending substantially coaxial with said horizontal axis through the housing at the site of the first of said two points; - a discharge opening through said housing for removal of molten material from said housing, the discharge opening being arranged in a wall of the housing so that at least part of said molten material can be removed from the housing via the discharge opening by tilting the furnace around said axis; - a gas outlet through said housing that can be connected with a gas discharge for removal of gasified material from said housing, said gas outlet extending substantially coaxial with said horizontal axis through the housing at the site of the second of said two points; wherein the furnace further comprises: - a plasma torch provided to melt and gasify the material introduced; - a first bearing disposed between the frame and the housing around each of said two points to mount the housing on the frame; - a second sealing bearing disposed within the supply opening configured to receive a part of said material supply to connect the supply opening hermetically to the material supply; and - a third sealing bearing disposed within the gas outlet configured to receive a part of said gas discharge to connect the gas outlet hermetically to the gas discharge. - a frame; - a bowl-shaped housing for temporary enclosure of said material, which can be tilted around a substantially horizontal axis which intersects the housing at two points; - a supply opening through said housing that can be connected with a material supply for introduction of said material into said housing, said supply opening extending substantially coaxial with said horizontal axis through the housing at the site of the first of said two points; - a discharge opening through said housing for removal of molten material from said housing, the discharge opening being arranged in a wall of the housing so that at least part of said molten material can be removed from the housing via the discharge opening by tilting the furnace around said axis; - a gas outlet through said housing that can be connected with a gas discharge for removal of gasified material from said housing, said gas outlet extending substantially coaxial with said horizontal axis through the housing at the site of the second of said two points; wherein the furnace further comprises: - a plasma torch provided to melt and gasify the material introduced; - a first bearing disposed between the frame and the housing around each of said two points to mount the housing on the frame; - a second sealing bearing disposed within the supply opening configured to receive a part of said material supply to connect the supply opening hermetically to the material supply; and - a third sealing bearing disposed within the gas outlet configured to receive a part of said gas discharge to connect the gas outlet hermetically to the gas discharge. - a plasma torch provided to melt and gasify the material introduced; - a first bearing disposed between the frame and the housing around each of said two points to mount the housing on the frame; - a second sealing bearing disposed within the supply opening configured to receive a part of said material supply to connect the supply opening hermetically to the material supply; and - a third sealing bearing disposed within the gas outlet configured to receive a part of said gas discharge to connect the gas outlet hermetically to the gas discharge.
