[en] An apparatus for incinerating radioactive wastes includes a furnace which has air inlet conduits and a flue gas outlet conduit and air heaters as well as blowers connected to the air inlets for forcing hot air into the furnace. The apparatus further has a feeding device connected to the charging end of the furnace for introducing liquid or solid wastes thereinto and a device which communicates with the discharge end of the furnace for removing solid reaction products from the furnace. In the flue gas conduit there is connected a plurality of flue gas filters each containing filter candles, a flue gas chamber and a mechanism for removing ashes from the flue gas chamber. The apparatus also includes a mixer section connected with the outlet of each flue gas filter and having a mechanism for mixing cool air with the flue gas filtered by the flue gas filters. Gas blowers connected to the output of the mixer section draw the gas from the apparatus. 18 Claims, 8 Drawing Figures

[en] The facility has a packing press which at least partly is contained within an alpha-tight box. The waste can be made compact and fixed in the 200 l iron-hooped drums by means of concrete. The press consists of two tie rods with a press cylinder and a press die acting downwards and fitting into the drum opening. The drum is standing on a pressing table fastened to the ends of the tie rods. The pressing table can be raised against the press die together with the drum. The lifting mechanisms to do this consist of hydraulic cylinders mounted at the lower end of the tie rods and whose piston rods, acting axially in extension of the tie rods, are hinged on the pressing table. In addition there may be mounted a bottom plate in the drum for reinforcement. (orig./PW)

[en] The solid radioactive wastes are locked into the furnace from above and the combustible liquid radioactive wastes are introduced into the inside of the furnace through a cooled pipe and are pulverized using compressed air. The device is characterized by a double tube in the upper section of the furnace, consisting of an inner pipe to introduce the liquid radioactive wastes into the inside of the furnace and an outer pipe for supplying compressed air for the pulverisation of the liquid radioactive wastes and for cooling the inner pipe.

[en] The column rotary press is mounted in a box and can be charged from the top. In the equipment packagable wastes contained in casks can be fed in without involving contamination, handled separately and, if necessary, crushed. All parts of the equipment are easy to exchange. The radioactive waste is fed in through a lock consisting of a double cover system. (orig./PW)

[en] The patent describes details of the removal device. This consists of a glove box with several glove openings, a tool lock, at least one window, a closing flap and a rough grid at the lower end. (PW)

[en] A glove box with several glove openings, at least one tool lock and at least one window, is situated above a post-combustion chamber. The glove box can be fixed or replaceable. (PW)

[en] The special configuration of the incinerator makes a greater throughput of solid waste possible without pretreatment and without sorting. The combustion of liquid waste is guaranteed in a safe and simple way and incineration can take place with the least consumption of energy. Easy repair or easy replacement of wear parts is guaranteed by dividing the furnace frame into three parts, by supporting the middle part on a platform and by the lower part of the middle part and the lower part of the frame projecting under the platform into a separate space. By placing the stack gas outlet in the middle section, the replacement of the upper section of the frame is made easier and corrosion problems in this section are reduced. This provides a longer service life of the upper section. (orig./PW)

[en] An incinerator for radioactive waste is described. Heat radiation from the incinerator into the loading device is reduced by the design of the slider with a ceramic plate and the conical widening of the pot, and also by fixing a metal plate between the pot and the floor. (PW)
