Definitions
- the invention relates to an ashing furnace for ashing organic substances, in particular of compounds which contain radioactive actinides chemically bound or are contaminated with chemical compounds of these actinides, with an ashing chamber which has a supply opening for oxygen-containing gas and an outlet opening for exhaust gas, and with a Filter body for the exhaust gas flow.
- the filter body of such an ashing furnace is usually installed in the exhaust pipe for the flue gas.
- This exhaust pipe can lead into a separate afterburning chamber of the incineration furnace, from which in turn an exhaust pipe branches off, which contains another filter body for cleaning the exhaust gas and which, seen in the direction of the exhaust gas flow, opens into the environment behind the filter body.
- the exhaust pipe with the filter body can also step directly into the open.
- the invention has for its object to prevent the distribution of harmful and dangerous substances originating from the organic substance throughout the ashing furnace and to localize accumulations of such dangerous and harmful substances only at very specific points in the ashing furnace.
- an ashing furnace of the type mentioned at the outset is characterized in that the filter body is pot-shaped, is arranged within the ashing chamber with its opening at the supply opening for oxygen-containing gas and on the side facing the supply opening for the oxygen-containing gas is a receiving space for which forms organic substances.
- Even in a low concentration in the orga-) * covering the supply opening for the oxygen-containing gas Dangerous and harmful substances present in African substances can be accumulated in the filter body in the form of oxides, removed from the ashing furnace together with the filter body and then processed further.
- the ashing chamber has a further inlet connection for oxygen-containing gas on the side of the filter body facing the outlet opening for exhaust gas and if an open one located inside the ashing chamber is located at the outlet opening for the exhaust gas Reaction tube is connected.
- a device for generating a pressure gradient which is directed from the side of the filter body facing the supply opening for oxygen-containing gas to the side facing the exit opening for exhaust gas. This allows the ashing furnace to be continuously loaded with organic substances to be ashes.
- An ashing furnace shown in the drawing has a hollow cylindrical ashing chamber 2.
- This ashing chamber 2 is closed at the lower end, while it has an inner flange 21 at the open upper end is provided.
- a hollow cylindrical filter body 1 is open at one end and lies there with an outer flange 22 on the outside on the top of the inner flange 21 of the ashing chamber 2, while the other end of the filter body 1 located within the ashing chamber 2 is closed.
- a cover which is provided with centering pins 10 which engage in the outer flange 22 of the filter body 1 and which is provided with a central opening 12 at which an open connection piece is located on the outside of the cover 11 13 is located, which is both the supply opening of the incineration chamber 2 for oxygen-containing gas and the supply opening for an organic substance to be incinerated.
- the feed opening of the incineration chamber 2 for oxygen-containing gas and its addition opening for the organic substance to be incinerated are therefore covered by the filter body 1.
- the ashing chamber 2 On the jacket, the ashing chamber 2 has electric radiators 5 on the outside.
- the ashing chamber 2 and the electric radiators 5 are inserted in a heat insulation container 6, which is closed with a heat insulation cover 7.
- This heat insulating cover 7 has a central passage 14 into which the socket 13 of the cover 11 engages.
- a further inlet connection 15 for oxygen-containing gas is passed through the inner flange 21 of the ashing chamber 2 and the heat insulating cover 7 and opens into the ashing chamber 2 between the filter body 1 and the jacket of the ashing chamber 2.
- an outlet connection 9 for exhaust gas is also guided, which merges within the ashing chamber 2 into an open reaction tube 4 reaching to the bottom of this ashing chamber 2, which extends between the filter body 1 and the jacket of the ashing chamber 2 is located.
- the outlet connection 9 is provided with a suction fan 16 for the exhaust gas.
- the filter body 1 advantageously consists of porous ceramic A1 2 0 3 or porous sintered metal, for example chromium-nickel steel.
- Comminuted organic waste substances for example cellulose, obtained in the production of plutonium-containing nuclear fuel are filled through the funnel 8 into a receiving space 3 formed by the filter body 1.
- the ashing chamber 2 is heated with the electric radiators 5 and the suction fan 16 is put into operation.
- Oxygen is introduced into the ashing chamber 2 through the inlet connection 15.
- Combustion air is sucked through the addition funnel 8 and the nozzle 13 into the receiving space 3 for the organic waste substances, in which these waste substances are incinerated.
- the gaseous combustion products pass through the pores of the filter body 1 and become afterburned in the space between the filter body 1 and the wall of the ashing chamber 2, so that exhaust gas containing water and carbon dioxide is released from the outlet nozzle 9 into the environment.
- Pu02 accumulates in powder form on the inside of the filter body 1, on which the feed opening of the ashing chamber 2 for oxygen-containing gas and the receiving space 3 formed by the connector 13 are located, and after the filter body 1 has been removed, it can accumulate in powder form removed and processed.
