Title:
TREATING METHOD AND DEVICE OF RADIOACTIVE GRAPHITE
Document Type and Number:
Japanese Patent JP3844327
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To quickly treat radioactive graphite by incineration together with inflammable miscellaneous waste by a compact device.
SOLUTION: In a secondary incineration chamber 2 connected to the outlet of melting furnace 1 for radioactive miscellaneous solid waste, lump of radioactive graphite is thrown in from a supply port 7 to incinerate with oxygen including gas in an oxygen-enriched burner 9 and the like. As the results, radioactive graphite is quickly incinerated and the exhaust gas of the melting furnace 1 is secondarily incinerated with the generated high temperature gas at least 1000°C. Part of high temperature gas is sent to the melting furnace 1 so as to be able to utilize as incineration air of flammables contacted in the inflammables.
