Definitions
- the present invention relates to the field of radioactive waste treatment, and more particularly to an apparatus for measuring the temperature of a glass melting furnace.
- Radioactive waste vitrification is a technique for capturing radionuclides in a linkage of glass, which allows for a fairly stable treatment.
- radioactive waste is added to the glass melting furnace together with the glass to be melted, and then solidified to produce a glass solid containing radioactive waste nuclides.
- the temperature measuring device currently used in such a glass melting furnace is mostly a thermocouple, which is in direct contact with a measurement object to sense temperature. Because of this direct contact with the measurement object, the protective tube surrounding the thermocouple is exposed to high temperature glass melt, causing chemical corrosion, which is the main cause of shortening the life of the protective tube. Consequently, she is replacing the sheriffs at frequent intervals.
