Among the wastes generated during nuclear power generation, flammable wastes such as ion exchange resins, grappling wastes and boric acid waste liquids are directly injected under a controlled oxygen atmosphere to be burned on molten glass to remove organic matter as an exhaust gas and to liberalize trace minerals. In order to prevent the waste from burning in the input furnace, a cooling water jacket was installed and different cooling temperatures were applied according to the type of waste. In addition, the oxygen supply tube is connected to the lower part of the supply line through the cooling water jacket so that the oxygen is evenly supplied through the annular throat around it as shown in FIG.
