Description

technical field [0001] The invention relates to an electrode device with a cooling and insulating structure, which belongs to the field of glass production pool kiln melting. Background technique [0002] While using fossil fuel flame to melt the glass, directly introduce electric energy into the molten glass to produce the "Joule effect", so as to achieve the purpose of auxiliary heating of the molten glass. The equipment that introduces electric energy is called auxiliary electric heating system, referred to as electric boosting system. [0003] While most electric boosting systems are installed to increase production, there are many furnaces where they are installed to improve glass quality, or to partially replace fuel to address operational issues. The electric boosting system can improve the quality of glass, especially in kilns using low calorific value fuels (such as gas). Furnaces equipped with electric boosting systems can increase production accordingly when the ...

Problems solved by technology

[0008] As we all know, during the process of melting glass, the temperature rise of the molten glass near the electrode tip is the highest, resulting in the strongest convection near the electrode tip; and because molybdenum is a good heat-conducting material, this causes the temperature rise of the bottom or wall material in contact with the electrode tip. High; the double effect causes chemical erosion and physical wear on the refractory material; especially the refractory material at the bottom or wall of the pool with good electrical conductivity, such as chromium oxide, will increase the electrical conductivity due to the increase of temperature, which will rapidly accelerate the electrode port material. damage
