In the float glass production process, clean gas with a certain pressure is blown upwards from the bottom of a glass melting furnace tank to float artificially formed bubbles upwards, so that glass liquid is stirred, and the purposes of promoting glass homogenization and increasing discharge amount are achieved. At present, the bubbling technology is one of the modern technical means of efficient energy-saving melting furnaces, plays a role in the production of colored glass, and has a particularly remarkable effect.
