Bubbling in a glass melting furnace is a mandatory fluxing measure in the glass melting process, and the bubbling technology has the advantages of economy, safety, easy operation and the like, so the bubbling technology is widely applied to various glass melting furnaces. The basic working principle is that the purified gas is bubbled to high-temperature glass liquid through one or more groups of bubblers arranged at specific positions at the bottom of a melting furnace to form bubbles which continuously move from bottom to top and are continuously amplified, and finally the bubbles are floated and broken on the glass liquid surface. When the colored glass is produced, the glass liquid at the bottom of the kiln is very viscous, the glass liquid around the bubbles can form a circular rotating circulation by adopting a bubbler technology, so that the heat energy transfer, exchange and absorption required by glass melting are promoted, and meanwhile, the blown bubbles take out tiny bubbles in the glass liquid to play a defoaming role.
