Side burning device structure of float glass smelting kiln

Abstract

The invention discloses a side burning device structure of a float glass smelting kiln, comprising a side wall of the float glass smelting kiln, a burner guide hole is arranged on the side wall, an arc-shaped burner is arranged in the burner guide hole, and the central angle of the arc-shaped burner is 50 degrees-80 degrees. Since the arc-shaped burner is adopted and is inserted to the arc-shapedburner hole of a side burning hole brick and the side burning hole brick is inserted to the burner guide hole and is tightly attached to the wall of the burner guide hole, the invention solves the problems of sealing between the burner guide hole and the arc-shaped burner well, and meanwhile, due to the adoption of the arc-shaped structure of the adopted burner, the invention breaks through the traditional structure form so that the nozzle angle of the arc-shaped burner can be adjusted to the optimum spraying angle, thereby ensuring the spraying angle of flames, avoiding the situation of mutual interference of the flames at both sides, and then fuels can fully burn in the smelting kiln; and besides, the arc-shaped structure reduces the washing erosion of the flames on small furnace side walls.

Description

technical field [0001] The invention belongs to float glass production technology, and particularly relates to a structural device for realizing side firing production in a float glass melting furnace. Background technique [0002] At present, the commonly used combustion technology in float glass melting furnaces is generally bottom firing technology. When the fuel for melting glass is burned in the glass melting furnace, the fuel lance is usually placed under the combustion air. Low temperature regions exist, forming so-called black regions. The existence of the black zone reduces the coverage area of ​​the flame in the furnace and reduces the heat transfer effect. In addition, the contact area between combustion-supporting air and fuel during bottom combustion is relatively small, which makes it difficult to achieve uniform mixing, which reduces the fuel efficiency; especially for the gaseous natural gas fuel with relatively slow combustion speed, it cannot be uniformly ...

AI Technical Summary

Problems solved by technology

The existence of the black area reduces the coverage area of ​​the flame in the furnace and reduces the heat transfer effect

In addition, the contact area between combustion-supporting air and fuel is relatively small during bottom combustion, and it is difficult to achieve uniform mixing, which reduces fuel efficiency; especially for gas and natural gas fuels with relatively slow combustion speeds, the fuel cannot be mixed evenly and effectively, and the fuel is incompletely burned. Cause waste, not conducive to energy-saving and efficient production

However, the arc burners used in the existing side burners are all straight burners. After the straight burners are arranged on the side wall, the jet flames on both sides will interfere with each other, and the flame will interfere with the small furnace. Scouring erosion of side walls
