Problems solved by technology

It has several disadvantages that are difficult to overcome: first, the thermal efficiency is low, and its heat loss accounts for about 70% to 80% of the total heat consumption, and the heat consumption per kilogram of glass liquid is above 1800 kcal; second, the melting rate is low, Generally below 1.5 tons/square meter per day; third, the gas temperature in the combustion space of the melting pool is high and the flow rate is high, which erodes the refractory material of the kiln faster and reduces the service life of the kiln
[0007] The reason is that this method of immersion combustion has problems that are difficult to solve

Abstract

A novel method for immersing, burning and melting molten glass by taking a vented fuel rod as a fuel is technically characterized in that oxidant gas is conveyed into a longitudinal through ventilation hole formed in the vented fuel rod (6), the vented fuel rod (6) immersed in the high-temperature molten glass is sequentially burned from front to back, enlightening compensation is continually obtained after the vented fuel rod is burned and lost, the vented fuel rod (6) and an enlightening compensation fuel rod (7) are connected without cutting off a gas source through a combined connecting device, the vented fuel rod (6) is pushed towards a furnace tank after burned and lost to a certain degree, the burned and lost portion of the vented fuel rod is compensated, the burning position of the vented fuel rod (6) is nearly unchanged in the molten glass, so that flame stably burns in the molten glass, the high-temperature gas generated by burning of the vented fuel rod stirs the molten glass, and most of heat is transferred to the molten glass and matched materials, so that glass materials are rapidly melted and homogenized.

Description

technical field [0001] Glass melting process. Background technique [0002] The melting of molten glass is the most important and core process in the glass manufacturing process. Its advantages and disadvantages play a decisive role in environmental protection, energy saving and emission reduction, and the manufacturing cost of glass. [0003] At present, the continuous melting of molten glass with fuel all adopts the method of surface heating. It has several disadvantages that are difficult to overcome: first, the thermal efficiency is low, and its heat loss accounts for about 70% to 80% of the total heat consumption, and the heat consumption per kilogram of glass liquid is above 1800 kcal; second, the melting rate is low, Generally, it is below 1.5 tons / square meter per day; the third is that the gas temperature in the combustion space of the melting pool is high and the flow rate is high, which erodes the refractory material of the kiln faster and reduces the service li...
