1. Brief Description
Glass was used for windows and doors by the Ancient Romans as early as the 4th century.
Glass is a special amorphous inorganic nonmetallic material. The main component is silicate, a non-crystalline solid with an irregular structure.
Glass melting is the most important process in glass production, it is a forming process where the batched materials form a qualified liquid evenly with no bubbles under high temperature heating.
Glass liquid forming
In this stage, the sinter will be melting and the silicate and SiO2 in sinter will change to flint glass liquid with a plenty of bubbles. However, its chemical components and character are not even.
The glass liquid is continuously heated, and its viscosity is reduced with plenty of gaseous sundries released, which should eliminate the visible bubbles with the pool of liquid.
The glass liquid is kept at high temperature for a long time, the ripple eliminates by diffused function and homogenizes as a whole. The temperature of homogenization can be lower than the clearing stage.
Glass melting is a very complex process, it includes physical, chemical and physicochemical phenomena and reaction. These phenomena and reaction lead the mechanical mixed raw materials to complex melting glass liquid.
|Small scale furnace||Daily furnace capacity: below 50tons|
|Medium scale furnace||Daily furnace capacity: 50tons~150tons|
|Large scale furnace||Daily furnace capacity: 150tons plus|
3. Furnace structure
It is the part which melts batched materials and Clearing and homogenizes glass liquid. In the upper space of the melting section is referred to as the flame space, the lower part is melting tank.
The flame comes from the burner through the port, which feds in preheated air to increase the flame effiency.
Batched materials feed into the furnace through dog house, the heat is transferred via flame space to the glass liquid.
Air, gas access
The heated air and gas flow into the pre-combustion room for mixing via this access after they flow out of the regenerator. This is also an access for the flue gas to flow into the regenerator from the flame space.
After the air and gas flow out from the access, under the airflow vortex motion, and molecule diffusion and collision, the air and gas will mix before flowing into the furnace.
4. Furnace melting technology system
Furnace melting technology includes temperature, pressure, bubbling, glass liquid level, fuel, reversing system etc.
The temperature means the temperature the of melting tank, not the whole furnace. The distribution of temperature is from the melting tank through the length of the furnace.
Furnace pressure is the static pressure of the gas system, which is determinate by pressure distribution curve.
Stable shape and position of bubble are an important sign to estimate the melting performance, which will also affect the production capacity of furnace and quality of glass liquid.
