Customized, Small Size, Domestic Glass Melting Furnace, Construction
Construction Domestic 50 Tpd Industrial Glass Furnace
1. Brief Description
As early as the 4th century, the ancient Romans used glass for doors and windows.
Glass is a special amorphous inorganic non-metallic material. The main component is silicate, an amorphous solid with irregular structure.
Glass melting is the most important process in glass production. It is a molding process. Under high temperature heating, ingredients are evenly mixed to form qualified liquid without bubbles.
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.
Clearing
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.
Homogenization
The glass liquid is kept at high temperature for a long time, and the ripple is eliminated through the diffusion function, and it is homogenized as a whole. The homogenizing temperature can be lower than the clarification stage.
Glass melting is a very complex process, which includes physical, chemical and physicochemical phenomena and reactions. These phenomena and reactions lead to the formation of complex molten glass by mechanical mixing of raw materials.
2. Type of Furnace
Capacity
| 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
Melting section
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.
Dog house
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.
Pre-combustion room
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.
Temperature
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.
Pressure
Furnace pressure is the static pressure of the gas system, which is determinate by pressure distribution curve.
Bubbling
The stability of bubble shape and position is an important sign to measure the melting performance, and will also affect the production capacity of the furnace and the quality of liquid glass.
