30 TPD Glass Industry Solution, Engineering, Melting Furance
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.
Physicochemical changes in each glass melting stage:
- Silicate forming
- Glass liquid forming
- Clearing
- Homogenization
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.
The defect of glass production is mainly due to the melting process, the melting quality has a close relationship with the quality of yield production, production cost, fuel combustion, furnace campaign, etc. It is important to ensure the physicochemical reaction of batched materials perform well during the whole melting process, and make sure the whole process is smoothly operated and for manufacturing high quality glass products.
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 |
Heating source
- Fired furnace
- The combustion fuel can be natural gas, heavy oil, diesel oil…… for this kind of furnace.
- Electric furnace
- Electricity is the fuel for this kind of furnace.
- Fired-electric furnace
- This kind of furnace is mainly using combustion fuel, electricity is used as a supplementary heating source.
3. Furnace structure
According to current fired furnace structure, it is mainly divided into four parts:
- Glass melting section
- Heat source supply section
- Waste heat recovery section
- Gas supply and waste gas exhaust
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.
Cooling section
It is a part for cooling and homogenization of the glass liquid, which is also an access for glass liquid distribution.
4. Furnace melting technology system
Reasonable melting technology is a system which could ensure a normal daily production. It will have an important function for high production, high quality, low consumption and furnace campaign.
Furnace melting technology includes temperature, pressure, bubbling, glass liquid level, fuel, reversing system etc.
5. Packing and transportation of refractory materials
