Glass melting furnace
1. Brief Description
Glass melting furnace refers to the thermal equipment used in glass manufacturing to melt glass mixtures. Mix the powder prepared according to the glass composition and the added clinker (broken glass) at high temperature in the kiln to melt, clarify, and form a glass liquid that meets the forming requirements. Glass manufacturing has a history of 5000 years, and the manufacturing method of using firewood as fuel and melting glass materials in clay jars has continued for a long time. In 1867, the Siemens brothers in Germany built a continuous coal-fired tank furnace. After 1945, glass melting furnaces developed rapidly.
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 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 melting process is divided into five stages as following, each section has its inner connection, affecting each other. If one stage has imperfect performance, it will influence the next stage, and ultimately affect the quality of glass.
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.
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, the ripple eliminates by diffused function and homogenizes as a whole.
2. 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.
Batched materials feed into the furnace through dog house, the heat is transferred via flame space to the glass liquid.
The heated air and gas flow into the pre-combustion room for mixing via this access after they flow out of the regenerator.
It is an important part of furnace, it is the place where the fuel is mixed with the preheated air, also an access for the preheated air in to the furnace and exhausting the waste gas out.
3. Furnace melting technology system
Furnace melting technology includes temperature, pressure, bubbling, glass liquid level, fuel, reversing system etc.
| Item | Description |
| 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 | 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. |
