300 tpd, Glass Melting Furnace, Large Capacity Glass Melting Furnace
1. Brief Description
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.
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, the ripple eliminates by diffused function and homogenizes as a whole. The temperature of homogenization can be lower than the clearing stage.
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. This is also an access for the flue gas to flow into the regenerator from the flame space.
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.
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.
