10 To 50 Tpd Industrial Glass Furnace Customized 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.
