8tpd, Glass Furnace, Recuperative Furnace, Amber Bottle, Small Capacity
1. Brief Description
Glass is a special amorphous inorganic nonmetallic material. The main component is silicate, a non-crystalline solid with an irregular structure.
Glass furnace is a melting device, which is the most necessary and important equipment for the glass industry.
Recuperative furnace, with a narrow melting tank, is using a steel recuperator to pre-heat the combustion air.
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.

3. 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.
The flame goes out from the burner port. The shape, size and length of burner port will have a big effect for the speed, thickness, width and direction of the flame.
- Gas supply and waste gas exhaust
A gas supply and waste gas exhaust system is designed to ensure the continues, regular and efficient operation of the furnace, which includes double deck reversal unit, air and gas flue channel, middle flue channel, blower, main flue channel and chimney.
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 life span of furnace.
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.
There are two kinds of pressure distribution curves:
Gas flow pressure distribution: the whole gas flow pressure distribution, i.e. from gas in to gas out. Longitudinal pressure distribution: space pressure along the glass liquid process.
If the furnace is in a negative pressure situation, the cold air will be absorbed into the flame space and change the internal state of furnace, reduce the temperature and increase the energy consumption, even more, the internal temperature of the furnace will not distribute homogeneously. However, the pressure of the furnace cannot exceed the standard, if the pressure is too big, it will increase the energy consumption, shorten the life span of furnace, and the clearing and cooling of glass liquid will be affected.
