10 Ton Per Day, Small Capacity, Recuperative Furnace, Glass
1. Brief Description
Glass is a special amorphous inorganic nonmetallic material. The
main component is silicate, a non-crystalline solid with an
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.
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.
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. 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.
4. 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.
