Glass Melting Furnace, End Fired Furnace With Regnerator For Waste
Gas Recycle
1. Brief Description
Glass furnace is a melting device, which is the most necessary and
important equipment for the glass industry.
The end fired furnace is named by the longitudinal arrangement of
the burner port and the U shape of flame combustion route. At
present, the end fired furnace is more widely used in the glass
industry.
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.
2. Advantage
| 1 | Long Flame |
| 2 | High efficiency of heat utilization |
| 3 | Low energy consumption |
| 4 | Lower investment |
| 5 | Smal foot print |
3. Factors that influence the melting effects
| 1 | Characteristic of raw materials |
| 2 | Chemical compon |
| 3 | Material feeding method |
| 4 | Melting temperature |
4. Main sections of furnace
Normally, the semidiameter of working tank is equal to the width of
the melting tank, the depth of the working tank is less than
300mm-400mm of the melting tank.
Normally, the temperature of the dog house is about 1100°C~1400°C.
The batched materials will be pre-melted at this section.
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.
Flame space is a space which is combined with breast wall, crown,
and front and back gable wall. The fuel shall completely combust in
the flame space, in order to ensure enough heating of raw materials
melting and clearing.
Throat is a core section of the furnace, it will affect the quality
of glass and furnace campaign. The temperature of glass will reduce
when flowing through the throat.
The regenerator can heat the combustion air by exhausted gas coming
out from the furnace with the help of checker brick. It can not
only utilize the waste heat of gas, but also it can heat the
combustion air to a higher temperature, which is useful to increase
the working temperature. The waste gas can exhaust and the
combustion air can go into the access.
