Small Scale Automatic Industrial Glass Furnace 50 Tons Capacity
1. Industrial Glass Furnace Brief Description
Silicate forming
In this stage, the components of batched materials will produce a physicochemical solid phase reaction during heating process, in which the gaseous products will be released from the batched materials and produce a new opacity sinter ultimately, which is formed by silicate and SiO2.
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.

3. Industrial Glass Furnace structure
According to current fired furnace structure, it is mainly divided into four parts:
- Glass melting section
- Heat source supply section
- Waste heat recovery section
- Gas supply and waste gas exhaust
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.
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
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 furnace campaign.
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
Stable shape and position of bubble are an important sign to estimate the melting performance, which will also affect the production capacity of furnace and quality of glass liquid.
