Glass Processing, Melting Furnace For Glass Industry, Manufacture

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.

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.

Physicochemical changes in each glass melting stage:

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. 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.
