Natural Gas 80Tpd Glass Melting Furnace Heat Resistant Refractory Material Fused AZS

1. Brief Description

Glass melting furnace refers to the thermal equipment used in glass manufacturing to melt glass mixtures. Mix the powder prepared according to the glass composition and the added clinker (broken glass) at high temperature in the kiln to melt, clarify, and form a glass liquid that meets the forming requirements. Glass manufacturing has a history of 5000 years, and the manufacturing method of using firewood as fuel and melting glass materials in clay jars has continued for a long time. In 1867, the Siemens brothers in Germany built a continuous coal-fired tank furnace. After 1945, glass melting furnaces developed rapidly.

Glass melting is defined as the process in which raw materials are heated to temperatures between 1500 to 1700°C, undergoing chemical reactions to transform into molten glass within a furnace. This process involves continuous introduction of raw materials that mix with the molten glass, facilitated by natural convection and gas reactions.

2. Type of Glass Melting Furnace

· End fired regenerative furnace

· Cross fired regenerative furnace

· Recuperative furnace

· Full-Oxygen furnace

· Electric furnace

· Pot furnace

3. Scale of Furnace

• Small scale furnace -- Daily furnace capacity: below 50tons
• Medium scale furnace -- Daily furnace capacity: 50tons~150tons
• Large scale furnace -- Daily furnace capacity: 150tons plus

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.

          Silicate forming

The mixture is converted into a sintered material composed of silicates and silica

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.

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.

          Cooling

Adjust the viscosity to be suitable for forming

4. Furnace structure

• 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.

• Dog house

Batched materials feed into the furnace through dog house, the heat is transferred via flame space to the glass liquid.

• Air, gas access

The heated air and gas flow into the pre-combustion room for mixing via this access after they flow out of the regenerator.

• Port

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.

5. Furnace melting technology system

Furnace melting technology includes temperature, pressure, bubbling, glass liquid level, fuel, reversing system etc.
