Industrial 80TPD Glass Melting Furnace System with Complete Refractory Lining for Glass Plants

1. Brief Description

The glass melting furnace is the core thermal unit in glass manufacturing, engineered to convert raw batch materials into a uniform molten glass suitable for forming operations. The feed mixture, precisely proportioned according to the target glass composition and blended with recycled cullet, is heated inside the furnace where melting, fining, and homogenization occur sequentially, yielding a high-quality glass melt ready for downstream processing. Glass production traces its origins back more than five millennia; early artisans melted batch in clay crucibles fired with wood, a technique that persisted for thousands of years. A major breakthrough occurred in 1867 with the introduction of the first continuous regenerative tank furnace fueled by coal in Germany. In the decades following 1945, glass melting technology underwent substantial evolution, leading to the development of various furnace configurations and advanced energy-saving measures.

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

The melting operation unfolds across five interconnected stages, each dependent upon the successful execution of the preceding one. Any deficiency in a single stage will cascade through the subsequent steps, ultimately degrading the final product quality.

4. Process Steps

Silicate forming
The raw batch undergoes thermal conversion into a sintered material consisting of various silicates and residual free silica.

Glass liquid forming
The sintered mass melts, with silicates and silica reacting further to produce a translucent glass melt filled with numerous entrained gas bubbles.

Refining (Clearing)
The glass melt is subjected to continued heating to lower its viscosity, promoting the escape of gaseous impurities and the elimination of macroscopic bubbles from the liquid bath.

Homogenization
The melt is held at sustained high temperature over a prolonged period, enabling diffusion-driven removal of compositional striae and ensuring uniform chemical and thermal properties throughout.

Cooling
The glass liquid viscosity is carefully adjusted downward to a level optimal for the intended forming technique.

5. Furnace Structure

Melting section
This primary zone is responsible for melting, fining, and homogenizing the batch. The upper region forms the flame space, while the lower region comprises the melting tank that contains the accumulating molten glass.

Dog house
Raw batch is charged into the furnace through the dog house opening, with thermal energy radiating from the flame space downward to the glass bath surface.

Air and gas access
Preheated combustion air and fuel gas are conveyed through this passage into the pre-combustion chamber, where they mix after leaving the regenerator.

Port
The port serves as a critical furnace element where fuel and preheated air meet for combustion. It simultaneously provides the inlet path for preheated air entering the furnace and the outlet route for flue gas exhaustion.

6. Furnace Melting Technology System

The melting technology system integrates various control parameters, including temperature profiling, pressure management, bubbling control, glass level monitoring, fuel delivery, and reversing logic.
