30TPD End Fired Furnace Natural Gas Flint Container Glass
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 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.
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 a very complex process, it includes physical, chemical and physicochemical phenomena and reaction. These phenomena and reaction lead the mechanical mixed raw materials to complex melting glass liquid.
2. Furnace structure
Melting section
It is the part that melts the batch material and cleans and homogenizes the glass liquid. The upper space in the melting part is called the flame space, and the lower part is the melting tank.
The flame exits the burner through ports where preheated air is added to increase flame efficiency.
Dog house
The ingredients enter the furnace through the kennel, and the heat is transferred through the flame space into the glass liquid.
Air, gas access
After the heated air and gas exit the regenerator, they flow through this channel into the pre-chamber for mixing. This is also the channel through which the flue gas flows from the flame space into the regenerator.
pre-chamber
After the air and gas flow out of the channel, under the action of the vortex motion of the air flow and the diffusion and collision of molecules, the air and gas will mix before flowing into the furnace.
3. Furnace melting technology system
Furnace melting technology includes temperature, pressure, bubbling, glass level, fuel, reversing system, etc.
The temperature refers to the temperature of the furnace, not the temperature of the entire furnace. The temperature profile is from the melting tank through the length of the furnace.
The furnace pressure is the static pressure of the gas system, which is determined by the pressure distribution curve.
The stability of the shape and position of the bubbles is an important indicator to measure the melting performance, which will also affect the production capacity of the furnace and the quality of the molten glass.
