Electric Furnace

Brief Introduction

Electric furnace is advanced melting technology, which can produce stable and high quality glass liquid and has nearly no emissions.

Application

Electric furnace is especially suitable for small output but high quality glass production, such as Crystal Glass, Solar Glass, which is difficult to produce by normal furnace.

1. Brief Description

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.

2. 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. This is also an access for the flue gas to flow into the regenerator from the flame space.

• 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.

3. Furnace melting technology system

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

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.

Furnace pressure is the static pressure of the gas system, which is determinate by pressure distribution curve.
