Title:
METHOD OF IMPROVING CAPABILITY OF GLASS MELTING FURNACE USING CEILING-MOUNTED OXYGEN-FUEL BURNER
Document Type and Number:
Japanese Patent JP2007099620
Kind Code:
A
Abstract:

To improve melting speed of a glass forming batch raw material, glass quality and/or glass yield.

In a glass melting furnace 10 comprising: an air fuel burner; an upstream melting zone 27; and a downstream clarification zone 28 wherein the burner is mounted to a ceiling 22 in an upper part than a glass forming batch material in the melting zone 27, the glass forming batch material 30 is melted. A fuel and a combustion air stream to an air fuel burner are reduced, a gaseous oxidizing agent is passed into a burner 34 mounted at a ceiling, a gaseous fuel is poured to the burner 34, flames 36 are generated from the burner 34, reduced energy from the air fuel burner is substituted to give additional energy, the glass forming batch material 30 is made not to generate substantial disturbance, and flames 36 are controlled to have sufficient velocity in order to make heat transfer from the flames 36 to the glass forming batch material 30 into the maximum.
