Glass melting process with furnace and oxygen-fuel combustion over the air-fuel melting and combustion zone over the refining zone

摘要

"GLASS FUSION PROCESS WITH FUEL AND OXYGEN-COMBUSTIBLE COMBUSTION ON THE FUSION AREA AND AIR-FUEL COMBUSTION ON THE REFINING ZONE". Establishes a process and furnace for melting glass in which most of the combustion energy over the furnace melting zone is provided by combustion of oxygen-fuel while most of the combustion energy over the furnace refining zone is provided combustion of air-fuel. In many cases, it will be preferable to provide more than 70% and even including 100% of the combustion energy over the smelting zone through oxygen-fuel combustion and greater than 70% and up to and including 100% of the combustion energy over the refining zone through combustion of air-fuel. By properly refining the atmosphere of the combustion space by detonating oxygen-fuel and air-fuel, the present invention can result in an improvement in the productivity and quality of glass. The present invention can be applied to the construction of a new furnace or can be applied together with the existing air-fuel furnaces.
