Method for varying the hot point position for a flame in glass melting furnace involves varying fuel feed rates to concentric tubes in burner head

摘要

The method for varying the hot point of a flame in a glass or metal melting furnace involves varying the amount of fuel fed to the concentric tubes (1-3) of a multiple tube burner head. The burner head (Br) has central and peripheral fuel feeds with the amounts varied to vary the hot point. The ratio of fuel feed between the tubes is constantly adjusted.
