Oxygen-fuel burner for a glass melting furnace

Abstract:

A roof mounted oxygen-fuel burner for a glass melting furnace can produce a variable moving or sweeping flame in the furnace and can also vary the flame shape. The burner has a housing having an oxygen inlet pipe coupled to an oxygen chamber and a fuel inlet pipe coupled to a fuel feeding crossover block. The fuel feeding block feeds fuel to a nozzle fuel port while the oxygen chamber feeds a plurality of nozzle oxygen ports which oxygen port outlets are angled toward the centralized fuel port outlet. A rotating impeller over the oxygen ports has a partial opening that causes a variable moving or sweeping flame in the burner as the impeller rotates. The impeller is also raised or lowered to control the flow of oxygen to the plurality of oxygen port outlets to control the shape of the burner flame.
