Oxygen fuel burner for a forehearth system

A glass manufacturing system, comprising:

• a glass melting furnace,
• a forehearth system comprising a superstructure including a plurality of refractory bricks that frame a molten glass tank;
• a burner block comprising a refractory material within the superstructure above the molten glass tank including a discharge throat that extends to a distal end of the burner block;
• at least one oxygen fuel forehearth burner within the burner block having a long axis along a length direction, the oxygen fuel forehearth burner comprising:
• a burner body;
• a fuel pipe within the burner body having a fuel inlet for receiving fuel and a fuel outlet, and
• an oxygen pipe within the burner body having an oxygen inlet for receiving oxygen and an oxygen outlet, wherein the oxygen pipe is positioned coaxially outside the fuel pipe;
• wherein the fuel pipe extends beyond the oxygen pipe and beyond the burner body so that the oxygen first reaching the fuel and thus a flame when operating is delayed, and
• a glass forming apparatus coupled to receive molten glass after thermal processing performed by the oxygen fuel forehearth burner.
