1. A submerged combustion burner, comprising:
a central burner tube extending along a longitudinal axis and including a terminal end, the central burner tube defining an internal passage;
a heat pipe that surrounds and extends beyond the terminal end of the central burner tube, the heat pipe including a forward end, which is positioned axially beyond the terminal end of the central burner tube, and a rearward end, which overlaps with the central burner tube, the heat pipe comprising a working fluid sealed therein; and
an outer tube that surrounds the central burner tube and connects to the rearward end of the heat pipe, the outer tube and the heat pipe defining an annular space around the central burner tube;
wherein the internal passage of the central burner tube directs a flow of one of a fuel or an oxidant through the central burner tube while the annular space directs a flow of the other of the fuel or the oxidant.
