摘要：A crucible furnace comprises an enclosure having an outer casing 20 internallylined with thermally insulating material 21 surrounding but spaced from a crucible 22 soas to define a circular flow path 23 around the crucible. A gas fuelled reversing burner

system is provided having two burners 24 and 25 each with an associated heat

regenerator 42. The burners 24,25 are operable alternately as firing burners and as flues.When one burner, say burner 24, is firing, the hot combustion product gases from thatburner flow in one direction along the flow path 23 and around the crucible 22 and leavethe flow path through the burner 25 in flueing mode, whilst in the alternate cycle the hotcombustion product gases from the firing burner 25 flow in the opposite direction alongthe flow path 23 and leave the flow path through the burner 24 in flueing mode.
