摘要： A crucible furnace comprises an enclosure having an outer casing 20 internally lined with thermally insulating material 21 surrounding but spaced from a crucible 22 so as 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 that burner flow in one direction along the flow path 23 and around the crucible 22 and leave the flow path through the burner 25 in flueing mode, whilst in the alternate cycle the hot combustion product gases from the firing burner 25 flow in the opposite direction along the flow path 23 and leave the flow path through the burner 24 in flueing mode.

摘要翻译： 坩埚炉包括具有外壳20的外壳，其内部衬有绝热材料21，隔热材料21围绕坩埚22间隔开，以便在坩埚周围形成圆形的流动路径23。 提供了一种气体燃料换向燃烧器系统，其具有两个具有相关联的热交换器42的燃烧器24和25.燃烧器24,25可交替地作为燃烧燃烧器和烟道操作。 当一个燃烧器（例如燃烧器24）被点燃时，来自该燃烧器的热燃烧产物气体沿着流动路径23沿着一个方向流动并且在坩埚22周围流动，并且使得流动路径通过燃烧器25处于通气模式， 循环来自燃烧燃烧器25的热燃烧产物气体沿着流动路径23沿相反方向流动，并且使得流动路径通过燃烧器24处于排气模式。
