连续加热炉;CONTINUOUS FURNACE

摘要

本发明之连续加热炉系具备：配置于炉本体内的一个或复数个密闭式气体加热器(110)，其具有供燃料气体燃烧的燃烧室，引导藉由燃烧室之燃烧而生成之废气的导出部，朝与被烧制物之运送方向正交之方向延伸并藉由燃烧室之燃烧或流通于导出部之废气的热而被加热且将辐射热传导至被烧制物之第1辐射面，供加热第1辐射面之废气流出的排气孔；以及一个或复数个排气传热部(214)，其系于炉本体内相对于密闭式气体加热器于被烧制物之运送方向一起设置，且具有与密闭式气体加热器的排气孔连通并藉由废气而被加热且将辐射热传导至被烧制物之第2辐射面(214a)，及在第2辐射面中之与运送方向正交之方向的一端(214b)侧或另外一端(214c)侧，促进从废气往第2辐射面之传热的传热促进部(216)。; and one or a plurality of exhaust heat transfer portion(s) (214) that are provided in parallel with the closed gas heater in the transportation direction of the burned objects inside the furnace body, and has a second radiation surface (214a) communicating with the exhaust opening of the sealable gas heater and being heated by the the exhaust gas and transfering radiant heat to the burned objects, and a heat transfer promoting portion (216) promoting heat transfer to the second radiating surface from the exhaust gas at one end (214b) or the other end (214c) of the second radiating surface in a direction perpendicular to of the transportation direction.
