    • A fluidized bed furnace includes a furnace housing having an outer shell. A furnace base and an outer top plate are secured to the respective lower and upper ends of the housing. A vertical retort has an opened upper end and an opened lower end. The retort is arranged in an opening formed in the outer top plate and extends downwardly into the center of the housing. Heat insulating material is disposed between the outer shell and the vertical retort. A retort base assembly is used to close the lower end of the retort. An upper support device is formed integrally with the retort at its upper end for supporting the vertical retort on top of the outer top plate so as to permit downward growth only during thermal expansion. A lower support device is interposed between the lower surface of the retort base assembly and the upper surface of the furnace base which supports substantially all the weight of the retort, the weight of the load of fluidizable media and the weight of a load of material to be heat treated.
    • 流化床炉包括具有外壳的炉壳。 炉底和外顶板固定在壳体的相应下端和上端。 立式蒸馏器具有敞开的上端和敞开的下端。 蒸馏器布置在形成在外顶板中的开口中,并向下延伸到壳体的中心。 绝热材料设置在外壳和垂直蒸馏器之间。 蒸馏器底座组件用于封闭蒸馏器的下端。 上部支撑装置在其上端与蒸馏器一体地形成,用于将外部顶板的顶部上的垂直蒸馏器支撑,以便仅在热膨胀期间允许向下生长。 下支撑装置设置在蒸煮基部组件的下表面和炉底的上表面之间,其基本上支撑蒸馏器的所有重量,可流动介质的负载重量和材料负载的重量, 进行热处理。

    • An apparatus for the continuous porcelain enameling of sheet ware including the combination, in succession, of a drying zone for the incoming ware either integral or separate, a pre-heating zone for the ware following the drying zone, a heating zone for the ware after the pre-heating zone or zones, in which the porcelain enamel coating is fused onto the surface, and a cooling zone or zones. Burner means are provided for introducing hot combustion gases into a serpentine tube radiant heater which is in the heating zone to heat the ware by means of flameless radiation. After leaving the heating zone, the hot combustion gases are directed into the final pre-heating zone where they transfer some of their heat to the ware passing through that zone. Finally, the combustion gases leaving the pre-heating zone are directed into the drying zone where they transfer heat by convection to remove moisture and slightly pre-heat the ware, whereupon the relatively cool combustion gases are exhausted from the drying zone.The present invention also contemplates a method for fusing a porcelain enamel coating onto a piece of ware by passing the ware sequentially through the aforementioned zones, passing combustion gases in countercurrent relationship to the movement of the ware, so that most of the usable heat in the hot combustion gases is used as it passes successively through the pre-heating and drying zone and the gases can be exhausted from the drying zone at a relatively low temperature.
    • 一种用于连续瓷搪瓷的设备,包括一体化或分离的进料干燥区域的组合,用于在干燥区之后的器皿的预热区域,用于器具的加热区域 其中瓷釉涂层熔合到表面上的预热区或区域以及冷却区或区域。 提供燃烧器装置用于将热燃气引入到加热区中的蛇形管辐射加热器,以通过无焰辐射来加热器皿。 在离开加热区之后,热的燃烧气体被引导到最终的预热区域中,在那里它们将一些热量转移到穿过该区域的器皿中。 最后,离开预热区的燃烧气体被引导到干燥区,在那里它们通过对流传递热量以除去水分并稍微预热器皿,于是相对较冷的燃烧气体从干燥区排出。 本发明还考虑了一种通过使器皿顺序地通过上述区域将瓷釉涂层熔合到一件器皿上的方法,使燃烧气体与器皿的移动成逆向关系,使得大部分可用的热量在 使用热燃烧气体,因为其连续通过预热和干燥区域,并且气体可以在相对低的温度下从干燥区域排出。
