    • A supporting structure for supporting the heat insulation elements of a steam generator of the type that is used in the primary circuit of nuclear power stations. The supporting structure utilizes hanging ties which are suspended from suspension pivots that are attached to the building which houses the steam generator. The hanging ties have the heat insulation elements attached thereto, and are integrated into the construction of the heat insulation elements. The steam generator consists of separate parts which are joined by weld seams that are subject to periodic inspection, and the heat insulation elements are made up of fixed parts which are suspended from the hanging ties and which form spaces therebetween for access to the weld seams, the spaces between the fixed insulating elements being sealed off by removable thermal insulating elements.
    • 一种用于支撑在核电站初级电路中使用的蒸汽发生器的隔热元件的支撑结构。 支撑结构利用悬挂在悬挂枢轴上的悬挂连接件,悬挂枢轴连接到容纳蒸汽发生器的建筑物上。 吊坠具有附接到其上的隔热元件,并且被整合到隔热元件的构造中。 蒸汽发生器由通过定期检查的焊缝接合的分开的部件组成,隔热元件由悬挂在吊带上的固定部件组成,并在其间形成用于接触焊缝的空间, 固定绝缘元件之间的空间由可拆卸的绝热元件密封。

    • An expansion joint is provided between the bottom supported tube walls and the top supported tube walls of a fluidized bed boiler furnace. The expansion joint includes an upwardly open trough having one side and a floor defined by bent portions of the bottom supported tube wall, and another side wall defined by a refractory lined steel plate. A knife edge or sealing projection is connected to an outwardly bent portion of the top supported tube wall and extends downwardly through the upward opening of the trough and into the spaced defined by the trough. The trough is filled with sand or other inert granular material which partially covers the knife edge. The knife edge is in the form of a tube wall with tubes having lower perforations. Fluidizing gas can be supplied into the knife edge to fluidize the sand around the lower end of the knife edge to permit movement of the knife edge in the sand as the top and bottom supported tube walls expand. A satisfactory seal is provided by maintaining a suitable height of the sand covering the knife edge.
    • 在底部支撑的管壁和流化床锅炉的顶部支撑的管壁之间设置有膨胀接头。 膨胀接头包括向上开口的槽,其具有由底部支撑的管壁的弯曲部分限定的一侧和底板,以及由耐火材料衬里钢板限定的另一侧壁。 刀刃或密封突起连接到顶部支撑管壁的向外弯曲部分并且向下延伸穿过槽的向上开口并进入由槽限定的间隔中。 槽中填充有部分覆盖刀刃的砂或其他惰性颗粒材料。 刀刃是管壁的形式,管子具有较低的穿孔。 可以将流化气体供应到刀刃中以使围绕刀边缘的下端的沙子流化,以允许顶部和底部支撑的管壁膨胀时刀刃在砂中移动。 通过保持覆盖刀刃的砂的适当高度来提供令人满意的密封。
