摘要： A spacing arrangement for tubes of a reheater or superheater tube section uses a spacer bar that is sufficiently long to span a space across a plurality of tubes in the tube section. The spacer bar has a plurality of holes therein which are spaced apart by a selected spacing corresponding to a desired spacing between the plurality of tubes in the section. A plurality of sleeves is provided with one sleeve on adjacent tubes in the section. A tab is fixed to each sleeve and extends outwardly from the sleeve to which it is fixed so that the tabs of all the sleeves extend outwardly from a common plane containing all the adjacent tubes in the section. The tabs extend into respective holes in the spacer bar and fillet welds fix the tabs to the spacer bar adjacent the holes and at a location spaced from the sleeves.
摘要翻译：用于再加热器或过热器管部分的管的间隔布置使用足够长的间隔条跨越管部分中的多个管的空间。间隔杆在其中具有多个孔，其间隔开相应于该部分中的多个管之间的期望间隔的选定间隔。多个套筒在该部分中的相邻管上设置有一个套筒。一个突片固定到每个套筒上并从套筒向外延伸，固定到该套筒上，使得所有套筒的突片从包含该部分中的所有相邻管的公共平面向外延伸。突片延伸到间隔杆中的相应孔中，并且角焊缝将突片固定到邻近孔的间隔条和与套筒间隔开的位置。

摘要： The flow distribution baffle (14) is placed inside the bundle wrapper (7) of the steam generator, at its lower part,-near the steam generator tube plate. Passing through the flow distribution baffle (14) are openings (17, 18) for the passage of tubes of the steam generator bundle and feedwater. The flow distribution baffle (14) comprises a central zone (15) of more or less circular shape with, as its axis, the axis of the steam generator and a radius (R1) smaller than 40% of the internal radius (R) of the bundle wrapper (7), and a more or less annular peripheral zone between the central zone and the outer edge of the flow distribution baffle (14). In the central zone (15) the openings (17) for the passage of tubes and feedwater in the flow distribution baffle have a cross section (S1), the cross-sectional area of which is greater than the cross-sectional area of the cross section (S2) of the openings (8) for the passage of tubes and feedwater in the peripheral zone. The total surface area for the passage of feedwater in the peripheral zone (16) is greater than the total surface area for the passage of water in the central zone (15).
摘要翻译：流量分配挡板（14）放置在蒸汽发生器的束包装（7）的下部，靠近蒸汽发生器管板。通过流量分配挡板（14）是用于蒸汽发生器束和给水管的通过的开口（17,18）。流量分配挡板（14）包括具有或多或少圆形形状的中心区域（15），其具有蒸汽发生器的轴线作为其轴线，并且小于内部半径（R）的40％的半径（R1）束包装物（7），以及在分配挡板（14）的中心区域和外边缘之间的或多或少的环形周边区域。在中心区域（15）中，用于分流挡板中的管和给水通道的开口（17）具有横截面（S1），其横截面积大于十字的横截面面积在周边区域中用于通过管和给水的开口（8）的部分（S2）。供水周边区域（16）通过的总表面面积大于中央区域（15）内水通过的总表面面积。
