    • A seal is provided for preventing axial leakage through a radial gap between a stationary structure and a rotating structure. The radial gap is defined by an inner radial surface opposing an outer radial surface across the radial gap. The seal includes at least one land disposed on one of the inner radial surface and outer radial surface. At least one first tooth and at least one second tooth project from the other of the radial surfaces. The second tooth is shorter than the first tooth. At least one of the first tooth and second tooth, is configured to extend at an angle upstream. This angle is defined between a radial surface from which the first or second tooth projects and an upstream surface of the same tooth. The angle is less than or equal to about 80 degrees.
    • 提供密封件以防止通过固定结构和旋转结构之间的径向间隙的轴向泄漏。 径向间隙由跨越径向间隙的与外径向表面相对的内径向表面限定。 密封件包括设置在内径向表面和外径向表面中的一个上的至少一个区域。 至少一个第一齿和至少一个第二齿从另一个径向表面突出。 第二个齿比第一个牙齿短。 第一齿和第二齿中的至少一个构造成在上游以一定角度延伸。 该角度限定在第一或第二齿突出的径向表面与同一牙齿的上游表面之间。 该角度小于或等于约80度。

    • A system for removing moisture from a steam/water mixture engaging a stationary component of a steam turbine. The system includes an airfoil located within a flow path of a steam turbine. The airfoil is configured for removing moisture from a steam/water mixture traveling in the flow path. To this end, the airfoil includes a cavity in flow communication with the steam path through at least one inlet and outlet opening, near the leading and trailing edge of the airfoil, respectively. Moisture and steam are extracted from the surface through the inlet openings, the steam and water are separated in the cavity, the separated water flows towards the bottom end, and the dry steam flows through the outlet opening and returns to the steam path. The dry steam blowing out of the trailing edge reduces the size of secondary droplets, and thereby prevents erosion.
    • 用于从与蒸汽轮机的固定部件接合的蒸汽/水混合物中除去水分的系统。 该系统包括位于蒸汽轮机的流动路径内的翼型件。 翼型件构造成用于从在流动路径中行进的蒸汽/水混合物中除去水分。 为此,翼型件分别包括通过至少一个入口和出口开口与翼型件的前缘和后缘接近的与蒸汽通道流体连通的空腔。 水分和蒸汽通过入口从表面抽出,蒸汽和水在空腔中分离,分离的水流向底端,干蒸汽流过出口,返回到蒸汽通道。 从后缘吹出的干燥蒸汽减小二次液滴的尺寸,从而防止侵蚀。

    • A garment de-wrinkling device (1) comprises an enclosure (10) for moistening garments (20). An ironing board (40) and an adjacent standby area (41), which are both permeable to steam, are arranged on top of the enclosure (10). During operation of the device (1), the ironing board (40) and a steam iron (30) are used to iron garments (20) which have first been moistened inside the enclosure (10). In the process, steam released by the iron (30) penetrates the garments (20) and enters the enclosure (10) through the ironing board (40). In this way, both the garments (20) on the ironing board (40) and those inside the enclosure (10) are treated by means of steam that is released by the iron (30), and steam is used in an efficient manner. A pressed look is obtained in that the garments (20) are subjected to a moistening process and a subsequent steam ironing process.
    • 衣服消除皱纹装置(1)包括用于润湿衣服(20)的外壳(10)。 在外壳(10)的顶部设置有可渗透蒸汽的熨衣板(40)和相邻的备用区域(41)。 在设备(1)的操作期间,熨衣板(40)和蒸汽熨​​斗(30)用于熨烫首先在外壳(10)内被润湿的衣服(20)。 在此过程中,由熨斗(30)释放的蒸汽穿过衣服(20)并穿过熨衣板(40)进入外壳(10)。 以这种方式,熨衣板(40)上的衣服(20)和外壳(10)内的衣服都被熨斗(30)释放的蒸汽处理,并且以有效的方式使用蒸汽。 得到压制外观,其中衣服(20)经受湿润处理和随后的蒸汽熨烫过程。
