    摘要： A combustion chamber for an industrial gas turbine has thermal protective elements which are installed along the inner circumference of its casing. The thermal protective elements are cooled by cooling air which is added to the fuel in the region in front of a front casing section after the cooling. A brush seal is installed between the front casing section and the thermal protective elements, where the brush seal is configured in segments. The combustion chamber can be sealed against leakages of cooling air in all operating states of the combustion chamber.

    摘要： A seal (1) includes a first component (7) and second component (9), the first component including a first material having a high thermal and oxidation and wear resistance, and the second component (9) including a second material that is different from the first material and has a high spring load maintenance. The seal (1) is applied to a combustion chamber for a gas turbine, where the first component (7) extends between the casing wall of the combustion chamber and adjacent liner segments (4). The spring load of the second component (9) provides a seal also in the case of vibrations in a combustion chamber. The lifetime of the seal (1) is increased due to the individual materials, which are optimally chosen for the functions of high thermal and wear resistance and spring load maintenance respectively. The seal is further applied to the sealing between adjacent stationary blade platforms in gas turbines.

    摘要： The present invention relates to a sealing body for sealing an outer component with respect to an inner component, in particular for a combustion chamber of a gas turbine. The outer component has a passage opening, through which the inner component projects out of the outer component. In the installed state, the sealing body is arranged in the region of the passage opening, surrounds the inner component in a circumferentially continuous manner, bears in a circumferentially continuous manner, by means of an inner sealing zone, against an outer sealing surface of the inner component and bears in a circumferentially continuous manner, by means of an outer sealing zone, against an inner sealing surface of the outer component. The sealing body is produced by deformation from at least one metal sheet that is in strip form and is circumferentially continuous. The inner sealing zone and the outer sealing zone are formed at a profiled section of the sealing body along the entire circumference.

    摘要： Combustion driven pressure pulsations may limit the range of operating conditions where a modern gas turbine can operate with low emission and high efficiency performance. The control of acoustic vibrations has been consequently growing as an essential issue in gas turbine design, development and maintenance. The basic idea of the present invention is to use cooling air leakage through the gaps (7) of combustor liner segments (3;4) to get acoustic damping of combustion pulsations. The main component of the design is the sealing device (8) which covers the gap (7) between the two liner segments (3) and (4). The sealing device (8) collects in the plenum (9) some of the cooling air (6) flowing between the outer casing (1) and the inner liner structure (2). For this purpose the sealing device (8) is provided with openings (12) along the side walls (10) which allow the cooling air (6) to enter the plenum (9). In the plenum (9) the cooling air (6) is distributed along the gap (7) and discharged through openings (13), distributed along the top side (11) of the sealing device (8). The jets (18) discharged through the openings (13) achieve the additional effect to dampen acoustic pulsations in the combustion chamber (17).

    摘要翻译： 燃烧驱动的压力脉动可能限制现代燃气轮机可以以低排放和高效率运行的操作条件的范围。 因此，声波振动的控制作为燃气轮机设计，开发和维护中的一个重要问题而日益增长。 本发明的基本思想是使用通过燃烧器衬套段（3; 4）的间隙（7）的冷却空气泄漏来获得燃烧脉动的声阻尼。 设计的主要部件是覆盖两个衬垫段（3）和（4）之间的间隙（7）的密封装置（8）。 密封装置（8）在集气室（9）中收集在外壳（1）和内衬层结构（2）之间流动的一些冷却空气（6）。 为此，密封装置（8）沿着侧壁（10）设有允许冷却空气（6）进入增压室（9）的开口（12）。 在集气室（9）中，冷却空气（6）沿着间隙（7）分布并通过沿着密封装置（8）的顶侧（11）分布的开口（13）排出。 通过开口（13）排出的喷嘴（18）实现了抑制燃烧室（17）中的声波脉动的附加效果。

    摘要： The invention discloses a thermal turbomachine having at least one row of rotor blades (1). At least one first rotor blade (1) has a greater radial length than the others and at the blade tip (2) is equipped with a first abrasive layer (72). At least one rotor blade (1) which has a shorter radial length than the first rotor blade (1) is equipped with a second abrasive layer (71) at the blade tip (2). The first abrasive layer (72) has a better cutting capacity and a lower thermal stability than the second abrasive layer (71). During commissioning of the thermal turbomachine, the first abrasive layer (72) is in contact with the abradable layer of the stator (8), and during continuous operation of the thermal turbomachine the second abrasive layer (71) is in contact with the abradable layer of the stator (8).

    摘要： In order to avoid the “buckling” of multi-shell turbomachine casings during a cooling phase following the shutdown, it is proposed to provide means in order to suitably discharge warm medium which collects at a point of the casing cavity situated at the highest geodetic level. In an embodiment, it is proposed to allow the corresponding lines to open out in the stack of a power plant; the stack draft effect assists the flow even further. Regulating members are advantageously provided in the lines in order to shut off these lines during operation of the turbomachine on the one hand and in order not to arrange the flow through the casing cavities too intensively on the other hand.
