Abstract

本发明涉及单轴联合循环发电站(10)，其包括轴(30)，在轴(30)上按顺序定位有燃气涡轮(12)、中压蒸汽涡轮(14)、低压蒸汽涡轮(16)、发电机(20)、以及高压蒸汽涡轮(18)。

Description

单轴联合循环发电站轴布置
技术领域
本公开大体上涉及单轴联合循环发电站，并且更具体地涉及特别地适合于大容量涡轮的涡轮轴布置。
背景技术
在联合循环单轴发电站中，确定涡轮和发电机在轴上的最佳布置的关键参数涉及考虑轴扭矩、作为联合循环发电站的典型的构件的余热回收蒸汽发生器的布局和配置以及土建覆盖区(civil footprint)。
由于可获得更大型的燃气涡轮，因而可能将限制置于现有的离合器和轴承构件，因而可能导致对寻找备选的涡轮轴布置的新需要。
解决方案涉及将蒸汽涡轮列定位在燃气涡轮与发电机之间。该解决方案的限制是在于通过高压蒸汽涡轮而传输高扭矩。
另一解决方案涉及将发电机定位在燃气涡轮与蒸汽涡轮之间且将同步自换档离合器装配在燃气涡轮与蒸汽涡轮之间。对于某些安装，可能不可获得这样的离合器。
发明内容
提供了一种单轴联合循环发电站的涡轮布置，该布置至少能够提供大型高功率输出涡轮的备选的配置，其中由于对同步自换档离合器或发电机励磁机轴的机械限制，因而限制从轴布置穿过同步自换档离合器或发电机励磁机轴而传输的电力可能是期望的。
尝试借助于独立权利要求的主题来解决该问题。在从属权利要求中给出有利的实施例。
在一个方面，单轴联合循环发电站包括轴，燃气涡轮、中压蒸汽涡轮、低压蒸汽涡轮、发电机以及励磁机轴和高压蒸汽涡轮按顺序位于该轴上。
又一方面包括在燃气涡轮与中压蒸汽涡轮之间的轴上的第一推力轴承。还定位有在发电机励磁机与高压蒸汽涡轮之间的轴上的第二推力轴承，第二推力轴承需要发电机励磁机与高压蒸汽涡轮之间的柔性联轴器，以便补偿热膨胀。预期该方面要求用于启动蒸汽涡轮的辅助锅炉。
柔性联轴器能够被尺寸相对更小的同步自换档离合器连同用于启动中压蒸汽涡轮、低压蒸汽涡轮的相对更小的辅助锅炉所替换。
结合附图，本公开的其他方面和优点将从下文的描述变得显而易见，附图通过示例而图示本发明的示范性的实施例。
附图说明
通过由示例，参考附图而在下文中更全面地描述本公开的实施例，其中：
图1是根据本公开的示范性的实施例的单轴联合循环发电站的示意图。
参考标号
10 联合循环发电站
12 燃气涡轮
14 高压蒸汽涡轮
16 中压蒸汽涡轮
18 低压蒸汽涡轮
19 冷凝器
20 发电机
22 柔性联轴器
24、25 推力轴承
30 轴。
具体实施方式
现在，参考附图而描述本公开的示范性的实施例，其中相同的参考标号始终用于指相同的元件。在下文的描述中，为了解释，阐明许多具体细节，以提供对本公开的透彻的理解。然而，可以不利用这些具体细节来实践本公开，并且本公开不限于本文中所公开的示范性的实施例。
在整个描述中，蒸汽涡轮的压力设计限定其相对入口体积流量。照此，高压蒸汽涡轮 18具有比中压蒸汽涡轮 14低的相对入口体积流量，中压蒸汽涡轮 14继而具有比低压蒸汽涡轮 16低的入口体积流量。
图1示出单轴联合循环发电站10的示范性的实施例。在轴30上，存在按顺序定位于轴30上的燃气涡轮12、中压蒸汽涡轮14、低压蒸汽涡轮16、发电机20以及高压蒸汽涡轮18。在这方面，顺序意味着中压蒸汽涡轮14位于燃气涡轮12与低压蒸汽涡轮16之间，低压蒸汽涡轮16位于中压蒸汽涡轮14与发电机20之间，发电机20位于低压蒸汽涡轮16与高压蒸汽涡轮18之间，而燃气涡轮12和高压蒸汽涡轮18位于轴30的任一端。
在又一示范性的实施例中，推力轴承24在燃气涡轮12与中压蒸汽涡轮14之间定位于轴30上，而另一推力轴承25在发电机20与高压蒸汽涡轮18之间定位于轴30上。
在另一示范性的实施例中，柔性联轴器22在发电机20与高压蒸汽涡轮18之间和/或在发电机20与第二推力轴承25之间定位于轴30上。
虽然在本文中在被认为是最实用的示范性的实施例的示例中示出并描述本公开，但本公开能够以其他具体形式体现。例如，联合循环发电站可以包括不定位于单轴上的另外的蒸汽涡轮，并且因此，高压蒸汽涡轮18 可能是也可能不是定位于联合循环发电站中的最高压力的蒸汽涡轮。因此，目前公开的实施例在各个方面都被认为是说明的，而不是限制的。本公开的范围由所附权利要求指示，而不是由前文的描述指示，并且属于含义和范围及其等效物的范围内的所有的变化旨在被包括在其中。
