本发明涉及一种包括蒸汽轮机(2)和过载阀(12)的装置(1),其中过载阀(12)与新鲜蒸汽阀(7)相对置地设置,并且新鲜蒸汽部分地流过流动通道并且部分地经由过载阀(12)流入到过载流入区域(11)中。

Description

到蒸汽轮机中的过载导入
技术领域
本发明涉及一种包括蒸汽轮机和连接部的装置,所述蒸汽轮机具有双壳式的壳体,所述壳体包括外壳体和设置在所述外壳体中的内壳体,所述连接部引导穿过外壳体,其中连接部设有一对连接口,所述连接口由第一连接口和第二连接口形成,所述第一连接口和第二连接口在内壳体上构成,所述装置还包括用于将蒸汽引导到内壳体中的第一阀,其中第一阀与第一连接口流体连接。
背景技术
蒸汽轮机用于产生电能。在正常运行中,在蒸汽发生器中产生蒸汽并且将蒸汽朝向蒸汽轮机引至流入区域。在蒸汽轮机中,蒸汽的热能转换为转子的机械旋转能。然而,由蒸汽轮机输送更多功率的运行状态是可能的,这通过如下方式实现,即在蒸汽发生器中使用附加点燃装置,所述附加点燃装置造成蒸汽质量流提高。蒸汽质量流的这种提高以已知方式经由在叶片系统区域中位于下游的过载流入区域输送到蒸汽轮机中。为此,从新鲜蒸汽管路实现分支,所述分支在下游与过载流入区域流体连接。
在所述过载管路中设置有过载阀,所述过载阀在正常情况下关闭。在新鲜蒸汽管路中设置有快速关闭阀和调节阀。过载阀在一些实施方式中设置在蒸汽轮机下方,这造成不必要的附加的管道连接。附加地,过载阀和管道必须被固持,这意味着附加的耗费。过载阀定位在涡轮机中心下方,由此过载阀的排水装置变为绝对低点进而使得排水站是强制性必需的。
发明内容
本发明的目的是,提出一种成本更低的装置和一种用于过载运行的方法。
这通过根据权利要求1的装置和根据权利要求4的方法实现。
有利的改进方案在从属权利要求中给出。
本发明以如下观点为出发点,能够避免第二阀的复杂的管路铺设,所述第二阀能够称作为过载阀。同样能够弃用附加的排水站。相对而言,第一阀和第二阀以彼此间小的间距设置在蒸汽轮机上。
在本发明的第一方面中,蒸汽轮机还具有过载流入区域,所述过载流入区域与第二阀流体连接。
在本发明的第二方面中,蒸汽轮机具有针对流动方向设计的叶片系统区域,其中过载流入区域在沿流动方向位于下游的叶片级之后通入到叶片系统区域中。
在本发明的另一方面中,连接口在内壳体上相对置地构成。
本发明的上文所描述的特性、特征和优点以及实现这些的方式和方法结合实施例的下述描述变得更清楚且更易理解,结合附图详细阐述所述实施例。
附图说明
下面,根据附图描述本发明的实施例。所述附图没有符合比例地示出实施例,更确切地说用于阐述的附图以示意性的和/或略微失真的方式示出。在图中对直接可见的原理的补充方面参照相关的现有技术。
图1示出根据现有技术的具有蒸汽轮机和过载流入区域的装置。
图2示出具有过载装置的根据本发明的装置。
图3示出以双流式的实施方案的根据本发明的装置。
图4示出示意的侧视图。
具体实施方式
图1示出根据现有技术的装置1。装置1包括具有双壳式的壳体(未示出)的蒸汽轮机2,所述壳体包括外壳体3和设置在所述外壳体中的内壳体(未示出)。此外,蒸汽轮机2包括引导穿过外壳体3的连接部4。蒸汽轮机2包括可转动地安装的转子和用于新鲜蒸汽的流入区域5。流入区域5与新鲜蒸汽管路9流体连接。在所述新鲜蒸汽管路9中设置有快速关闭阀7和调节阀8。此外所述装置1包括分支9,在所述分支9处设置有过载管路10,并且所述过载管路通入到蒸汽轮机2中的过载流入区域11中。在过载管路10中设置有过载阀12,所述过载阀在实际构造中设置在蒸汽轮机2下方,这造成缺陷。
在正常运行中,新鲜蒸汽经由新鲜蒸汽管路6和快速关闭阀7和调节阀8流入到蒸汽轮机的流入区域5中。蒸汽的热能转换为转子的机械能。最后,转子的旋转能够借助于发电机转换为电能。在过载运行中,也就是说,蒸汽发生器产生比在正常运行中更多的蒸汽流,过载阀12被打开,并且一部分的蒸汽经由过载管路流入到过载流入区域11中。在正常运行中,关闭过载阀12。通过打开过载阀12能够提高蒸汽轮机2的功率。
图2示出根据本发明的装置1。新鲜蒸汽管路6经由快速关闭阀7和调节阀8与流入区域5流体连接。连接部4构成有一对连接口4a、4b,所述连接口由第一连接口4a和第二连接口4b形成,所述第一连接口和第二连接口在内壳体上构成。装置1还包括第二阀12,所述第二阀能够称作为过载阀并且构成为用于导出蒸汽。这经由导出管路13实现并且通入到过载管路10中通入到过载流入区域11中。因此,在所述根据本发明的装置1中,在过载情况下流入的蒸汽经由新鲜蒸汽管路6引导到快速关闭阀7中,并且随后引导到调节阀8中,并且经由流入区域5部分地流入到流动通道中,并且部分地再经由导出管路13在蒸汽轮机2上流出。从蒸汽轮机2中流出的蒸汽经由过载阀12和过载管路10流入到过载区域11中。
图3示出根据图2的装置的一个改进的实施方式。在根据图3的装置中,同样将过载蒸汽经由过载管路10引入到过载流入区域11中。根据图3的装置与根据图2的实施方案的不同是,蒸汽轮机2构成为具有第一流道14和第二流道15的双流式蒸汽轮机。新鲜蒸汽经由新鲜蒸汽管路6流入到第一流道14中并且从那里从蒸汽轮机2中流向中间过热器(未示出)。接着,蒸汽经由中压蒸汽管路16和中压快速关闭阀17和中压调节阀18流入到中压流入区域19中。接着,蒸汽在第二流道15中穿过流动通道从蒸汽轮机2中流出。蒸汽的热能在此转换为转子的机械能。
图4示出流入的示意侧视图。基本上,蒸汽轮机2关于垂直的对称轴线31对称地构成,所述对称轴线穿过旋转轴线30。在图4中没有示出的转子以可围绕旋转轴线转动的方式旋转对称地支承。第二连接口4b和导出管路13关于对称轴线31镜像对称地与连接口4a相对置地设置。第二连接口4b能够如何相对置设置的第二变型方案在图4中由虚线32示出。在此,第二连接口4b相对置地设置在假想的线33上,所述假想的线穿过连接口4a和旋转轴线30。第二连接口4b在此也位于假想的线33上。
尽管通过优选的实施例详细阐述和描述本发明的细节,但是本发明不局限于公开的实例并且从中能够由本领域技术人员推导出其他变型方案,而不脱离本发明的保护范围。
