技术领域
本公开内容涉及一种用于检测燃气轮机燃料供应系统的燃料回路中的泄漏的方法。
背景技术
燃气轮机大体上包括成串流顺序的压缩机区段、燃烧区段和涡轮区段。在操作期间,空气经由入口系统进入压缩机,且在其朝压缩机排放口或扩散器壳发送时逐渐地压缩。压缩的空气发送到燃烧区段的独立燃烧器中。压缩的空气的至少一部分与燃料混合且在限定于各个燃烧器内的对应燃烧室内焚烧,由此生成高温和高压燃烧气体。
液体燃料可从燃料供应滑道或系统经由各种管、导管、阀和管配件供应至燃烧器。在安装期间和/或一定时间内,燃料泄漏可在配件周围存在或发生。用于检测燃料泄漏的一个已知方法在于使具有燃料或惰性气体(诸如氮)的燃料回路在完全工作压力下加压,完全工作压力通常从大约500psig起或更大。尽管有效,但该泄漏检测过程具有一些缺陷。例如,一个缺陷在于当前的过程是耗时的。更具体而言,为了完成该检测过程,发送至各个燃烧器或燃烧筒的管必须在对应的止回阀或3通阀上游断开,且在再连接之前单独地测试。其主要原因在于止回阀或3通阀构造成在大约100psig下打开。结果,如果管是连接的,则燃料回路将在压力超过100psig时减压,由此引起测试压力的损失。这还可意味着止回阀或3通阀处的最终连接不可在测试中验证。此外,500psig和更高的测试(尤其是利用可压缩的流体的)可需要针对技术人员的特殊安全性考虑。
因此,所需的是提供用于检测燃气轮机的燃料回路中的泄漏的改善的方法或过程。更具体而言,需要提供用于检测用于燃气轮机燃烧器的燃料系统配件或流体联接泄漏而能够使对应的管或导管留在原地的方法。

包括对本领域的技术人员的其最佳模式的本发明的完整且开放的公开内容在包括参照附图的说明书的其余部分中更详细阐释,在附图中:
图1为本发明的范围内的示例性基于燃气轮机的发电设备的功能框图;
图2为可并入本发明的至少一个实施例中的示例性燃料供应系统的简化截面侧视图;以及
图3提供了根据本公开内容的一个实施例的用于检测燃料供应系统的管配件和/或其它流体联接件或连接处的燃料泄漏的方法的流程图。
具体实施方式
现在将详细参照本发明的实施例,其一个或更多个实例在附图中示出。该详细描述使用了数字和字母标号来表示附图中的特征。附图中相似或类似的标记用于表示本发明的相似或类似的部分。如本文中所使用的,用语"第一"、"第二"和"第三"可互换使用,以将一个构件与另一个区分开,且不旨在表示独立构件的位置或重要性。用语"上游"和"下游"是指相对于流体通路中的流体流的相对方向。例如,"上游"是指流体流自的方向,且"下游"指示流体流至的方向。用语"径向地"是指基本垂直于特定构件的轴向中心线的相对方向,且用语"轴向地"是指基本平行于和/或同轴地对准特定构件的轴向中心线的相对方向。
本文中所使用的用语用于仅描述特定实施例的目地,且不旨在限制本发明。如本文中所使用的,单数形式"一个"、"一种"和"该"旨在也包括复数形式,除非下文清楚地另外指出。还将理解的是,用语"包括"和/或"包含"在用于此说明书中时表示指出的特征、整数、步骤、操作、元件和/或构件的存在,但并未排除存在或添加一个或更多个其它特征、整数、步骤、操作、元件、构件和/或其组合。
各个实例通过阐释本发明的方式提供,而不限制本发明。实际上,本领域的技术人员将清楚的是,可在本发明中制作出改型和变型,而不会脱离其范围或精神。例如,示为或描述为一个实施例的一部分的特征可用于另一个实施例上以产生又一个实施例。因此,期望本发明覆盖归入所附权利要求和其等同物的范围内的此类改型和变型。
本发明的实施例采用用于检测燃气轮机的燃料供应回路的燃料配件泄漏的方法的形式。该方法包括使用空气或惰性加压气体(诸如氮)将待测试的燃料回路加压至大约50psig到大约80psig。该方法然后包括使用超声装置来检测各种管配件和/或流体联接件或连接处的泄漏。在此压力下检测的泄漏可在500psig的液体燃料的完全工作压力下等于大约60滴每分钟。泄漏检测方法解决了当前已知的泄漏检测过程可发生的两个问题。首先,不需要沿燃料回路断开任何连接,因为测试压力保持低于特定燃烧器的大约100psig的止回阀破裂压力。第二,大约50psig到大约80psig的范围中的燃料回路压力可减小与在大约psig的完全操作压力下测试相关联的潜在风险。
超声装置大体上设计成检测由配件处的泄漏产生的湍流生成的超声噪音。该方法成功的一个原因在于超声是定向的,且因此可由超声装置检测到,因此允许了操作者快速找到噪音源。利用已知过程,每个独立配件连接(且存在几百个连接)必须以泄漏检测液体(诸如"Snoop")喷淋,且然后目视检测气泡。利用本文提供的方法,超声检测装置可立即找到大的泄漏,且仅具有非常小泄漏的可疑配件可能需要以液体泄漏放大物跟进。此外,如本文提供的方法不需要Snoop施加来很努力地达到连接处,诸如泄漏180与Snoop操作者成180度分离的连接。
现在参看附图,其中相同的数字表示附图各处相同元件,图1提供了可结合本发明的各种实施例的包括燃气轮机10的示例性发电设备地点的功能框图。如图所示,燃气轮机10可大体上包括入口区段12。入口区段12可包括一系列过滤器、冷却盘管、水气分离器和/或用于净化和以其它方式调节空气14或进入燃气轮机10的其它工作流体的其它装置。空气14流至压缩机区段,在该处,压缩机16将动能逐渐给予空气14来产生压缩的空气18。
压缩的空气18与来自燃料供应系统22的燃料20(诸如液体)相混合,以在一个或更多个燃烧器24内形成可燃混合物。可燃混合物焚烧来产生具有高温、高压和高速的燃烧气体26。燃烧气体26流过涡轮区段的涡轮28来产生功。例如,涡轮28可连接到轴30上,以便涡轮28的旋转驱动压缩机16来产生压缩的空气18。作为备选或此外,轴30可将涡轮28连接到发电机32上来用于产生电力。来自涡轮28的排出气体34流过排气区段36,其将涡轮28连接到涡轮28下游的排气器38上。排气区段36可包括例如余热回收蒸汽发生器(未示出),以用于在排出气体34释放到环境之前清洁和获取来自排出气体34的附加热。
图2提供了可并入图1中所示的燃气轮机10中的示例性燃料供应系统22的简化示意图。如图2中所示,燃料供应系统22大体上包括至少流动控制或停止阀40或其它促动类型的阀,其与液体燃料源42流体连通。至少一个压力传感器44(诸如压力变送器或量规)设置在流动控制阀40下游和燃料分配歧管或分流器46上游。通风口或入口端口48定位在压力传感器44与燃料分配歧管46之间。在一个实施例中,入口端口48可设置在燃料分配歧管46下游。在特定实施例中,入口端口48联接到压缩介质供应源50上。在特定实施例中,压缩介质供应源50可包括空气供应源(诸如仪器空气供应源)。在其它实施例中,压缩介质供应源可包括加压流体源。
在各种实施例中,燃料分配歧管46包括与流动控制阀40和/或液体燃料源42流体连通的入口52,以及设置在入口52下游的多个出口54。各个出口54给送对应的燃料回路56。各个燃料回路56将燃料分配歧管46流体地联接到对应的燃烧器24上。尽管六个出口54、六个燃料回路56和六个燃烧器24仅出于图示目的示出,但应当理解的是,燃料分配歧管46可包括取决于特定燃气轮机框架的燃烧器24的数目的任何数目的出口,且本公开内容不限于六个出口54、六个燃料回路56或六个燃烧器24,除非权利要求中另外提供。
各个燃料回路56均包括对应的止回阀58,其提供对应出口54与对应燃烧器24之间的流体连通。在特定实施例中,止回阀58构造成在小于大约100psig的燃料回路54内的压力下保持闭合,由此防止燃料流至对应的燃烧器24。(多个)止回阀58构造成在超过大约100psig的压力下打开,因此允许燃料流至对应的燃烧器24。在特定实施例中,止回阀58可为二通阀、三通阀、四通阀或可为基于流体回路内的压力控制流动的任何类型的阀。
液体燃料供应源42、流动控制阀42、(多个)压力传感器44、(多个)入口端口48、燃料分配歧管46、止回阀58和燃烧器24中的每一个均经由各种流体导管、管道、管和管配件流体地联接。在各种实施例中,多个管配件60设置在各个止回阀58上游和流动控制阀40下游。在特定实施例中,至少一个管配件62可设置在流动控制阀40下游和燃料分配歧管46上游。
在燃气轮机10的点火操作期间,燃料20从液体燃料供应源42流过流动控制阀40且流入燃料分配歧管46。燃料20然后经由多个出口54发送到各种对应的燃料回路56。一旦特定燃料回路56内的压力超过预定阈值压力(诸如100psig),则对应止回阀58自动地打开,因此允许燃料20流入对应的燃烧器24。(多个)压力传感器44提供表示当止回阀58打开(诸如当压力超过预定压力阈值时)时的流动控制阀40与燃烧器24之间的燃料供应系统22内的燃料压力的压力读数。(多个)压力传感器44提供表示当(多个)止回阀58闭合(诸如当压力低于预定阈值压力时)时的流动控制阀40与(多个)止回阀58之间的燃料供应系统22内的燃料压力的压力读数。
在安装期间和/或一定时间内,燃料泄漏可在定位于流动控制阀40与止回阀58之间的各种管配件60处形成。因此,本文中提供了用于检测管配件60和/或其它流体联接件或连接处的泄漏的方法100。图3提供了根据本发明的一个实施例的方法100的流程图。
在步骤102处,方法100包括关闭经由流动控制阀40至燃料供应系统22的燃料流。通过闭合流动控制阀40,来自液体燃料供应源42的燃料流关闭。在闭合流动控制阀40之前或之后,燃料供应系统22可经由吹扫介质(诸如空气)吹扫来清除任何残余液体燃料(特别是在流动控制阀40下游)。
在步骤104处,方法100包括经由压缩介质供应源50用压缩介质64(诸如空气)加压燃料供应系统22。燃料供应系统22应当在小于止回阀58的预定阈值压力的目标压力下加压,使得止回阀不会破裂或打开。结果,压力传感器44将提供表示流动控制阀40与止回阀58之间的压力的压力读数。在一个实施例中,阈值压力在大约100psig到大约130psig的范围内。在一个实施例中,阈值压力为100psig。在一个实施例中,目标压力在大约40psig到大约90psig的范围内。在一个实施例中,目标压力为50psig。在一个实施例中,目标压力为80psig。
一旦流动控制阀40与止回阀58之间的压力达到其目标压力,则压缩介质供应源58应当关闭,且燃料供应系统22内的压力应当被监测,以检测除通风端口48下游的管配件泄漏之外的任何泄漏。例如,压力传感器44处的压力读数的降低可指出有故障的止回阀58、有故障的流体联接件或燃料供应系统22内的其它泄漏。如果在此点检测到泄漏,则燃料供应系统22可减压且解决泄漏。燃料供应系统22然后可再加压且监测来确保已经解决泄漏。如果压力继续下降,则之前的步骤可重复,直到燃料供应系统内的压力读数稳定。如本文中所使用的"稳定"可表示系统中的压力不会每分钟改变大于大约10psig的状态。
在步骤106处,方法100包括使用超声检测装置66(诸如由UE Systems Inc.(Elmsford, New York, U.S.A)提供的Ultraprobe® 9000)来跟踪和/或检测沿燃料供应系统的各种管和/或流体联接件和/或沿燃料分配歧管46与对应止回阀58之间的燃料回路56中的一个或更多个的泄漏。当操作者接近各个管配件60或流体连接/联接件时,超声装置应当运行,由此允许操作者能够听到沿管路行进的泄漏,且确定管路/配件60中的泄漏的存在。此外,操作者将能够限定环境噪音基准,以及从基准的声音的可辨别的阶梯变化将在遇到关于环境背景噪音的配件泄漏或其它泄漏时发生。在其它实施例中,存在屏蔽/隔离技术,其可用于减少竞争的超声噪音,因此有助于提高检测能力和隔离泄漏的位置。
在各个管配件60处,操作者可试图转动管配件60的相关连接螺母(未示出),以确保其不会用手拧紧。在连接处,操作者可使超声检测装置66的接收器部分68瞄准或指向管配件60,且听连接螺母上游和下游两者的管配件60的整个圆周周围。如果连接是接管的或T形的,则这将分别针对所有两个或三个连接来完成。在特定实施例中,操作者可将空气泄漏检测液体或"液体泄漏放大物"(诸如快速汽化液体(即,酒精))喷淋在管配件60中的一个或更多个上。由超声装置检测到的液体起泡和/或'冒泡'声音将指出泄漏。如果你使用LLA或一些增强材料,则可检测的db水平未必增大。结果,可使用以气泡冒出检测的第二模式。在一个实施例中,液体泄漏放大物此外或作为备选用于施加泄漏检测液体。液体泄漏放大物为特别设计成具有高表面张力的流体,使得其在气泡爆开时产生不同的"破裂"声音。生成的气泡非常小,不同于由通常称为"Snoop"的肥皂/水混合物生成的气泡。
应当注意的是,在一些备选实施方式中,步骤中提出的功能可不同于附图中提出或本文所述的顺序发生。例如,取决于涉及的功能,相继示出的两个步骤实际上可基本同时执行,或步骤有时可以以相反顺序执行。尽管本文示出和描述了特定实施例,但应当认识到的是,计算为实现相同目的的任何布置都可置换所示的特定实施例,且本发明在其它环境中具有其它应用。本申请旨在覆盖本发明的任何改变或变型。所附权利要求绝不旨在将本发明的范围限于本文所述的特定实施例。
