Description

天然气燃烧器的燃烧监控方法、装置和系统 技术领域
本发明涉及燃烧器领域，尤其涉及一种天然气燃烧器的燃烧监控方法、装置和系统。
背景技术
随着天然气中的氢含量的逐渐增多，天然气变得越来越危险。与纯净的甲烷相比，氢气的可燃范围更高，当容积从4％到75％时均可燃，而甲烷是5％到15％，点火能量比甲烷小15倍，燃烧速度比甲烷高8倍，因此，其比甲烷更易爆炸。
对于在高氢气含量状态下，天然气燃烧器的燃烧所潜在的主要风险是：
-由于氢气高反应性而产生的逆燃(flash back)所造成的燃烧器过热；
-由于氢气更快速运动而产生的较天然气燃烧不一样的化学变化所导致的燃烧不稳定性；
-由于氢气更高的绝热燃烧温度所导致的氮氧化物排放的增加。
在现有技术中，通常通过在燃烧器的火焰出口处安装热电偶来进行温度监测，并基于所监测到的温度信号触发不同的保护操作。这种方法仅能控制天然气燃烧中的过热风险，无法避免燃烧的不稳定性以及氮氧化物排放的增加。

在阅读下述说明之后，本领域技术人员将清楚地认识到，本发明的教导可容易地用于燃烧监测和控制系统中。本发明所述的方法、系统与装置，对于预混燃烧器或扩散式燃烧器均可适用。优选地，本发明可应用于燃气涡轮机(Gas Turbine)中。
图1表示本发明一个实施例的一种应用天然气燃烧控制系统的天然气燃烧系统架构图。所述天然气燃烧控制系统包括燃烧控制器10与气体分析仪20。图1所显示的系统架构仅是应用天然气燃烧控制系统的一种示例。
燃烧控制器10通过有线连接或无线连接的方式，与气体分析仪20和位于进气管道30中的控制阀50相连接，以获取气体分析仪20所发送的信号并向所述进气管道30中的控制阀50发送或获取信息。
气体分析仪20与天然气燃烧器40的进气管道30相连接，该连接能够使得气体分析仪20从进气管道30中取样，即获取天然气燃烧器40所燃烧的天然气样本。
气体分析仪20对所取样的天然气进行分析，以获取对该天然气中所包含的各类气体成分与对应的含量的测量结果。在此，所述分析方法包含两种方式：第一，基于预先设定的气体成分，分析在该天然气中所包含的该气体的含量，例如，优选地，预先设定分析该天然气氢气的含量，则气体分析仪20对该天然气中的氢气含量进行分析与测定，如氢气含量为15％；第二，气体分析仪20首先分析该天然气中所包含的各种气体的成分类别，如甲烷、乙烷、二氧化碳、氮气、氢气、硫化氢等，然后基于所分析的气体成分，分别测定各类气体成分所对应的气体含量。
然后，气体分析仪20将该测量结果发送至燃烧控制器10。
燃烧控制器10获取到该测量结果后，将该测量结果作为输入数据，输入到预置的控制模型中，并根据所述控制模型对该输入数据的输出结果，来直接或间接地确定该测量结果所对应的控制信息。其中，该控制模型与所述天然气中的气体成分与对应的含量相关。例如，该控制模型中可直接包含了不同的天然气气体成分与含量所对应的不同控制信息；或者，该控制模型中包含了不同天然气气体成分与含量所对应的不同进气流量等，然后，燃烧控制器10根据该进气流量来确定相对应的控制信息，如是加大流量或减小流量等。
本领域技术人员应能理解，其中，所述控制模型可以是以二维或多维曲线的方式呈现的，如横坐标轴为氢气的含量值，纵坐标轴为天然气流量值等；也可以是表格或其他呈现方式。
其中，所述控制模型的确定可包含两种方式：第一，基于人工设置；第二，在默认设置的基础上，基于反馈信号来进行实时调整。在此，所述反馈信号可以是下文所述的各类传感器信号。

优选地，燃烧控制器10还可以根据所述测量结果，确定当前所对应的风险等级，例如，高风险等级、中风险等级、低风险等级。以测量氢气含量为例：
若氢气含量超过正常限度并达到低风险等级，则发送报警信息；
若氢气含量超过正常限度并达到中风险等级，则触发天然气燃烧器40关闭；
若氢气含量超过正常限度并达到高风险等级，则触发天然气燃烧器40跳闸。
优选地，燃烧控制器10还可以结合其他信号来确定当前对应的风险等级并触发相对应的操作。例如，若氢气含量超过正常限度并达到高风险等级，同时天然气燃烧器40的轰鸣在某一持续时间内超过某一水平，则触发天然气燃烧器40跳闸。所述轰鸣可通过在天然气燃烧器40上放置轰鸣传感器来 获取。

气体分析仪20对所取样的天然气进行分析，以获取对该天然气中所包含的各类气体成分与对应的含量的测量结果。在此，所述分析方法包含两种方式：第一，基于预先设定的气体成分，分析在该天然气中所包含的该气体的含量，例如，优选地，预先设定分析该天然气氢气的含量，则气体分析仪20对该天然气中的氢气含量进行分析与测定，如氢气含量为15％；第二，气体分析仪20首先分析该天然气中所包含的各种气体的成分类别，如甲烷、乙烷、二氧化碳、氮气、氢气、硫化氢等，然后基于所分析的气体成分，分别测定各类气体成分所对应的气体含量。
然后，气体分析仪20将该测量结果发送至燃烧控制器10。

然后，燃烧控制器10将该测量结果以及该反馈信号作为输入数据，输入到预置的控制模型中，并根据所述控制模型对该输入数据的输出结果，来直接或间接地确定该测量结果与该反馈信号所对应的控制信息。其中，所述控制模型与所述天然气中的气体成分与对应的含量以及所述反馈信号相关。
例如，该控制模型中可直接包含了不同的天然气气体成分与含量下，不同的反馈信号所对应的不同控制信息；或者，该控制模型中包含了不同天然气气体成分与含量以及不同的反馈信号所对应的不同进气流量等，然后，燃烧控制器10根据该进气流量来确定相对应的控制信息，如是加大流量或减小流量等。

以图10为例，图10示出了根据本发明的一个实施例的一种包含两个传感器的天然气燃烧器的示意图。天然气燃烧器40上布置有两个温度传感器701、702，共同检测该天然气燃烧器的温度。若其中一个温度传感器，如温度传感器701失效，则燃烧控制器10不再从该温度传感器701处获取温度信号，因此判定该温度传感器701失效，并发出报警信息。
优选地，当所述燃烧控制器10还获取所述反馈信号时，所述燃烧控制器10可以根据所述测量结果中的气体成分与对应的含量，结合所述反馈信号，确定当前对应的风险等级。例如，若氢气含量超过正常限度，同时排放传感器90的排放信号显示排放含量超标，则可确定当前对应的风险等级为中风险等级；若氢气含量超过正常限度，同时排放传感器90的排放信号显示排放含量超标且温度传感器701或702的温度信号显示高温度，则可确定当前对应的风险等级为高风险等级；或者若氢气含量超过正常限度的值很高，同时温度传感器701或702的温度信号显示高温度，则可确定当前对应的风险等级为高风险等级。
在此，本领域技术人员应能理解上述说明仅为举例，并非对本发明的限制，其他结合以确定风险等级的方式同样适用于本发明，并包含在本发明的保护范围内。

在步骤S101中，燃烧控制器10获取对所述天然气燃烧器的进气管道中 的天然气的测量结果，其中，所述测量结果中包括所述天然气中的气体成分与对应的含量。
其中，燃烧控制器10可以与如气体分析仪等设备相交互，以获取气体分析仪所发送的测量结果，此外，燃烧控制器10还可以与其他能够提供所述测量结果的设备相交互，以获取所述测量结果。
在步骤S101中，燃烧控制器10取到该测量结果后，执行步骤S102。在步骤S102中，燃烧控制器10将该测量结果作为输入数据，输入到预置的控制模型中，并根据所述控制模型对该输入数据的输出结果，来直接或间接地确定该测量结果所对应的控制信息。其中，该控制模型与所述天然气中的气体成分与对应的含量相关。例如，该控制模型中可直接包含了不同的天然气气体成分与含量所对应的不同控制信息；或者，该控制模型中包含了不同天然气气体成分与含量所对应的不同进气流量等，然后，燃烧控制器10根据该进气流量来确定相对应的控制信息，如是加大流量或减小流量等。
本领域技术人员应能理解，其中，所述控制模型可以是以二维或多维曲线的方式呈现的，如横坐标轴为氢气的含量值，纵坐标轴为天然气流量值等；也可以是表格或其他呈现方式。
其中，所述控制模型的确定可包含两种方式：第一，基于人工设置；第二，在默认设置的基础上，基于反馈信号来进行实时调整。
然后执行步骤S103，在步骤S103中，燃烧控制器10根据所述控制信息，通过调整例如位于天然气燃烧器的进气管道上的控制阀等方式，来对所述天然气燃烧器的进气管道中的天然气流量进行调整。在此，本领域技术人员应能理解，除了调整控制阀外，其他的调整方式如能适用于本发明，同样包含在本发明的保护范围内并以引用的方式包含于此。
图8是根据本发明的另一个实施例的一种燃烧控制器控制方法的流程图。
其中，步骤S101与步骤S103与图7所示对应步骤相同或相似，故在此不再赘述，并通过引用的方式包含于此。
在步骤S104中，燃烧控制器10通过与所述天然气燃烧器所对应的传感器或其他能够提供相应信号的设备相交互，以获取所述天然气燃烧器的动态传感器的动态信号、排放传感器的排放信号、温度传感器的温度信号中至少 任意一个信号，以作为反馈信号。
然后，步骤S102获取步骤S101所发送的所述测量结果，以及获取步骤S104所发送的反馈信号，将该测量结果以及该反馈信号作为输入数据，输入到预置的控制模型中，并根据所述控制模型对该输入数据的输出结果，来直接或间接地确定该测量结果与该反馈信号所对应的控制信息。其中，所述控制模型与所述天然气中的气体成分与对应的含量以及所述反馈信号相关。
例如，该控制模型中可直接包含了不同的天然气气体成分与含量下，不同的反馈信号所对应的不同控制信息；或者，该控制模型中包含了不同天然气气体成分与含量以及不同的反馈信号所对应的不同进气流量等，然后，在步骤S102中，燃烧控制器10根据该进气流量来确定相对应的控制信息，如是加大流量或减小流量等。
本领域技术人员应能理解，其中，所述控制模型可以是以多维曲线的方式呈现的，如一个横坐标轴为氢气的含量值，另一个或多个横坐标轴分别为一种反馈信号的值，纵坐标轴为天然气流量值等；也可以是表格或其他呈现方式。
其中，所述控制模型的确定可包含两种方式：第一，基于人工设置；第二，在默认设置的基础上，基于所述反馈信号来进行实时调整。
优选地，所述控制模型的控制逻辑还与所述传感器的布置位置相关。其中，所述控制逻辑即为基于一定的输入(即上述反馈信号的类型与对应值)以确定对应输出(即所对应的控制信息)的逻辑。而当所述传感器的布置位置不同的情况下，同样的反馈信号所对应的控制信息不同。
例如，若某一温度传感器在天然气燃烧器上的位置比另一温度传感器在天然气燃烧器的位置更接近火焰，则对前者的控制模型不同于对后者的控制模型，如前者的报警温度会高于后者的报警温度等。
优选地，该方法还包括触发报警信息的步骤(未示出)，具体地，在该步骤中，若在所述燃烧控制器10所对应的天然气燃烧器上所布置的每类传感器包括一个或多个，则若所布置的每类传感器中的至少任意一个失效，则所述燃烧控制器10触发报警信息。
以图10为例，图10示出了根据本发明的一个实施例的一种包含两个传感器的天然气燃烧器的示意图。天然气燃烧器40上布置有两个温度传感器701、702，共同检测该天然气燃烧器的温度。若其中一个温度传感器，如温 度传感器701失效，则燃烧控制器10不再从该温度传感器701处获取温度信号，因此判定该温度传感器701失效，并由报警单元发出报警信息。
图9是根据本发明的另一个实施例的一种燃烧控制器控制方法的流程图。
其中，步骤S101、步骤S102、步骤S103、步骤S104与图7或图8所示对应步骤相同或相似，故在此不再赘述，并通过引用的方式包含于此。
在步骤S105中，燃烧控制器10能够从步骤S101处获取所述测量结果，并根据所述测量结果，确定当前所对应的风险等级，例如，高风险等级、中风险等级、低风险等级。
在步骤S106中，燃烧控制器10基于所述风险等级，触发与所述风险等级相对应的操作。
以测量氢气含量为例：
若氢气含量超过正常限度并达到低风险等级，则发送报警信息；
若氢气含量超过正常限度并达到中风险等级，则触发天然气燃烧器关闭；
若氢气含量超过正常限度并达到高风险等级，则触发天然气燃烧器跳闸。
优选地，在步骤S105中，燃烧控制器10还可以结合其他信号来确定当前对应的风险等级并触发相对应的操作。例如，若氢气含量超过正常限度并达到高风险等级，同时天然气燃烧器的轰鸣在某一持续时间内超过某一水平，则触发天然气燃烧器跳闸。所述轰鸣可通过在天然气燃烧器上放置轰鸣传感器来获取。
优选地，当步骤S105还能够从步骤S104处获取所述反馈信号时(图中未示出)，在步骤S105中，燃烧控制器10可以根据所述测量结果中的气体成分与对应的含量，结合所述反馈信号，确定当前对应的风险等级。例如，若氢气含量超过正常限度，同时排放传感器的排放信号显示排放含量超标，则可确定当前对应的风险等级为中风险等级；若氢气含量超过正常限度，同时排放传感器的排放信号显示排放含量超标且温度传感器的温度信号显示高温度，则可确定当前对应的风险等级为高风险等级；或者若氢气含量超过正常限度的值很高，同时温度传感器的温度信号显示高温度，则可确定当前 对应的风险等级为高风险等级。
在此，本领域技术人员应能理解上述说明仅为举例，并非对本发明的限制，其他结合以确定风险等级的方式同样适用于本发明，并包含在本发明的保护范围内。
本领域技术人员应当理解，上面所公开的各个实施例，可以在不偏离发明实质的情况下做出各种变形和改变。因此，本发明的保护范围应当由所附的权利要求书来限定。
