有用的指南的最佳燃烧分析仪测试Kit

回到当天,锅炉调整是相对简单的事情。您根据需要调整或向下调整气体,然后通过近似进行操作。火焰过于柔软和橙色吗?稍微调低气体。火焰小而尖锐吗?把它抬起一个smidge。如果火焰是蓝色和圆形的,那么一切都很好。就最大化锅炉或炉子的效率而言,这是有史以来最多的人。

但是时间继续前进,还有一些更新,更好的方法来提高效率。通过使用一组电子传感器,您可以确定要离开燃烧室的氧气和二氧化碳。然后,您可以考虑到这些科学测量的燃料。这比盯着火焰要好得多,直到看起来“足够好”。读取燃烧室输出的这种过程称为燃烧分析。这对燃油效率也不重要。这对于安全也很重要。许多制造商的保修甚至会特别需要定期测试,以便您维护承保范围。

A modern combustion analyzer is compact, and is designed for handheld use like a万用表。这使它们成为任何技术人员或检查员工具包的重要组成部分。现在,我们将审查钱可以购买的三个最佳燃烧分析仪测试套件。首先,我们将检查Testo310。这是一个完整的测试套件,并具有内置的,易于发空的冷凝水陷阱。接下来,我们将检查Bacharach Fyrite Intech。

It comes with internal storage for 10 separate records, along with a printer for recording that information. Last but not least, we’ll look at the Fieldpiece SOX3. This is a more affordable test kit, with a field-replaceable O2 sensor. Which one is the best of the bunch? Let’s dig a little deeper, and find out!

How Does Combustion Analysis Work?

燃烧分析之所以起作用,是因为燃烧是一种可预测的化学过程。毕竟,从根本上讲,燃烧只是一种化学反应。化石燃料由碳氢化合物或碳和氢的链组成。当这种材料燃烧时,它会与空气中的氧气反应。碳氢化合物和氧气变成二氧化碳(CO2)和水(H20)。在一个完美的世界中,您可以利用对这种化学反应的理解来计算理想的燃油空气平衡。

Methane is a good example, and it also just happens to be the main component of natural gas. A methane molecule has the chemical name CH4. This means it consists of one carbon atom and four hydrogen atoms. Meanwhile, oxygen in the air consists of O2 molecules, or bonded pairs of individual oxygen atoms. This makes it easy to balance the chemical equation. We can combine two oxygen molecules with one methane molecule to get one molecule of CO2 and two of H20. We also produce heat in the process, which is why we’re going through all this trouble to begin with!

因此,如果我们将每个甲烷分子的两个分子放入两个分子,则全甲烷发动机将是最有效的。轻松,对吧?不太快。获得这种性能将需要100%的效率。在现实生活中,从来没有100%的效率。有一些随机变量总是会抛弃。例如,燃料和空气需要时间在燃烧室内混合。如果分子永远不会接触,他们将无法做出反应!同样,必须有足够的热量,并且在腔室中必须有足够的时间才能发生燃烧。

实际上,这可能导致许多副产品。如果混合物中的氧气不足,则可以最终得到一氧化碳(CO)或烟灰(C)。前者对您的健康有害,而后者对环境有害并构成火灾危害。过多的氧气也可以通过用浪费的氧气淹没燃烧室来降低效率。

We can determine this by measuring the amount of oxygen, CO2, and CO in exhaust. Ideally, there should be near-zero CO, the maximum amount of CO2, and a little oxygen. A combustion analyzer can detect all of these molecules, and tell you their ratio in the exhaust. Some combustion analyzers can also detect other compounds. For example, many can detect nitrogen oxides from excessive heat, or sulfur dioxide from dirty fuel.

To do this, you simply insert a probe into the flu and sample some of the exhaust gas. During this time, a temperature measurement is also taken, as is a draft measurement. This is a measurement of the difference in air pressure between the inside and outside of the flu. All of these measurements are then put into the analyzer’s on-board computer, which performs a little wizardry. You’ll then get a readout with a variety of information that can be used to fine-tune the combustion.

这些读数是什么意思?

那么,您如何解释这些读物?让我们从三个最重要的测量值开始:O2,CO2和CO。正如我们已经确定的那样,理想的排气性应仅包含水蒸气和CO2。它还应包含空气中留下的氮。正如我们已经建立的那样,燃料与空气的理想之比。为了实现充分的燃烧,您还需要一定数量的额外空气。这种空气称为“过量空气”,通常约占理想空气的15%。确切的比例将在一定程度上取决于锅炉或炉的设计。

As a general rule, there should be no detectable CO in the exhaust. If there is, there’s not enough excess air flowing into the combustion chamber. As you increase the ratio of oxygen to fuel, you’ll notice a steep drop-off in the quantity of CO. This will be accompanied by a proportional rise in CO2 concentration. After CO has disappeared, the amount of CO2 will continue to increase to a certain point. If more oxygen is added beyond that point, the amount of CO2 will decrease. If you want maximum efficiency, you want to be producing the maximum amount of CO2. The exact maximum will depend on the type of fuel you’re burning.

某些燃烧分析仪也可以感知常见污染物。其中最常见的是氮氧化物,NO和NO2。这些气体有助于烟雾,酸雨和地面臭氧。它们总是少量存在,但高浓度表明燃烧室太热了。一些分析仪测试试剂盒也可以检测二氧化硫(SO2)。SO2具有与NO和NO2相同的有害效果。但是,使用低硫或去硫化燃料可以轻松消除它。

Testo 310

Testo 310

Testo 310是一种中型燃烧分析仪,附带您需要入门的所有内容。首先,您会得到一个手枪风格的探针,该探针通过短软管连接到外壳的底部。这配备了鼻锥,可提供非常准确的读数。但是,可以去除锥体以揭示可以通过小孔插入的较小的内部探针。有两个额外的软管,以防电缆损坏。甚至有10个额外的颗粒过滤器,还有一个可保持所有内容的硬性盒。

Testo 310

这analyzer housing is made of black plastic, with high-visibility orange hand grips. The back features built-in magnets for easy mounting on ducts and other machinery. This allows you to work with one hand instead of two. The display is backlit, allowing for good visibility in both light and dark conditions. It can measure temperature, draft, and the amount of O2, C02, and CO in the exhaust. You can cycle through these readings with a pair of arrow buttons, which makes operation fairly simple. Additional contextual menu keys allow you to perform additional functions. There’s even a print button, although no printer is included with the kit.

单元的前部有一个小缝隙,可通向内部冷凝水陷阱。为了排干冷凝的水分,您只需要向前倾斜分析仪即可。任何水都会简单地从住房运球。

Bacharach Fyrite Intech

Bacharach Fyrite Intech

Bacharach Fyrite Intech是为住宅炉设计的更强大的燃烧分析仪。除了与Testo Analyzer相同的读数外,它还具有燃料类型菜单。您可以在六种最常见的住宅燃料之间进行选择,并为每种燃料找到理想的测量值。诚然,这是您在图表上可以找到的东西。但是,拥有所有自动化的一切都变得容易得多。像Testo一样,Fyrite Intech具有背光LCD显示屏,因此您可以在黑暗的地下室中读取它。

Bacharach Fyrite Intech

车载存储使您可以保存10个完整的记录,包括所有测量。如果您需要更具体的记录,则可以使用随附的打印机创建物理副本。其他附件包括所有必需的电缆,三个颗粒过滤器和坚固的硬壳。

In addition to all this, the Fyrite Intech utilizes B-Smart replaceable sensors. These are pre-calibrated, and can be swapped out in the field. This means you don’t have to send the analyzer in to the manufacturer for re-calibration. Moreover, replacement sensors are actually cheaper than manufacturer recalibration. By using pre-calibrated replacements, you’re saving time and money at the same time.

现场代码Sox3

现场代码Sox3

Fieldpiece is a well-known manufacturer that specializes in testing equipment. Among other tools, they produce some high-qualitydigital manometers。这现场代码Sox3is made to be as affordable as possible. This means you get an analyzer and probe only. There’s no fancy carrying case, and no extra parts and pieces. That said, the probe and analyzer themselves are well designed, so you’re getting good value for your money.

SOX3测量排气中O2和CO2的百分比。它还测量烟道温度,过量空气的百分比和燃烧效率。也就是说,其设计有一个重大限制。它不能衡量CO浓度。您可以使用它来确保最大的CO2生产,这意味着您的CO生产应接近零。但这仅在理论上是正确的。实际上,时髦的空气图案会导致炉子部分不完全燃烧。如果是这样,您真的很想知道您的炉子正在推出一氧化碳。不幸的是,Sox3不会告诉您。

Sox3与Fyrite Intech共享的一项有用功能是O2传感器可更换。它甚至具有内置传感器,可以告诉您何时需要更换它。

Final Verdict

那么,哪种燃烧分析仪是最好的?在大多数方面,这将取决于您的需求。这Testo 310对于需要执行基本阅读的房主和专业人士来说,是一个不错的选择。它为您提供了二氧化碳,CO,O2,温度和草稿的读数,这是最重要的读数。不仅如此,鼻锥设计尤其精良。它将覆盖一个中型的访问孔,提供更好的阅读。但是由于它是可移动的,因此您也可以通过较小的孔进行工作。唯一的缺点是您无法获得诸如氮氧化物和二氧化硫等高级读数。

Bacharach Fyrite Intech是三种产品中最有价值的,但也是最全面的。它包括打印机,因此您可以轻松地记录工作的物理记录。还提供十读的板载存储空间,以及六个常见的加热燃料的配置文件。除此之外,该分析仪只是精心设计的,可更换的传感器可将停机时间保持在最低限度。

现场代码Sox3如果您只需要基本功能并且不想花费大量时间,则是最佳选择。这是测量温度以及二氧化碳和O2浓度的准则探针和分析仪。这足以使炉子或锅炉效率最大化,这是一个很好的起点。对于房主来说,这是一个可靠的选择,但是HVAC专业人员会想要一些具有更多功能的东西。
