In the world of thermodynamics, combustion analysis is an essential factor. You see, using this device, we can measure the efficiency of a boiler, furnace, as well as house heater.

In addition to efficiency, you can calculate the pressure, stack temperature, flue, and various other aspects that can be used in many ways.

Now, this might sound quite complex, but in a couple of minutes, you will understand every detail regarding the topic as we are going to show you — how to use a combustion analyzer.

And it is very critical that you have a precise knowledge of the subject. So, we suggest that you complete the entire course since all the necessary information shall be provided to you right here.

What Is a Combustion Analyzer?

What Is a Combustion Analyzer

Before we get into the topic of usage of a combustion analyzer and the places that you could use it on, you must know what a combustion analyzer is. So, let us start with how the device looks.

Now, it is an electronic device that contains a display (which shows all the data), a long metal attachment that takes the measurements, and various buttons, which you will use to operate the device.

If you want a more detailed picture, then you could visit the combustion analysis as it contains a vast array of information on the topic.

How to Use a Combustion Analyzer?

We are splitting this into two sections. In one of them, we shall be discussing how to use these tools on almost all varieties of machines, and on the other section, we shall be talking about how to use these on a specific type of machine, the boilers.

Section 1: General Use

Using a combustion analyzer might feel like rocket science at first; however, if you follow these steps, then the procedures will turn out to be much more effortless.

Step-1 (Check If You Are Missing Anything)

Check If You Are Missing Anything

Now, the very first step of using such a device is to ensure that you have everything you need. Here is a list of the things that you must have.

  1. A lithium battery
  2. Probes with a cone on the edge
  3. Hose
  4. Silicone tubing to measure the pressure
  5. A few extra particulate filters
  6. A USB AC power supply
  7. Pressure plug
  8. Protective casing or cover
    Now, there are lots of other utensils that you can have in your arsenal, but we suggest that you make sure you have the things that we have listed above prior to using the device. Also, ensure that it comes with a pre-installed condensate trap.

Step-2 (How to Use It)

Well, first and foremost, the thing that you need to do is attach the device to any fire operated machines. And there is a reason you do this.

You see, the device is a very delicate piece of apparatus, and you must not do anything to disrupt the calculation process of the tool.

So, there is a magnet that shall allow you to attach the device and the battery to the machine. Then, connect the probe to the thermal couple connecter, and then you have to wait for it to go through its diagnostic warm-up (taking measurements of the fresh air). The analyzer is doing this to reduce the chances of an anomaly.

After it is done, the device is ready to be used. However, before you can use it, you have to drill a small hole in the flue chamber of the machine you are measuring. By doing this, you can effortlessly attach the probe inside the flue chamber or pipe.

Once you are done with all these, all you have to do is select the format of the measurement that you are going to take. A combustion analyzer offers you data on:

• Oxygen, Carbon monoxide (with any oxide of nitrogen), and Carbon dioxide
• The draft and pressure
• Stack temperature (flue, along with ambient readings)
• Combustion efficiency and tertiary air
• Undiluted Carbon Monoxide (Carbon Monoxide in a vacuum)
• Ambient carbon monoxide rating

So, you can see that the combustion analyzer can give several readings, and you get to choose the one that is required at the moment.

Step-3 (The Result)

Once you are done, you should get a measurement of the efficiency and various other aspects of the machine that you are measuring.

Section 2: Boiler

Well, for a boiler, the steps that you have to follow are quite similar to the ones that we have presented in the previous section.

However, for boilers, you need to select a variety of gas that you intend to work on, and it doesn’t have to be fuel as you might even choose wood or almost any material that is combustible.

Now, unlike a furnace, boilers generally use PVC pipes, which are a tad more sensitive. Therefore, when you are drilling a hole into the pipe, you have to make sure that you are not drilling too deep into the pipes.

Where Do We Use It?

We use these marvelous devices in several key areas. Here are some of the noteworthy places where you can use them:

  1. Using these tools, you can accurately measure whether the boiler, furnace, or heater is doing its job properly.
  2. It can be used to estimate the ambient CO limits, max CO boundaries, and various other emission data.
  3. Use them to determine whether your boiler is undergoing complete combustion or not.
  4. You can assess the efficiency of the boiler when operating different kinds of fuels and burners.
    In short, there are many sectors where you can use these devices, and by using them, you can regulate numerous aspects of your boiler, including its efficiency, pressure, temperature, etc. Thus, drawing out a decent data from your fire-operated machine can be an effortless chore using a combustion analyzer.


So, if you want to us to summarize the article, you can use these analyzers for boilers, and all sorts of different heat-using machines. And by applying them, you can achieve multiple data on diverse features of your machine.

Let us know if you could learn how to use a combustion analyzer from our article.
