Secondary combustion is also known as secondary burn. The main purpose of this item is to boost the heat output and increase the efficiency of your traditional fireplace. There are also other benefits of secondary combustion like preventing blackening, reducing emissions, and more. Okay, you can see the entire process later but for now, let’s have a look at the process of making secondary combustion.

We have taken an old log burner stove for an upgrade. This is pretty old and needs to be clean up first. So, we focused on that part before diving into anything else. There were lots of ashes and burnt woods; we took them out properly. The chimney also required some cleaning up, and so we cleaned that too. Once everything is cleaned up, you will have to focus on installing secondary combustion

The Steps of Installing a Secondary Combustion

Step 1

Now, we will take out the door and drill some holes in it. This will allow us to install the wooden combustion in it. At the entrance spot, we have made three 12 ½ inches holes. We are gonna install the steel pipes in it. It will be the main setup, and that’s why we have used 10mm thick pipes in it.

Step 2

Next, we have taken a wooden log and created holes so that it can pass the air. You can use a different drill bit if you want or use the same drill for making the holes.

Step 3

After that, we have to improvise the jig to attach a nut to the pipes. You can simply use a bearing to weld the arms properly. Once you weld the nuts inside the short pipes, check properly if everything is properly set or not.

Step 4

Now, use a square pipe of 60/60 mm dimension for making the base of the combustion. Then create the holes inside of it. We have already made the holes based on the size of the small pipes.

Step 5

Once you install the small pipes, close the air dispenser properly by welding the sides. Make sure to create some air gaps and a small gap at the bottom of the combustion chamber. It will help you to prevent the smoke from the front glass and keep it clean. These small holes will also help to keep the air clean.

Step 6

Now that the design of the combustion is complete, you have to install it on the stove. We have already created some holes by using the drill and going to use them for the attachment. Take your combustion chamber and attach it to the door by using the drill spots. Once you complete the installation, your stove is ready to use with
