Process of Making a Catalytic Burner / Tutorial

Today, I will tell you about the process of making a catalytic burner. This is a catalytic heater that does not have an open flame outside its casing. So, we can observe the fire, but it will never burst outside! Therefore, this burner is safe and actively used in hiking trips when it comes to heating a tent or a person outdoors, even in strong gusty winds!

1. Metal cans
2. Stainless steel mesh (as fine as possible)
3. Metal sponges for dishwashing
4. Medical alcohol or fuel for bio fireplaces. (This is the only non-toxic fuel that can be used indoors without harm to the body.)

We will be using two tin cans. We measure the dimensions of the can's circumference and transfer them to a piece of paper. 

Then, we take a metallic, preferably stainless steel, mesh. The finer the mesh, the better and more efficiently our heater will work!

Using the paper template, we cut out the metallic mesh, keeping an eye on all the height dimensions provided by me. It is essential to seal the seams in the mesh joints well so that catalytic vapors only come out through small holes and immediately ignite. Otherwise, your flame will burst outside, the project's essence will be disrupted, and you'll end up with a regular open flame that has nothing to do with the catalytic process. 

As fuel, you can use medical alcohol—it does not emit toxic gases and is excellent for enclosed spaces. The only thing, like any flame, it consumes a bit of oxygen depending on the fireplace's burning duration. By the way, it's very similar to a home bio-fireplace; it also uses alcohol with some added flavoring agents. And there, of course, it's a regular open flame, not catalytic like ours.

Fill one end of the mesh tube with a metal sponge for dishwashing. Part of the catalytic and vaporizing process will take place there due to heating and evaporation of the liquid.

What is a catalytic burner?

Catalytic alcohol burner is a device for burning alcohol using a catalyst. It differs from regular alcohol burners in that it employs a special substance (catalyst) that helps alcohol to burn more efficiently and safely without producing an open flame.

The operation of a catalytic alcohol burner is based on chemical reactions occurring on the surface of the catalyst, allowing alcohol to burn without a visible flame. This makes it convenient and safe for use in various situations where controlled and effective heat provision is needed. Additionally, such burners can be particularly useful in places where an open flame may be undesirable or hazardous.
