Dome Flame DIY
Hello everyone! Today, I want to show you how to easily make a DIY burner. This burner can be useful in everyday life — at home, in the garage, or anywhere else where you need to heat food, light up a room, or keep warm.
Supplies
Two end caps 1/2
Metal sleeve 1/2
Adapter coupling 1/2
Copper tube 2-3mm
Evaporator-drier for a refrigerator (25 g)
Liquid
To start, I want to show you what’s inside a refrigerator drier. It contains granules like these, which absorb liquid very well. For example, if you pour water into them, it will evaporate five times faster than if you just pour it into a glass. This is a great idea for building today’s burner and improving its efficiency.
We drill six holes in the lid. First, I make 1 mm holes, and then I enlarge them with a drill bit of the appropriate size to match the outer diameter of the copper tube.
We make three rings from copper tubing. Each ring should have a slightly larger diameter than the previous one. Then, we fix them in place as shown in the video. Please watch the video for more detailed instructions so you can understand how to properly press the tubes into place.

By the way, to properly seal the connections, we’ll need high-temperature silicone. I designed an excellent accessory for a 5 ml syringe that makes it easy to dispense silicone or other liquids. This tool allows you to dose and dispense even the thickest mixtures through thin needles, which would normally require significant effort.
Since I don’t have a 3D printer, I ordered the print from a trusted website, JLC3DP. They did an amazing job — delivered quickly, provided high-quality printing, and charged a reasonable price. They also offer great discounts and coupons for first-time users. I’m leaving a link where you can get an additional bonus.

We fill the syringe and pour the liquid into the capsule. The amount of liquid is calculated individually. In my YouTube video, you will find detailed instructions on how to calculate it. After that, shake the capsule well, and about 30 seconds later, when you open the holes, you’ll notice that the liquid is gone — it has all been absorbed. At the same time, the process of vapor release begins.
We assemble the capsule, insulate it, and apply high-temperature silicone to the threads. Then, we securely tighten the cap and proceed with the first testing.
This burner can operate in different modes and with varying flame intensities. For example, if you close the tubular dome, the evaporation will occur much faster, and by creating high pressure, the flame will become turbocharged and reach very high temperatures. If you spread out the dome, the flame will be of lower temperature but thin, long, and beautiful. It’s up to you to choose the flame temperature and shape according to your needs. This will also affect the burn time: the higher the flame temperature and turbocharging, the shorter the burn time.
