This mini-fireplace made from empty cans will come in handy in the garage, utility room, as well as when hunting or fishing. With its help, you will be able to cook food, warm your cold hands, and even warm your tent when the temperature outside is sub-zero.
Do-it-yourself biofireplace using alcohol from cans
Remove the labels from the jars and remove the lids. Apply markings approximately 3 cm from the bottom of the jar and cut with a grinder.
We wrap the can with fine metal mesh for repairing bumpers, mark the cut location, add 1 cm, cut it off and use it to make a lock, which, after rolling the mesh into a roll, we snap it into place.
For the next step we will need a jar slightly larger than the previous ones. Use a grinder to cut off the top circular stiffener rib. Stepping back about 3 cm from the bottom, cut the jar transversely to approximately the middle. Then we make a longitudinal cut from the top of the can to the center of the cross-section and slightly unbend the resulting sidewalls of the longitudinal cut.
We assemble the bio-fireplace in the following sequence: insert the mesh roll into the bottom of the smaller jar.We place a metal sponge inside the roll to remove heavy dirt and cover the top with the bottom of the second can.
We place the resulting structure in our improvised reflector, previously made from a larger can.
We use ethyl or isopropyl alcohol as fuel.
It is more convenient to refill our bio-fireplace using a medical syringe, drawing it from a container through a needle and pouring it into the lower bottom of a smaller jar.
Using a lighter, we ignite the alcohol vapor on the outside of the mesh and wait until our homemade fireplace reaches operating mode. It occurs when burning alcohol vapors heat the ribbons of the metal sponge red hot.
When operating such a fireplace, no smoke or odor is emitted, since its operation is based on the principle of catalytic combustion. At the same time, the temperature recorded by a remote thermometer at different points of the fireplace ranges from 100 to 400 degrees Celsius.
