Concrete rocket furnace - it won't rust behind them

Oh, how nice it is to cook and eat outdoors, in the garden, at the dacha... Small metal stoves are often used for these purposes. But this is not entirely convenient, since after use they need to be removed indoors from rain or from various metal thieves. Another thing is a stove made of concrete - you don’t have to hide it, no one will need it for sure... You can easily leave it to spend the winter in an open space. All these advantages prompted me to make a rocket stove from concrete.

Various garbage constantly accumulates at a summer cottage: small branches, pine cones, flammable household waste, etc. All these materials can be used as fuel.

What you need to prepare

An old plastic bucket of building materials with a capacity of approximately 20 liters, any cement-based mixture and a 10 cm piece of plastic pipe, the length should be greater than the sum of the diameter and height of the container. To pour the solution, you need to use a trowel and a trowel; the pipe is cut with a circular rotary cutting saw. A plastic bucket is cut with a hacksaw for metal.

Manufacturing technology

Place the pipe on the sawing machine and cut one end at a right angle and the other at a 45-degree angle.Two such blanks are required. The length of one should be 8-10 cm greater than the radius of the container, and the second should be the same amount greater than the height of the bucket.

Place the pipe vertically and draw a circle on thick paper; in this way, a template is made for drawing a hole in the bucket. Use a knife to cut out a circle.

Place the template on the side of the bucket and draw a circle. The distance from the bottom is about ten centimeters.

Drill a hole with a diameter of 3-5 mm on the line, cut out a large circle. Insert the cut into the hole with the oblique cut inward. In the future, the second piece will be adjacent to it, at the junction there is an angle of 90 degrees. Inside the formed hole there will be a combustion chamber for small branches.

Take out the lower pipe, pour dry cement-sand mortar onto the bottom, and insert it into place.


Pour water over the mixture until completely absorbed.

Then place the vertical pipe, aligning the cut ends exactly. Pour the mixture into layers approximately 10 cm thick and moisten with water. Once the container is full, level the top surface with a trowel.

Allow about an hour for the solution to set and carefully remove the plastic pipes. Leave the container overnight for the solution to set.

Remove the concrete structure from the bucket by using a hacksaw to cut the plastic and remove it. Use a hammer and chisel. Do not damage the concrete; if it has not gained sufficient strength, then give it more time.


Test the functionality of the stove by lighting a fire in it. Narrow pieces of ceramic tiles can be used as supports for the frying pan.


Everything is fine - start cooking.

Conclusion

One of the significant advantages of such a stove is its strong draft, which allows the use of raw twigs.
