Bushcraft - Bushbox LF Titanium Outdoor Stove

Our Bushbox LF in the ultra-light titanium version! Weighing only 270g (315g with pouch). The Bushbox LF Titanium comes complete with our durable outdoor pouch.

The Bushbox LF (large, foldable) is, so to speak, the missing link between the Bushbox and the Bushbox XL and combines the best of both worlds: very small, yet foldable, and with a draw as good as a large one. Naturally, the Bushbox LF is manufactured with the same special and unique hinges as the Bushbox XL: this extremely sophisticated hinge technology ensures that the hinges can never stick. Like all Bushcraft stoves, the Bushbox LF is made entirely of pure titanium in Germany and is multi-fuel capable (operation with wood, Esbit, Trangia, etc. possible).

For users who wish to use the Bushbox LF Titanium in combination with Trangia stoves, we recommend ordering an additional trivet set.

Dimensions: 14 x 10 x 1.2 cm (folded), 14 x 10 x 10 cm (unfolded)
Wall thickness: 1 mm

Notes on hobo stove firing

Soot/smoke: Soot formation always means: lack of oxygen and combustion temperature too low. Fired correctly, no significant soot can be produced with a Bushbox XL or a Bushbox LF. Soot and smoke are always signs of incorrect firing.

Chimney effect: The basic principle of a hobo stove is the chimney effect; our stoves are additionally built in such a way that the Coanda effect can also come into play more effectively. Both physical effects require that air supply is guaranteed so that an airflow is created which supplies oxygen, whereby on the one hand very high temperatures are reached (up to 800 degrees) and on the other hand (and this is the most important point) the heat is carried upwards by the airflow and reaches the pot almost completely, instead of radiating out the sides.

Optimal operation: A hobo stove is operated optimally when there is relatively little fuel in the combustion chamber. The wood then burns very hot, the heat is only partially transferred to the outer walls, smoke and soot cannot form (if soot does form, it burns off without residue), and there is almost no warping, as there is no localized heating of the side walls. If the hobo stove has been fired optimally, there will also be almost no residue or ash, only a tiny pile of very light, almost white ash.

Care should also be taken to avoid "yo-yo firing" (constantly changing temperatures) and extreme temperature differences (quenching in cold water).

However, in many of the videos circulating on the internet, the boxes are stuffed to the brim and you can sometimes see a flame meters high shooting out of the hobo stove. But that leads to the following problems: The chimney effect is severely restricted, the combustion temperature drops to around 200-300 degrees, and smoke and soot are produced. Burning material touches the side walls in many places, which leads to strong uneven heating of the side walls and at the same time to the transfer of a lot of energy to the side walls. Heat islands or a strong temperature gradient between the top and bottom are created, with which another physical effect can develop optimally, namely warping.

Improper use: Many misunderstandings also arise because some of our customers use the stoves as a mobile campfire and subject them to hours of "yo-yo firing" and temporary overfiring. Although our stoves have to prove that they can withstand such things and can still be folded afterwards or remain fully functional, no normal steel can withstand this permanently without damage (any more than quenching in cold water).

Warping: Warping is a physical phenomenon that is unavoidable when metal is heated unevenly (and therefore expands unevenly). Slight warping is therefore unavoidable and normal. However, all our hobo stoves are designed in such a way that warping only occurs to a very moderate extent during intended use and the function of the hobo stove is not impaired in any way.
