Bushcraft - Bushbox XL Titanium Outdoor Stove

Our Bushbox XL in the ultra-light titanium version! Weighs only 490g (540g with bag). Packed dimensions (folded in the bag): 21 x 17 x 1 cm (without bag 19 x 12.5 x 1 cm). The parts subject to particularly high thermal stress (base plate, pot supports) are made of stainless steel. The Bushbox XL Titanium comes complete with our durable outdoor bag.

For users who wish to use the Bushbox XL Titanium in combination with Trangia burners, we recommend ordering an additional pot support set.

Notes on wood stove operation

Soot/Smoke: Soot formation always indicates a lack of oxygen and too low a combustion temperature. When fired correctly, a Bushbox XL or Bushbox LF will not produce any significant soot. Soot and smoke are always signs of improper firing.

Chimney effect: The basic principle of a wood stove is the chimney effect; our stoves are also designed to allow the Coanda effect to be more effective. 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 at the same time (and this is the most important point) the heat is directed upwards by the airflow and reaches the pot almost completely, instead of radiating out the sides.

Optimal operation: A wood stove is operated optimally when there is comparatively 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 because there is no localized heating of the side walls. If the wood stove has been fired optimally, there is also almost no residue or ash, just a tiny pile of very light, almost white ash.

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

In many of the videos shared on the internet, however, the boxes are stuffed to the brim, and you can sometimes see meter-high flames shooting out of the stove. But this 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 strongly uneven heating of the side walls and at the same time to the transfer of a great deal of energy to the side walls. Heat islands or a strong temperature gradient between the top and bottom are created, which allows another physical effect to develop optimally: warping.

Improper use: Many misunderstandings also arise because some of our customers use the stoves as a mobile campfire and expose them to hours of yo-yo heating and intermittent overfiring. While our stoves have to prove that they can withstand such treatment and still be foldable or remain fully functional afterwards, no normal steel can withstand this permanently without damage (any more than it can withstand 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 inevitable and normal. However, all our wood stoves are designed in such a way that warping only occurs to a very moderate extent during proper use and does not impair the function of the stove in any way.
