Using Caldera Ti-Tri stove as a wood gas stove is just one of the
options to use this stove. The Ti-Tri can use other fuel types too.
Read here on all the options the Ti-Tri got...
The basic design is a cone that serves both as the windscreen and as the pot holder. This makes a very efficient system since the pot absorbs most of the heat, and no heat is wasted. The Ti-Tri is made of Titanium (hence the Ti), and therefore, it can withstand fire based on wood. This enables you to run it on few fuel types (wood, alcohol, Esbit) and not just on alcohol like the simple caldera cone.
Wood gas is when you burn wood, but instead of just letting it burn, you burn it in a special stove that gasifies the wood. These stoves heat up the air inside it using a double wall and blow the heated air back at the top of the stove. It is much more efficient than simply burning wood. As a consequence, for a given amount of wood, you can get much more heat. Read here some more on wood gas stoves.
In order to use Caldera Ti-Tri as wood gas stove, the folks from
Traildesigns add some nice feature - you can use the cone as a wood gas
stove in no time.
In order to do so, you simply locate the upside-down cone (the inferno) inside the big cone. You place a mesh underneath the small cone, and you get a structure that can gasify then wood rather the just burn it.
Here is how you set the whole thing up:
The structure you get keeps the basics of any gasifier:
It allows air to flow from below the burning wood.
It allows air to flow through the double walls and heat up
It lets the heated air to flow buck just above the burning wood.
The tricky part with wood gas is to get the right holes on the right places. Not too small, not too big, so you won’t choke the flames or get to much wind in. Traildesigns made this stove just perfect for that.
In the clip below, I'm boiling two cups of water, using the Caldera Ti-Tri as wood gas stove.
On this video, It took me around 6 minutes to boil the water once the fire was going steady. Naturally, this timing varies a lot depending on the weather, the wood you use, the pot you use, the water temperature, etc. This test is on sea level, weather around low 80s, water temperature something on the 70s. I am using a Snow Peak Titanium Trek 700 pot.
I think that the guys that designed the Inferno did some nice job.
There aren’t to many options of buying backpacking wood gas stoves out on the market. Let alone if you want a version that is so light.
