Funky piece of camping gear

I'm not convinced by this at all . To get a good heat from a stove and especially to initially light it the dimensions would have to be bigger imo . Packaged size is only 8 inch by 5 . That would be fine for a petrol stove or meths one but i dont think would be suitable for biomass although i may well be wrong . There are similar ones which are a good deal bigger ( which also power fans ) that i think would be better for cold environments

It boils 1lt of water in about 4 minutes. Good enough for me!

Yeh , but it could take 20 mins to get it started ! I've seen bigger versions of this and it was a headache to get it started . I can only imagine a much smaller one would be a migraine to start efficiently

Have a look through their website and on YouTube, it doesn't seem to have a problem lighting? The fan starts very quickly forcing air to the fire.

Will do Paul . I'll check that out

It looks well engineered for the price but no way would i replace my trangia for that

Is the burn chamber not designed to be a gasification stove?

 

The initial combustion is as a pyrolysing fire, only enough air gets to the pyrolysis zone to sustain it, the pyrolysis offgas from this is what burns in the flame. As the pyrolysis front gets to the bottom then it works as a normal updaraught fire, to keep it in gasifying mode the primary air velocity and hence volume has to increase significantly. The problem is that the temperature in the can goes up from about 600C for pyrolysis to over 1100C. Steel cans can just about survive the lower temprature but will spall off iron oxide at the higher temperautres and even stainless won't do much better.

 

The interesting thing with these TLUD devices is that they won't work with wood withmoisture content of more than about 25% but with dry wood they produce charcoal if the fire is snuffed as the pyrolysis zone reaches the bottom.
