We normally surround a burn tunnel with insulative material that can withstand lots of heat: superwool, perlite, pumice, etc.
I've done a postmortem of a failed combustion chamber and for the first two seasons it seemed great...I'm still not sold on the concept over the long haul until I see a teardown of one that's been running for at least a couple of years in daily service.

I dont think he has had it officially tested in any way or if it is in any way a better performer than Peters Batch Box that has been extensively tested and the detailed plans are free?
I have to agree with Fox James, and add, If anyone on this "permies" group finds any of this to be true, Please do post....but in the mean time, I don't think the basic principals can't be done, but would love to be proven wrong.
Such as, I think he is saying
-his green wood burns as good or better than dry wood, humm
=his mass holds more heat for less weight than anyone elses
= his riser is better than anyone else's
- in others videos he has reported 2500-2700 degree's F but can the the rest of us get that? hummm.....
- 4 inch flue pipe, really?
There is always hope, always...

It is denser than soap stone. when cured at high temperatures above 1500 degrees it's fracturing strength is almost 20000 lbs. per square inch. Its normal operating temperature is between 3-4 thousand degrees. I regularly record temperatures of 2800 degrees in the back of my stove.
I think you've invented something very interesting. It has many possibilities. And because it's lightweight, it could even be integrated into travel trailers and such. Or a portable unit for hunter's tents, emergency shelters, disaster relief, ...the list goes on.
Darwin Honeydo wrote:Hard woods will maintain the burn box temp between 750C and 900C which is the sweet spot where (HTSE) happens.
But respectfully, I suggest that if you promote the HTSE angle, and these temperatures in particular (sans catalyst), what you've achieved will be hacked to death by the howling mob of the wider Internet. The feedback received here has been thoughtful and respectful. That will not apply elsewhere: it paints an easy target for people to shoot at. There is no net energy gain. Why insist on this?
Douglas Alpenstock wrote:Interesting! That's a very cool (hot) stove you've put together. How long do you think the aircrete will hold up?
I'm not entirely sure about the high temperature steam electrolysis idea. I thought that only started to happen above 2000C unless a catalyst was involved. That's higher than the melting point of steel.
