Hi all - I'm new here, and already feel welcome.  The place reminds me of a black and white well worn copy of whole earth catalog of my dad I'd browse through - good memories!

I've signed on here becasue I've been researching rocket stoves for cooking for a couple months, and then stumbled across the butt warmer version.  The differences are really interesting.

Understanding that my goals are only for the purpose of cooking, not heating, I'm wondering if the idea of drawing the gases back down the barrel from the insulated rocket chamber would be useful?

Does the draw back downward after the insulated chamber aid in combusion, making a cleaner exhaust gas?  I can see why you need the gases to come down to get to the level where you'd put them through the bench, but I'm wondering if there's a role for that geometry in a cooking?  Thanks!

How about drawing the gases down around an oven?
Sort of the reverse of an oven above a fireplace, or beside the firebox in a cooking stove.

I like the oven idea - as a secondary place to cook, dry out items, etc.

thanks for tossing out that idea!

no the high combustion temp and high availability of oxegen make for the clean burnthats why the first bit is insulated to preserve high temps for complete combustion

Thanks Bruce...

What is the the purpose of the outer barrel that pulls the gasses back down after the ride up the insulated combustion chamber? 

I'm guessing that it's only the get the gasses back down to a "bench" level.  If I'm building a stove only, then I don't think the outer chamber is needed...

Do you agree?  Because now that I'm typing this, I'm wondering if the outer chamber might heat the inner combusion chamber and thereby aid in making combusion as complete as possible...

The butt warmer rocket stoves just seem to burn so much cleaner than the regular "cook-pot-on-top rocket stoves" and I'm trying to figure out why.  Maybe it's just the benifit of not having the smoke coming up around the pot in your face...
 
It's a pleasure to see superheros taking such an interest in science. And this tiny ad:
