Rocket chiminea?

Hi everybody!

Well guys, you're all called to the rescue. I have that idea going round in my head, since a while back.

Have you ever seen a "chiminea"

www.google.fr/search?q=Chiminea&safe=off&rlz=1T4SAVJ_enFR550FR551&tbm=isch&tbo=u&source=univ&sa=X&ei=wnqzUofXJ6eb0QX30oAI&ved=0CDEQsAQ&biw=1216&bih=515

Some kind of mexican stove.

What i would like to do is, narrow the chimney as much as possible at the root of the chimney, above the bulb, and then expand into a cone. All insulated, like a heat riser, bulb firebox and conical heat riser.


The big question i have for all of you, is, what material? How would you go about making it?


Thanks a lot guys.


I am also wondering what would be best straight wing nose venturi? Or may be more cone in cone out venturi? The point is, making it as narrow and hot as possible, so no unburned particle can excape. And whatever the amount of fuel below, the things adapts. The hotter it goes, the more draft it produces.


Thanks.

Max.

The turbulence could be alright. Addition of fresh air just before the venturie widens is a problem, as is the time factor. The three T's plus air.

A year or so ago I saw an online photo of a sunken outdoor seating area with a chiminea as part of the bench.  I haven't been able to find the photo.  The set up was rather cool.  Chimineas are similar to kivas which are forms of masonry stoves - both based on clay mass.

Can't wait to see what you come up with.
