[Stoves] 2-burner rocket stove

[Crispin Pemberton-Pigott]

Dear Kevin

There is a stove found in Sulawesi which is designed to be able to do that, as well as roast meat on sticks - they call it saté (shishkebab). This is a zero cost stove made from clay.  Note that the gas exit channels have the effect of choking the exhaust rate to match the required air demand.  This is the easiest way to control a high excess air level.  High EA cools the pot.

The fire can be pushed under the pot, or raked back (esp as hot coals) to heat a second pot or roast meat or veg on sticks.  The top of the stove has an interesting shape.  The slots allow the gases to exit, and the pot rest is a full circle to prevent runaway fire (a generic problem with rocket-type stoves).

It is made from unfired clay but you could fire it if you wanted to.

Regards
Crispin

(I don't think I've posted about this, yet.  If I have, my apologies.)

Any rocket stove can be turned into a 2-burner rocket stove by putting bricks in front and placing a second cookpot directly on the bricks (no pot rests).  The fuel and fire are moved out of the rocket stove and under the new cookpot.  The draft created by the chimney in the rocket stove will pull the fire into the rocket stove to heat the upper cookpot.

Two cookpots heated with one fire!  More efficient and less smoke per dish.
