Juntos Stove pictures

["Paul S. Anderson" <psanders@ilstu.edu>]

Stovers,

By popular demand (2 requests), I am sending you 3 low-resolution photos of 
the Juntos (Together) stove.   Each is 8 or 9 KB (small for e-mail 
purposes).  (From my digital camera to my computer to you, so there should 
NOT be any virus worry.)

This is actually the "improved" version developed after the success of the 
initial trial with simple tincanium "dog-patch" technology.

Be sure to match the explanation with the numbered photo.

Photo # 572:  The lower part of the Juntos stove.

A.  The cubical box on the left could be made of any stove material (metal, 
brick, mud) as long as it has the flat top (for supporting the gasifier 
unit) and has a hole in the side through which the gasifier is 
inserted.  The BOX does NOT need to be air tight,  in fact, it has holes in 
the lower sides so that the air for secondary combustion can enter.

Still on # 572:  B.  The gasifier is sitting on the right side.  It is a 10 
cm (4 minch) diameter tin can (in this demo model) with an "air-pipe" 
coming out the side to let the primary air enter into the bottom area of 
the can, which is open at the top.  The photo shows the top "plate" that is 
used to support the can when placed into the box "A" .  There is also a 
vertical "plate" that forms a simple seal (no need to be air tight) up 
against the side of the box "A".  You can see the simple handle for 
gripping the unit.  It is hard to see the small "foot" at the left end of 
the bottom of the vertical can.  The foot is only to hold the unit upright.

What you cannot see are about 8 holes (each about 7 mm diameter) drilled 
about an inch (2.5 cm) down from the upper lip of the can.  That is where 
the secondary air enters into the can.  The air comes FROM the chamber of 
the box "A" where the air is pre-heated by the heat of the gasifier can.

Photo # 575:  Shows the gasifier inserted into the box "A"

Photo 580:  Addition of a simple "rocket-stove-style" upper unit into which 
fuel can be added in the side hole.   There is a wire grate / mesh to keep 
that fuel from falling down into the gasifier unit.

For this experience, the temperature was about 2 degrees C (about 35 
degrees F).

NO indication that pre-warming of the PRIMARY air would have made much 
difference.
