[Stoves] COMPULSORY VIEWING!!! link from Re: The Aprovecho Newsletter - December 5th, 2014

[Huck Rorick]

Paul, Dean & List,

 

Thanks.

 

I was especially interested in the sunken pot rocket stove because it incorporates a chimney.  It looks a lot like some of the ways we are trying to incorporate a chimney with the Champion or other TLUDs for our project in Cameroon.  From my viewpoint a chimney is essential to a wood burning stove, even when it is “super clean”. In California hoods are required for natural gas stoves.

 

Are the details of these stoves something that Aprovecho wants to keep private?

 

I’m frustrated with the fairly common description as “super clean”.  It seems like every manufacturer says that about their stoves.  It would be nice to have some more exact measurement (and I guess there is a lot of debate about what the measures should be).

 

Anything about costs?

 

Huck

Stovers,  

Absolutely interesting and important is the just-released 8-minute video from Aprovecho.   Especially the final 2 minutes (starts at 5:50) need to be seen by all serious stove developers.  There ....



...... ARC unveils five new super clean-burning cookstove prototypes that will be considered for mass production in 2015.

Please watch on YouTube at:

This is the first time these stoves have been openly shown, even though showing only a few seconds each.   Of exceptional note is the natural draft TLUD-ND stove designed by Kirk Harris!!!

One error (a very common misconception) is in the video at 6:46 concerning the Aprovecho "Top Loaded Forced Air stove", putting it into a category with forced air TLUD stoves, saying that the "TLUD-FA design [that] is used in the Philips, BP, and Biolite stoves."  These four stoves use the migratory pyrolytic front (MPF) of the TLUD technology only at the beginning of burning, and then the fire is in the bottom (bottom burning with additional fuel added on top, as in standard (not MPF) up-draft gasifiers) with forced primary air blowing onto the charcoal located there, creating forge temperatures that require special materials (ceramics, cast iron, special metals) to avoid fast damage to the fuel chamber.  We do not know yet what is inside the fuel chamber of the Aprovecho "Top Loaded Forced Air stove".   These are cost factors.

This is all great progress!!!.   Congratulations Aprovecho!!!!    

We will want to be comparing the cost of manufacture (or the sales price) of all of these stoves.   And the announced field trials of these 5 stoves in 6 countries will be of great interest.   

The first 6 minutes shows the sophistication of mass production of SSM company in China.   In the world of cookstoves, this is big business.

And  we will see these 5 stoves (among others) at the ETHOS meeting 23-25 January 2015 in Seattle area.

Enjoy!!

Paul
