[Stoves] Alternative to charcoal

[Crispin Pemberton-Pigott]

Dear Alex

 

Cecil certainly does because lifespan is core to his arguments about
improving the experience of the owner. If a Keren stove lasts about 3 months
in Yogyakarta, 2 weeks in commercial use, then a stove that lasts 3 years
can justifiably be quite a bit more expensive.

 

Whether burning the char lowers the lifetime or not is dependent on the
materials and the temperatures. I think there is an assumption in the
tincanium stove producers that burning char is bad because their stoves
can't handle it. Other people make stoves that only burn charcoal so if they
are adapted to burn wood as well - no problem. The technology is not limited
to what people happened to use to build one.

 

Here is an Anglo Supra Nova (nominally a charcoal stove) burning 6mm wood
pellets TLUD style.



 

Here you can see individual preheated secondary air jets entering the wood
gas.



 

Here you can see the charred pellets being burned after pyrolysis is
complete. This is accomplished by opening the primary air door which changes
the air/fuel ratio on the primary side.

 

This unit is slightly cheaper than the Anglo Supra (a sort of Thai Bucket
which was itself introduced 30 years ago by Robert van der Plas and 'Tig'
Tuntivate, so it is rumoured). It has a working life of about 3 years
burning charcoal. Cost is $5.50 retail, much less at the producer.

 

Regards

Crispin

 

 

 

Crispin,
Do you think it is useful to place a value on the reduced life span of a $5
TLUD  when burning char compared to the same TLUD not burning the char?
Alex
