[Stoves] stoves by the millions

[Crispin Pemberton-Pigott]

Dear Michael

 

Never assume anything, nor let others assume it for you, especially about
things that are complicated. Dr Goreau is quite correct that it is unlikely
that the stove would be durable but there are many things to consider. 

 

First it may not be necessary to last a long time. 

It may make a very good way to produce something that is otherwise only
producible from imported components.

It can be done by a very unskilled person.

It requires very little work.

It may be possible to mix refractory cement into the process (basically a
clay and cement mix) in some way. Perhaps as a liner put in afterwards,
getting an excellent bond on the 'biorock' (who invented that name?).

 

It may reduce the cost and increase the stability of a stove product by
reducing the need for metal to the combustion chamber only.

 

It may be possible to have a sacrificial element and a more expensive fixed
element.

 

The resulting ash/decomposition may be high value cement. Cement is
difficult to import and does not last long. The wood ash and burned calcium
might make a good cement substitute if the char is screened out.

 

Lots of possibilities.

 

Regards
Crispin

Dear Chrispin

 

Thank you for the edifying comparison and explanation on refractory issues.
Dr Goreau advise he believes biorock 

would not work in an internal stove application, unless we want to make
quick lime or use with betel nut. However a mesh

or wire frame for the external housing might work.
