[Stoves] Crispin´s kiln-was Re: Traditional Charcoal Making

[Crispin Pemberton-Pigott]

Dear Kevin

Agreed in principle. There will have to be at least 2 kilns minimum at each
site no matter what because it is probably not possible or worth the risk to
put 500 stoves in a single kiln at a time.

I must say that running a continuous operation is really difficult to keep
going for any length of time in a low tech environment.  I am really
cautious about recommending it but it definitely is energy efficient.

The Hoffman kilns in Maputo are typically 24 chambers necessitated by the
long heating and cooling times needed for bricks.  The exit temperature to
the stack is below 200 C, even as low as 80.  Pretty impressive!

In practice I think it will be possible to dry fuel using waste heat, fire
mostly with biomass and have some form of electric topping off standing by.
It might be a strange kiln but we are going to build them, not order off the
shelf so what the heck...

Thanks
Crispin

If Crispin has a volume market, the best would probably be a Three Kiln 
System operating in rotation:
