[Stoves] Looking for a stove designed for larger amounts of biochar

[Anand Karve]

Dear Stovers,
we are currently using 200 litre steel barrels for charring sugarcane
leaves into charcoal. Our kilns work on the TLUD principle. Since
sugarcane leaves are light in weight and difficult to transport, we
send our kilns to the farm where they are harvesting sugarcane,
convert the dry leaves into charcoal and bring the charcoal back to
our briquetting facility. The gaseous part of the leaves is burned and
exhausted. Being an ambient operation, we cannot harvest or use the
energy generated by burning the gaseous fraction of the biomass. But
since sugarcane leaves are in any case burned in the field itself,
nobody mourns for the loss of energy.
Yours
A.D.Karve
