In the pilot project in Deganga, the earliest stoves have completed over 
4 years of virtually daily usage (with annual confirmations by the 
carbon credit verifiers).   This is with maintenance and repairs.   The 
major parts have many years of life ahead of them. The repairs are on 
the grate and on the fuel chamber (innermost cylinder).   The project 
purchases the produced charcoal, so the users are quite good at dumping 
out the char at the end of the pyrolysis stage, thereby helping protect 
the grate and lower sidewalls.

The fuel cylinder has a "sacrificial cylinder" that is inside the main 
wall of the fuel cylinder.   When it is showing stress, it is removed 
(one screw) and inverted so that the less-stressed upper portion becomes 
the bottom area.  I am asking the project implementer (MB) about the 
frequency of the repair work.  The cylinders are produced with seam 
welding of stainless steel sheets. Look good and hold up well.

The stoves are assembled at one location (with quality supervision) from 
components from 5 different suppliers whose components are clearly 
comparable with each shipment.   There is surplus production capacity in 
the Kolkata area to greatly expand the number of pieces of each component.

I agree.  Just need to find the time to do the write-up.   I hope to do 
it before ETHOS.   By January 2018 the project will be passing 50,000 
stoves in use, and (I anticipate) that the number of stoves per month 
will be over 4000, with new expansions of the project coming on-line as 
fast as funding will allow.   (I will discuss funding issues in a later 
message.)
