Dr. Rajvanshi: cc stoves and adding "bochar-production" Thanks for sending us this report. A few questions
a. This work was done in the mid '90's. What has happened recently with this or similar equipment in India or your part of India? Can one now buy such hardware? b. What caused NARI to design a pyrolyzer rather than a combustor? c. In the Abstract, you said the char "... .can be used as a soil conditioner ." This would have been very early in the history of what we now call "biochar". Was there then a market near Phaltan for such? Now? d. Your economics section does not show a price for char. Can you guesstimate the relative value then and now for the char? Congratulations for what appears to have been a successful design - ahead of its time..

I’m thinking the reason is that to convert to electricity one needs 1) a very clean syngas 2) an expensive motor and 3) costly up-keep. The generator is a onetime purchase with low maintenance. So why not use a steam engine to convert the flame to electricity? Perhaps not as efficient but all you are doing is heating water so the gas need not be as clean as when drawn into an internal combustion engine.
