[Gasification] energy for villages

 Dear Tom,
there are several firms in India, which offer ready to use indigenous and
Chinese electricity generators driven by internal combustion engines. The
i.c. engines run on some form of petroleum derived fuel (petrol, diesel,
kerosene, LPG or CNG). India generates annually about 800 million tonnes of
agricultural waste. The calorific value of our agricultural waste is about
2.5 times that of all the petroleum used in India. Therefore, we are trying
to find ways of substituting petroleum based fuels with fuels derived from
biomass. An i.c. engine can run on pyrolysis gas, producer gas, gas from a
TLUD device, biogas, or coal gas. Application of charcoal to the soil does
not have any beneficial effect in the area where I live. So, we do not
apply charcoal to the soil but use it as fuel. In the case of a wood
burning domestic cookstove, a lot of charcoal is left behind on the grate.
If allowed to burn on the grate, it does not produce a flame but it only
glows. Therefore, its heat does not reach the pot, which is about 10 to 15
cm above the grate. That is the reason why one needs a different type
of stove for burning the charcoal. We are currently testing a
stove, basically designed to accept wood as fuel, but in which the charcoal
formed by the burning wood is converted into coal gas. The latter produces
a flame when it burns.
Yours
A.D.Karve
