The best rice-husk burning stoves I know of are the ones based on the
tremendous work of Alexis Belonio. Paul Olivier' s work in Vietnam has
taken rice-husk burning stoves in the household-size range to another
level, uncomparable with natural-draft stoves like the Mayon Turbo,
LoTrau or whichever. Paul has generously shared a lot of his work on
this list in the last days, so you can look more details up from the
links provided there or consult the section on rice-husk burning
gasifiers, pages 43-48 of the manual microgasification http://www.gtz.de/de/dokumente/giz2011-en-micro-gasification.pdf
,
it contains all I found as per last year. If anybody knows of models
that are not included there, please let me know, so that they can be
included in the next update.

Correct me if I am wrong but I am under the impression that Roger
Sampson's Mayon Turbo Stove is designed to do just this kind of job?

Dear Paul
I find you report encouraging. People already see the value of
making a high
energy fuel from a pretty lousy biomass, and it is only a short
step to
using the gas as well for any of a variety of purposes. I am
inclined to
think that a large scale process heat application will give a
better quality
or at least consistent product.
Is there a missing technology: a stove that burns the whole rice
hull
instead of making char? Perhaps as a slightly compressed block or
cylinder
whole rice hull could be made attractive, clean and efficient in
the correct
device.
I do not know whether a stove can efficiently burn rice husk.
But it seems rice husk can be burnt efficiently in FBC ( fluidised
bed combustion ) boilers. There are several medium sized FBC
boilers operated all over India. So the fuel need not go waste.
Regards,
Rajan
