[Stoves] burning rice husk

Thu Oct 13 11:35:57 CDT 2011

Stovers, 

I am receiving a sample (so I am told) of wild rice hulls so I can compare
them to white rice hulls. But I am wondering where and how much wild rice is
grown around the world? Such a great rice I would think it would be in
direct competition to white rice. 

Hulls are now being sent to co-gen plants. I am thinking the char produced
may have a better use. Perhaps in retention pond filters or berms to remove
contaminates etc.

Thanks

Frank

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>
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
