[Stoves] Rice Hull Cooking Stove

Tue Oct 10 21:09:40 CDT 2006

Dear Walter,

Welcome to the club!! (Stoves Listserve is a "club" of stove 
enthusiastists who
enjoy interaction with people just like you.)

Your chosen topic is rice husks (or hulls) and the stoves that can use 
them.  As
Andrew correctly pointed out, the Mayon rice husk stove has been 
brought to our
attention by Roger Samson.  I would like to add that Roger was working with
Alexis Belonio of the Philippines.  Roger has many talents and 
interests. Alexis does also, but Alexis should be called "Mr. Rice 
Husk".  Rice husk
characteristics and uses are his focus, focus, focus.

Alexis is a subscriber to the Stoves Listserv, but I have added his address to
the recipients list so that you will have it, and we will be sure that Alexis
sees this message.  Same for Roger Samson.

I recommend that you go to
http://info.bioenergylists.org/en/contributors#Belonio    and see 
several items,
especially the "Handbook".  In the Preface (which I wrote) you will read why
that work is so important.  Later I met Alexis at a workshop in China about
gasifiers, and am now even further impressed with his work.  Because of 
Alexis,
I have become involved in the study of rice husks as fuels for small 
gasifiers. (Much work on rice husks for large gasifiers was conducted a 
few decades ago.)

Several things about rice husks and on-going work:

1.  Making briquettes from rice husks does NOT seem to be necessary nor
advisable.

2.  Both Alexis and I are developing stoves that will take dry raw rice 
husks as
the fuel.  In the works are: an improved Mayon stove by Alexis; a smaller and
less expensive version (by me) of the batch-fed T-LUD gasifier 
described in the
Handbook; two separate versions (by Alexis and by me) of continuous-feed small
gasifiers; and a possible "small-industry gasifier" for process heat.

3.  Except for the Mayon stove, all of the other rice husk burners mentioned
above utilize forced air, meaning at least the air power of a good computer
fan.  We need the air power to overcome the lack of air passages through the
column of rice husks.

4.  Although both Alexis and I would love to generate some income from the
stoves, we agree that the ideas that are published and others that could be
shared individually should first be pushed forward to become useful 
products in
successful projects that benefit needy people.  For this, we can use your
assistance, and we would like to get to know you and your capabilities (and
limitations).

So, subscribing to the Stoves Listserv is important if you want access to the
full "club".  Otherwise, you now have the addresses of Roger, Alexis, and me.

Many others could have interest in rice husks as stove fuels, but 
interests and
actions are not the same.  If anyone knows of anyone else who is actively
working on this topic, please help us make the connections.
