Re: Red Clay Brick Oven in the Philippine Islands
It was straight from my own thicknesser air dried to 12%, so it was dry.
No matter how you look at it, it wont work, if it worked there wouldnt be a mountain of rice husks free for the taking.

Re: Red Clay Brick Oven in the Philippine Islands
Was it dry? Sawdust can be wet because the sawmills use sprinklers to wet down lumber so it stays straight. The rice is laid out in the sun on tarps until it is very dry and then goes to the mill. This drying is done by the owner of the rice, the husks are dry when I would get them and feed them into the oven. I have hope it will work out. Did the sawdust steam?Last edited by Lancer; 04-04-2013, 01:58 AM.

I put it to one side of the fire and it just sat there smouldering on the top until you disturbed it, then woof, then back to smouldering again.

Re: Red Clay Brick Oven in the Philippine Islands
Thanks UtahBeehiver!
david s, that's a good idea to boost temps really quickly. :b:
cobblerdave, yes better watch how many stoves you build or you'll have a house full. I'm aware of the burning characteristics of rice husks and am going to get a hot fire going with wood and sustain it with husks. Even if something doesn't burn well if the oven is 800 degrees it might be persuaded to do so, at least that's what I'm counting on.

Gudday
I did a quik goggle on rice husks and came up with a some interesting points
By itself in its natural form it doesn't burn well without a stream of air to keep lite something to do with the shape. There is a stove out there that gasifies it to run a burner. There is a processs to convert to solid logs for burning but this seems to be for large applications rather than domestics.
One thing that that stood out that caught my eye was that it has a high silica content. Makes it great for refractory materials and the ash can be used for high temp insulation but to have that released in the air might be a bit dangerous to your lungs . Like I said a quik goggle search but still warrants more investigation.
Davids I like throwing flour into the flames in a hot oven. It bursts into flame before it hits the burning sticks and adds a bit if theater to pizza parties. Appears this stuffs shaped wrong, a would guess something like throwing leaves on a fire it smothers it at first till it heats up and the oxygen get through.
Anyway it's all supposition I would love to get some to play around with but for now I'll have to goggle more

Re: Red Clay Brick Oven in the Philippine Islands
I recall seeing a video where the cook would occasionally throw a handful of what looked like sawdust into the hot oven. It immediately burst into flame and lasted about 5 secs, just to boost the temp a tad. So long as you don't dump in too much at a time, this works pretty well and will not smother the fire.

There will be a special place in heaven for you by helping the locals and taking in the children. Good luck with your build, will be watching with much interest

Re: Red Clay Brick Oven in the Philippine Islands
Dang Dave, you are a wealth of wisdom. Between you and Brickie this problem will get this figured out yet! The bamboo is a great idea. I can cut it into its natural sections do that each has an open top and closed bottom and pack it full of husks and toss it in, problem solved. Between that and old newspapers I think its resolved.
Regarding compacting down into say pellet stove pellets, rice husks are so dry that they lack any resin which is what I think holds such together.
Its good I discussed this with you guys. I'd never have imagined one could smother a fire in an 800 degree oven. Astonishing!

Gudday again
Brickie right if you just chuck it loose on top it will just choke the fire by-depriving it of oxygen. The rolled up newspaper was to get it to the fire in one solid piece, well not that solid.
That seems to be the sticking point ...the solid bit.
I make blocks of seed for the bird life. Seed ,watered down PVA wood glue (its safe ) into a container with a bit of wire .... Let dry and its done. And they love it.
Not saying wood glue is common but why not something local ,flour and water, it doesn't have to be to strong just enough to hold it. Set in some container perhaps a bit of bamboo.
Taking that solid bit a little further consider just wetting the husk and using some mechanical means to compress it . I don't mean anything to complex like hydrolics levers and man power have been around forever. A simple device like those old aluminum can crushers that use to be around.
A way of making that husk into a solid fuel could be usefull to the community like the coconut husk coal.
Anyway I hope something here is usefull
Regards dave

Re: Red Clay Brick Oven in the Philippine Islands
There is no end to the need in this place. So far, with friends, we've built 2 small houses for poor people who never had opportunity in their lives. We do what we can...its never ending to the last breath, part of life in the third world. I consider that those of us not born in a third world country have won the lottery of birthplace. We were born to opportunity, so many were born to poverty with no hope. Yet there is more joy here than in poor places in the west where there is a social safety net. Civic pride is everywhere. Women sweep the streets every morning with little brooms and dustpans, and most places we would consider shacks have flowers growing from old empty cans or rickety flower boxes. Men are contributing time to build a seawall for the chapel down the road. I even went there for an hour and carried rocks. I'm 55 so an hour was enough... People with next to nothing put a peso in the collection plate on Sunday, I love these people...
I'm glad that you give where you can brickie.Last edited by Lancer; 04-03-2013, 01:22 AM.

I'm sorry it's sounds all a bit complex your rice husk delivery systems . I'm more comfortable with somthing simple. One thing about these ovens that you don't really understand till you see one in operation is the tremendous heat thrown back from those walls when hot. There is no visible smoke when there hot it gets cooked as well so.
So .... Grab a sheet of newspaper roll yourself a log of the rice hulls twist the ends some tape /rubber bands. ( I just re read this I'm willing to bet it will attract a comment.) Delievery system again ,keep it simple ...a soft underhand throw into the middle of the fire in a hot oven. That puppy will burn I promise you.
Now on fuel . I live in sub tropical QLD so a popular plant is a small palm called the " golden cane" . Not so popular after you discover how many fronds they drop a real pain to clean up and dispose off. That's till I built the WFO!
Like most palms there full of oil and burn like a champ! Yes I have tried other types as well supplied by my friendly neighbors who throw then over my side of the fence at the first smell of smoke.
Your a champ for adopting those kids ...good on you! ( sigh ... No grand kids yet.)
It's had a positive effect on already on the "brickie" goodonya brickie
