Hardwood Bricks

Has anyone tried burning hardwood bricks in their RMH? I would think these would work well due to their uniform shape and slow burn time.

Chuck Hazzard : I had to Google this, as Hardwood bio-brick has not yet entered our market! I 'wood' like to see a detailed break-down of what besides hardwood
sawdust and by what % they were used. I think it could come down to price, but I would want to know that I was buying Fresh Bricks as if this stuff over wintered,
I would expect the % of water content to climb A Lot ! this would affect what is their great selling point, their Hotness.

I used 10 minutes of my life to read the reviews and find I am shocked all over again by just how ignorant and simple some people with wood stoves are !

If you live within or close to the place where they are manufactured, and can 'get a deal' I am still worry about the reported expansion of these Bricks as they
expand ! you could end up with more wood exposed than oxygen supply, with a Rocket Mass Heater already at maximum temperature -combustion chamber
glowing cherry red If the Air supply was diminished by the 'Bio-Bricks' expansion you certainly would get smoke back and How the #%^*@@$%% would you
ever fish the sawdust back out of there?!!

So- Try it in a regular wood stove,? Maybe. Try it in a RMH, maybe one 'brick' at a time not the way the manufacturer wants you to use them, there are also
some reports of damage to the catalytic Converters on high end wood stoves ?!? and voided warrantees too ! for the Craft Big AL !

Hello Al,

These bricks have very low water content it any, but the expansion would likely be a problem as you pointed out. I have a good source for these products at a low price, but.......

Thanks for your input.

There are different shaped ones on the market. Most are the giant Pez rectangular brick, but there are different shaped bricks and some long round ones available as well--about 1.5" diameter and a foot long.

I think the round ones would run perfectly well in a normal rocket stove as-is. I think you could make a feedtube work with the blocks, but I don't think it would be considerably bigger than a regular feed tube--think two metal feed tubes that drop them into the burn tunnel with the air coming down in-between. You can't burn one stick, ya know.

I looked at getting either one of those machines or a pellet mill, as I have access to nearly unlimited hardwood sawdust. They are ridiculously expensive.

They claim about twice the energy density as cordwood, I thought of buying some to stash as part of a blizzard kit (easy to store half a cord in the house) but never did.

I have a contact with one of the mfg in Canada so will ask about making round sticks. I otherwise have lots of blow downs in the woods behind my house, so free energy other than the work out to cut it up, carry, and stack.
