Composition of brick

[dravick10]

Hello all,

I'm a new member and wanna build a rocket stove mass heater. I decided to use dense brick for the combustion chamber, so I recently contact a refractory material business, and they propose to me 2 kind of brick rated for 2800 F.

- one brick with 70% alumine 9'' x 4.5'' x 2.5'' --> 7 $ each
- Jet DP brick, 9''x4.5''x2.5'' 2850 fahrenheit --> 4$ each data sheet (56.3% Silica, 37.6% alumine)

Both brick have an high density.

Did you think the Jet DP brick should work ?

Thanks

Welcome dravick10,
Its nice to see you have been searching for materials already. Do plan on building a J style or Batch box heater? If both dense bricks are rated same temp capacity, you should be fine with the less expensive one. But, more info is needed about what you want to do. There are also homemade refractory mixes posted here you may wish to read up on...

Hello, thanks for the reply.

Im a total newbish concerning making stove etc. I need a stove for a Yurt of 32 feet of diameter, its like 800 square feet and 14 feet at the top, with poor isolation (like r8) 2 canevas + aluminium doubled foil. For now, first plan was to build a 8 inch J-type, but I read the info about the Batch box too and not sure about what to build, J type can be fun to 'feed' the dragon, but more work for splitting wood and such and I reat that the Bactch box is more efficent. I need a mass to keep the heat, to put a bed and/or a bench on it etc. I bougth the dvd of Erica/Ernie for the rocket stove and create a Sketchup drawing for a 8 inch system.

Some guys tell me to check for the half-barrel bell to put maybe under my bench, I just start to read about the bell system and still figure to trying out how to calculate the drag with the barrel bell things .
