the kiln is 8m long and anything inside gets coroded, so I made buttresses. Try to find information on masonry butresses. the poles are temporary.

Re: Clamp Kiln Vault And Chimney


My understanding of a clamp was that there was no permanent structure, the brick of the clamp were part of the firing. Here are some pics of a Mexican clamp. Eventually, all of the brick except for the side walls will be cycled though the center of the kiln.

I thought kiln without permanent walls was scove kiln. Even the pics in your link , those are permanent walls.

But what do i know. ;-) and i figure i know less every year.

http://www.britannica.com/technology...rial#ref609111

" The clamp kiln is an improvement over the scove kiln in that the exterior walls are permanent, with openings at the bottom to permit firing of the tunnels. "

You could be right, that was just what they called them. In the last pic, that is an abandoned brickyard and the walls are clearly still standing.

Last year I opened a thread asking advise about this chimney. I was hoping you would say something. Would like your comments on this chimney. what would you need to know. I am wondering about going another 100cm higher.

I am wondering about a cap or not.

If you are looking to increase the draw,Not only would I go higher,I would taper the chimney also. Contrary to logic,reducing the dimension of the flue has a very positive effect,it works exactly like a venturi in a carburetor.

Re: Clamp Kiln Vault And Chimney


Exciting times at the Brick Kiln.

I think i know more about what not to do then I know what to do!

I built the vault under the old existing roof that was rails for rafters and wood for purlins. then TnG then asphalt composite . The asphalt paper never lasts long so it is three layers. In places the purlins touched the outside of vault. In fact it prevented putting the second layer of bricks on the vault in places.

I planned to remove the wood roof after this firing and put something waterproof over the vault.

Lo and behold with the vault closed the heat was incredible (well duh) and started a purlin on fire. The tng and roofing sheets inhibited the fire so mostly the fire followed the purlins, but to put it out we destroyed parts of the roof. Luckily it was noticed and it was put out. so the wood roof only covers half of the vault now.

Now how to make the top of vault water resistant on a brick that can get too hot to touch. Originally i was goin to lay some old 5mm thick plastic (big sheets that are hollow for heating water for swimmng pools), but now i find it could melt.

So I know a bit about what not to do but am not sure the solution. I am leaning towards sand/clay/ lime plaster.
