Hi everyone, new here at permies, been reading up on castable burn and risers, ceramic floor tiles are cooked up to 2300 degrees, could they be used as a burn chamber and riser lining

Billy Graham :Welcome to Permies.com, our sister site richsoil.com, and Abig Welcome to the Rocket and Woods Stoves Forums. With over 22,000
fellow members you should be able typo come here 24 / 7 and find someone who wants to talk about what you want to talk about !

Just spitballing here but for a 6'' system with a Burn tunnel 24'' long and a heat riser 48'' tall that is a lot of ceramic floor tile, if you didn't have to cut every piece
a couple of times each, I can't see any reason an entire Combustion zone could not be made of Ceramic Tile. The 1st one should be well insulated until we see what
we are working with For Temps and heat energy transference ! For the Good of the crafts ! BIG AL !

Thermal shock might be an issue, but try it, it could work.

Hi guys, thanks for the replies, I can pick up a few freebie (damaged or chipped) ceramic tiles from one of my outlets, I thought about fire cement/high temp sealant for between the joints, built around a knock-down former. I've yet to build even a small basic RS, but my mind and thoughts are on the run to get started. my main objective is to heat water, I have a cunning plan. Like a lot of people, 99 % of how all this is gonna work this lives in my head, so, I will read more and start some sot of build soon. I could use some bricks that I have laying around, but I have a healthy fear of explosions. Thanks again, Billy Graham.

When I worked in a weld shop we had a submersible arc welder. Its and automatic welder and we were trying to weld seems 100% in one pass. They sell ceramics that would go on other side of seam to be welded. So you had ceramic, 1/16in gap between the two edges of the metal and then welder. Point is there was enough heat, very quickly to melt and weld the metal all the way with only the ceramic backing strip to prevent the welder from blowing through.
I'm looking now into where I could cast ceramics for a burn chamber.
