Gassification Chamber Refractory

The refractory "bricks" that came with my Eko 40 three years ago have finally cracked in half and should be replaced. I see I can purchase new ones for around $100. I was wondering if anyone had any experience or success making their own out of firebrick or refractory cement. Thoughts?

Is the steel exposed by the cracked bricks? If not you can probably just keep running it. Not sure what the inside of the EKO looks like, Randy

I have started making refractory component for our Jetstream. It is most important to follow the instructions to the letter, and the curing process is critical.
I do not know just how many "bricks" your Eko 40 uses ? But it does not take long to use up $100 of refractory.

If you decide to make your refractory bricks, get some refractory needles. Even if your bricks crack, they won't fall apart as fast. This is the link to the website where I got my stainless steel refractory needles. They were also helpful with advice.

My feeling is that firebrick that is put together in such a way as to mimic the original cast design will have some stress
relief built in. Just make sure you get something that is rated for as high a temperature as possible.

Mine has had cracks in them for 3 years now as long as they are not falling apart they work fine.
