Timberline / resolute acclaim refractory question ?

That chamber is almost exactly the same as the original. All the slats are spaced the same and bent to mimick the originals .
I took the old one apart and copied it.
That's what they look like inside and that is 3/8ths boiler steel ... It isn't going to warp . It's designed for extreme temps.

I know that s what they look like i work on many of them. And you may be right it might not warp but in a boiler aren't both ends supported? and isn't the steel usually covered with some shielding? I don't know boilers or incinerators very well so i am not sure. What alloy is the steel you used?

The alloy is industrial incinerator stainless steel. Don't know the #
But it is extremely expensive and not practical for what I did with it.
if I was to purchase that steel I could of probably bought a new stove for the same price .
The steel is lined in a couple areas but not lined where the heat transfer are is. The lining is used mainly to reflect the heat back and concentrate it on the super tubes .
The cover that will be welded to the top of the chamber will help stiffen it up even more. I was just showing the guts so others that are following could see what it looks like inside before I weld it up.
And on the out side there will be the fire bricks but I'm also changing that to the tiles .
If it does some how warp I don't have anything but time invested in it. Cutting that steel takes a long time . It isn't easy .

Well i don't really see a safety issue with it as long as you keep an eye on things. I would keep an eye on the condition of the stack to see if you are getting good combustion. I still would be surprised if it didnt warp but i hope it works out. I hate working on those boxes they are so delicate it is a real pain. I personally wouldn't do it due to liability issues but as a pro i have to look at things differently.

My only
Concern is too much heat going
Up the stack . I know the stainless will hold a lot of heat and make good combustion but will it hold too much ??? That's my concern ..

I would be a little concerned with the material surrounding that chamber overheating. It was designed to stand up to the heat on the outside of the insulated box not a steel box. i would keep an eye on those areas for signs of overheating.

thought of that too . Was going to make it a little thinner to put the Kaowool behind it but one of the contractors said he didn't think it would effect the cast iron because the heat won't be directly touching the cast and the steel will not heat to the point of damaging the cast.
I guess I will find out .

I am really looking forward to seeing your results. Nice work on the duplication.

There are already wood stoves using stainless baffles not sure how this application differs but time will tell how this holds up. As he mentioned in a post above that this same stainless is used in incinerators that reach much higher temps. I imagine at his job there are lots of people with lots of experience with high temp incinerators to seek out advice.

Dismisser,
Alot of times you dont get alot of support on this forum on making a change to the orignal materials or design as they take the position that the average joe will end up burning their house down making mods or fixing a wood stove. So dont take it personal. Its just safety first as they dont want to promote a bunch of stove modding. As you never know who is on here looking at posts and for information.

Very true never thought of it that way ...
There is a lot of ppl out there that lack common sense.
