Firebrick baffles?

My secondary tube style stove has been converted into a smoke dragon.
(Many reasons for this, and lesson learned to not buy a cheap Chinese stove)
Now I'm on the quest to make this stove as wood efficient as possible.
Wich brings me to this.
Has anyone used firebrick as a baffle?
Is there any stoves that used this setup from the factory?
Pros, and cons?
I used the secondary tubes and basically replaced the ceramic board with firebricks.
I have been running the stove with out the tubes and bricks and have already welded a baffle over the outlet. I think this will allow me to slow the fire down more as well as protect the chinsy stovetop

 

Too much weight for those tubes when they get red hot...

 

Was wondering about that

 

Maybe I'll just put the ceramic board back in

 

I found a thread from last year, this style stove had brick over tube?

 

Its not standard firebrick though, it's the real light insulative type...regular firebrick is too heavy and does not insulate well enough IMO...a regular baffle board will do much better

 

I had a small stove roughly 25 years ago that had a firebrick baffle. Just a row of bricks positioned n/s over the firebox seated in angle iron. I think Trailblazer was the brand.

 

I swapped it back this am, to the ceramic baffle boards

 

Back in the mid 90’s I had a Lopi Answer and also an Energy King wood stove, both had fire brick baffles. I’ve also seen lots of old Fisher baffle mods using fire brick but yeah you would need a pretty stout frame to hold that weight up there.

 

Lopi used bricks until somewhat recently. Or maybe they still do in some models?

 

I used this in the fisher for years. Different thicknesses and dimensions to get close to what you need. Easy to cut with a razor knife and strait edge. Last a long time, especially up on top of the tubes like that.
