Rebuilding the inner brick of my wood boiler?

[eric012]

Hey everyone,

Just bought a house with a wood boiler in the garage, started heating with it 2 weeks ago. I was heating wood.. but wood palette. I knew released heat was higher, but not enough to break the walls. So I saw progressive damages that I think I did in only 2 weeks. The brick cracked on the two sides of the inner walls, is there a way to fix this without having to replace the boiler?

I got a t-101 (titan wood boiler made in Canada) which I'm not able to find any infos on the product on internet. I'm from Montreal in Quebec if someone knows a good place where they could help me.

Here is a picture of what it is looking for now

For some reason the photo would not load for me, try posting a thumb directly to forum..depending on the size of the firebox and the way the wall refractory is attached, you will either remove and replace or veneer over the existing. Rutland has firebrick that is only about 1-1/2" thick , some high heat cement and you can veneer the firebox with new brick...

I can't see pictures either.

If the boiler sat unused for a long time, the refractory & mortar might have taken on moisture - than having real hot fires all of a sudden might have induced some damage. Better in that case to have a couple or few real small ones to get the moisture out first.

Also if that boiler has the pressure relief valve outlet routed into the firebox, that could also make for a very wet firebox if the previous owner ran the pressure up (waterlogged expansion tank?) or the relief valve was leaky. Which wouldn't be good for mortar.

Did the bricks themselves break, or did the mortar/cement deteriorate? Thinking that it has ordinary firebrick in there, so you should be able to get it fix up. Would just have to make sure you get the right stuff.

For laughs I tried this, and it worked:

It doesnt look too bad, maybe some different camera angles.

Yes the relief is routed in the fire zone, I made a small video to show a little bit more how it was looking.

Hope the link work this time.

Sorry for my english, I had to record twice to understand what I was trying to say.

Maybe this time I could put brick a little bit more ticker if I got the space to fit it in there?
Does anyone have an idea where I can get the right materials? Is it something I can buy at home depot?

IMO looking at your bricks they still look like they are in good condition , if they become loose at the cracks and start falling out then it is time to do some thing .
