I got an idea I want to run by you all, it might have been tried before but I haven't seen it, or it has never been tried (for good reason?)
what if I used a liner for securing old chimneys as a furnace? In Norway it is used for slipping inside an old brick chimney as a fire precaution. The liner is made of some sort of concrete/ceramic and is rated for 800 C.
I thought of insulating it with Rockwool on the outside. Maybe some sheetmetal to enclose the insulation.
If it worked I could easily get a replacement inner chamber when the old one is gone.. I got a length of liner ready.. :
What do you think? Anyone tried it before?
