Found a 60 year old Rocket Stove!! Old Oil Burner Build

I looked but found nothing on using old furnace heat exchangers for a rocket stove build.  This looks to me to be a perfect start to a great rocket stove.  It weighs around 80 pounds as is.

I plan to add a batch box to the inlet( where you can see the insulation).  I also will add insulation to the inside of the burn tube.  I may have to cut and re-weld the tube.

The "barrel" is double side, so it will also send heat to the inside.  I may add a fan on top to pull heat better.

What does everyone think about this?

Looks good so far, Adam. I would make whatever changes you seek to make and set it up for a test burn before you go much further, though.

If it's like you think it is, a test burn will confirm what you think is so. If not, well, at least you haven't put money into it.

I find myself thinking in the other direction when planning my RMH, such that I think perhaps only the top of the riser will be metal. I don't like the idea of the main piece of my heating system rusting out due to increased oxidisation.

But let us know. I am sure the RMH experimenters will be on to this soon (I have only participated in one build, which, though comprehensive, was a fairly standard batch-box design, and little about it was experimental).
