Seems the super oxygen in rocket stove combustion would burn rubber hot and clean enough to be a viable fuel.  It is burned for the manufacture of portland cement.  Any experiences with this?

Hi Walter, and welcome to permies! I think that a properly-designed and well-tended RMH would be able to burn rubber without incident. I've fed a few bits into mine when it was going and ran outside to see if I could detect any burnt rubber aroma around the stack. Nothing but steam came out as far as my nose could tell. So there's one anecdote for you....

Without a gas analyser we can't say for certain what sort of combustion products are coming out, but my gut instinct says that if you're careful you might be able to burn a mix of rubber and wood, and experiment with the ratio to see what works.

I'm guessing small amounts at a time would be in order.  I've heard accounts from two men way older than me that had the job of getting the morning fire going when they were boys.  Some "helpful" neighbor would tell them them to throw a chunk of an old tire into the stove for some quick heat.  Both tried it and told stories of turning cast iron stoves and the stove pipe bright cherry red and almost burning their house down.  They both laughed about when they told it but said their dads were not amused at the time.

Hi Walter;  Big Welcome to Permies!
As Phil said ,with experimentation you probably could burn rubber.

I doubt you could burn enough cleanly to make it worth while.
Add too much and you would get stinky black smoke,known as fuel overloading.

Adding small bits to perk up a fire might work well, I have been known to splash used motor oil in the feed tube of a J rocket...  Makes them really get going!
Add to much and your polluting the air.

Has anyone done any experimenting on this since?  I am seeing used tire mountains popping up everywhere around here. It's super tough for automotive shops to get rid of them, we need to come up with a solution to tire pollution quick. I've never seen it like this!

There is quite a bit of steel in modern tires as well, which could melt down into a nasty slag to dig out.

Still, looking forward to some actual experiments so we know what these sorts of details amount to in practice.

Cutting up the tires would be the first thing I would look into, I used to own a tire shredder as the strips of rubber are used for crab pot construction but it was a big petrol powered beast and a real handful to operate!
 
I'm tired of walking, and will rest for a minute and grow some wheels. This is the promise of this tiny ad:
