 Topic: Barrel stove
Posted: 9 hours 22 minutes ago at 8:07pm |

Hey guys I’m building a barrel stove. I’m actually using a large pressure tank rather than a barrel but same idea.
It’s going in a corner in my shop. I intend to dry stack concrete blocks on the wall beside it and the wall behind it.
How close do you think I can safely put it to the concrete blocks?
Has anyone ever tried an oil drip system on a wood stove?

I have seen some oil drippers somewhere/sometime past on barrel wood burners so yes you can.

Normal clearance to a non combustable wall is 12 inches i think.. I would stack the blocks an inch or two from the wood wall so it can breath... You can cut the 12 inches down to 6-8 inches if you put a box fan or squirrel cage blower and circ air between the blocks and the stove.

YouTube has a few used oil drip system builds.
Also a few that wrap coils around the vent pipe to heat water.
You might fill the cement block with sand to increase it's thermal retention, and insulate the wall behind it better.

they also make concrete panels that are 30" x 60" and 1/2 inch thick... looks like drywall only concrete... couple pieces of that screwed to the original all would help--- with blocks in front..

I would put bottom row of blocks so holes are horizontal and remaining layers with holes vertical. It will help with convection in the air gap mentioned above.
Use a needle valve for flow control and a ball valve right after it for shut off on the oil drip. Be careful of changing viscosity oil and that you don’t over load the fire. It can have an uncontrolled thermal event!

Hey Good Buddy,,,,hope all is going well for you,,,,  Several years ago,,I started to build such an animal and after talking to a friend that had an automatic transmission shop and had built one to burn the transmission oil he saved. His biggest complaint was smoking up his shop on startup. He said he was going to try something like an injecttion pump off a tractor that would atomize the oil at higher pressure for cleaner burning. His home made heater would leak at several places on both barrels and did not draft worth a flip,,,,!!!! It goes without saying,,every seam in the barrels should be leak proof to where you can snuff out the flame by closing the air intake when there is a run a way in the firebox,,,, Good Luck,,,!!! and don't be a stranger,,,,,

I think I will put hardiboard on that sidewall before the blocks. The back wall is just purlins on a pole barn. I may add hardiboard to that as well.

I really like the idea of the bottom row stacked horizontal. Would let a lot of air flow.

Joe I’ll keep those thoughts in mind. I ordered a “supposedly airtight” barrel stove door. This will be a wood burner with possibly oil drip added to it. I don’t think the drip oil burners work well with modern oil.
