Anyone here ever build one?
Been looking at many different in what they use, but same concept( at least in the type I'd want to use. Not interested in the old furnace type. I'm talking the gravity fed dripulator type. I know back in the day a lot of shops used one that dripped down on a wood fire, not what I want to do. I want one that is 100% just waste oil. What I have seen, you have to have a good air source. Most of them ran the copper feed line through a black pipe. the black pipe is the sir feeder, Several built a bowl where the il feeds into, with an air Defuser, in the center, feeding the "burn pot" so that's where the flame gets it's intensity of the fuel/air mix. I've seen anything from a stainless steal kitchen bowl, to a heavier steel made one. I like the home made one a little better, using 4" pipe in the middle of the burn pot with a brake rotor sitting on top to spread the flame out more so it's not shooting straight up to the top of the stove. \
With this type set up dialed in, it wasn't putting out any smoke at all.
One thing I am not sure what or how to source is the blower. Doesn't have to be a lot of pressure, just a decent volume. Any ideas of a blower that I could readily get should it goes bad? One guy was using a 110vac mattress pump. The others, I'm not sure of.
So any tips and tricks from anyone who has built one?
Thinking of doing this because my shop is un-insulated and I go through a lot of wood since I have to run it full blast when it's pretty cold.
I will be using my current wood stove to do this.

Sounds like a Oil furnace back woods engineered. Find an old oil burner from a house and experiment with nozzle mods is where I would start. The pressure is just to get it atomized for better combustion. But from what you said it sounds like a pressurized tank would work with a ball valve or sorts and a home made nozzle to feed a combustion chamber. Why wouldn't a regulated air source off a small compressor work? Kick it on and off like a pressure switch on a well bladder tank.


edit: er shoot try well bladder tank it regulated house hold pressure. I doubt it would make a great fine mist but it would be much better then a dribble. How much pressure does an oil furnace make?
 
you got me going here is the first answer....

Air supply:
Required air volume is about ¾ CFM per gallon of oil being burned. Required air pressure is from 10 to 35 PSI depending on nozzle size and BTU output.

Now I wanna play with all the old furnace pieces my father in law has laying around. Needs a good screen and filter in that order though. All the old recycled oil unit I was around where plagued by dirty oil and even carbon from combustion in the engine. Over time it sludges everything up.
 

Real good video of a house heating oil furnace and pressure vs. nozzle. Its running 100-150 psi...

Interesting, makes me wanna put a gauges on mine.
 
Drew, I have the wood stove, fits nicely where it is. right now, It's a no brainer to just get air and fuel to it. Very simple, just put the parts together, and done. I was first thinking of an old oil burner furnace, but this is so much more simple. Just put the pieces together.
Just looking on Ebay, and a fan that would suit my needs is about $60-$70 bucks
Then I need a few black pipe fittings and maybe 5-6' of pipe, and 10-15 feet of copper tubing
A couple ball type valves, and an oil container., which could be about anything. One guy made one from an old air tank he modified with a fill neck, and ent, then he welded some barbed fittings on the side, one at the top and one at the bottom, connected the two with a clear hove and wah-lah, a fuel level gauge! You can go as detailed or as simple as you want it to be.
 
I get that for sure and I figured that was the intended purpose....so by blower did you mean for forced air in the combustion area or to get some pressure behind the oil supply?
I guess I lost the translation.

the air goes directly into the burn pot, to fuel the flame. kinda like using a leaf blower on an outside brush pile you are trying to burn up.
