Modified wood stove to burn used oil:

[MotorSeven]

Definately not legal to burn waste oil in a woodstove, check your state laws.
Not that it matters. Whatever you do DON'T tell a fireman or your homeowners insurance. Can you imagine the look on your insurance guy's face when he sees that contraption?

If you're gonna do it right get an old Becket burner and modify it to work through the side of your stove, would be much safer. Properly burned waste oil burns yellow not blue, needs lots of air and pressurized, pre-heated oil.

Fred, waste oil is no different than gasoline once it gets to rolling, LOTS of energy.

Not that it matters in a steel all steel shop, but it looks like I meet all the requirements for TN:

(d) On-site Burning in Space Heaters [40 CFR 279.23]

Generators may burn used oil in used oil-fired space heaters provided that:

1. The heater burns only used oil that the owner or operator generates or used oil
received from household do-it-yourself used oil generators;

2. The heater is designed to have a maximum capacity of not more than 0.5 million
Btu per hour; and

3. The combustion gases from the heater are vented to the ambient air.

Is there still room for me in TN, we have more rules than that for a dog house.

Friends of ours heat their service shop with a waste oil furnace. That whole place is warmer (by far) then my house! Their was talk of the gubberment shutting them down, but it hasn't happened yet.

I'm thinking, ideally, you would want some kind of a purpose built used oil heater. But then most of us don't have enough used oil to justify that.

In general, used oil is nasty stuff to play with.

Doesn't the cost of filters if you are going to spray the oil, start to get expensive?

I would love to heat my hot tub with waste oil!

Can one burn filtered waste oil in a conventional oil fired boiler?

enerators may burn used oil in used oil-fired space heaters

That would be an appliance designed to burn waste oil. You'll never get caught anyway. But seriously be safe whatever you do!
I've burned waste oil for 20 years this Winter, I have 3 units and do all the maintenance myself. The first unit I bought was a Clean-bURN CB-1400 and the burner was a converted Beckett #2 oil burner that worked well.

OK I know a guy who took a VW fuel injection pump from an old Diesel Jetta and runs waste oil through that into a woodstove, needless to say it atomizes very well.

You don't have to spray it, a drip works fine, but you do need to force some air to it either by compressor or a squirrel cage type fan.

Now if you used an injection pump(great idea Fred) you would have to filter it.

I fooled around with mine today and decided to ditch the wood and build a burner with air feed......stand-by!

BeezFun, yep, c'mon down. I love this place.....20 years behind the rest of the country and I hope it stays that way. We now have a building permit here, foundation, structural & final.....$200. And a septic permit...$500....that's it!

More ammo for you. The oil is pre-heated to 160f and air pressure is at 14 psi on all 3 burners we have.

Yes an old fuel injection pump hooked to an electric motor and filtered. You could turn up the throttle I mean flame

Good luck, Fred

Can't remember where i saw this and it was sometime ago.

Something like a rounded drawer pull with a small hole drilled in it. The knob was plumbed to air compressor and the oil was dripped on to the knob with the air pushing thru the small hole causing it to atomize the oil. No problems with junk in the oil and seems like it did a good job of burning the oil.

Interesting about the drawer pull. I'm still interested in pursuing the hot tub heating idea. A couple of years ago, I used solar with large loops of black pipe. Worked great when the sun was shining. Less so, towards the end of the season. Then I got a cheap air tight stove and had a couple of SS heat exchangers made. It worked, but was terribly inefficient. Quite disapointing after all that work!

Anyone know how a oil fired boiler transfers the heat of flame to water? Is there a coil? Thanks
Don't mean to hi-jack this thread!

Many years ago when I was a kid the neighbor heated his welding shop with waste oil. He had an old oil burner head mounted through the side of a 55 gal drum. Inside the drum were a couple of fire brick as a fire box. The flue was out the top and through an old steel frame window with a pane removed and some sheet metal as a bushing. Worked great but was a bit noisy when the welders were not running. He would run it for a few hours a day just long enough to warm up the shop.
