Waste oil burner-100% Free Heat!!

Building a waste oil heater for my shop

[kzfittycent]

When I was in the USAF, we had a "Clean Burn" oil heater in our shop. Loved that thing. I always wanted to build one of my own for all the used oil I have. Thanks for sharing.

I build a simular burner 30 years ago. Headed a 2, 000 sq ft area real good, but the shop burned down one cold day. I started a fire, I had a 20 gal used oil drum overhead to feed the burner with. The weather was very cold, abould 30 degrees in the shop. I started the fire and then unexpeakly had to leave. The oil was cold went I started it and the valve was turned up enough to started the burning. After I left, the oil warmed up enough to start runing at a flow faster than it was burning. Oil overflowed on to the concrete floor and must have started burning and all hell happen. I now realize I show have build a pan around the bottom of the stove than would have held 20 gal of oil. Out side of that, the stove worked very well.

We used a drip feed diesel stove to keep our tent warm(ish) in Alaska in January 76. It would get the inside of our army issue dual wall tent up to 30 some degrees. It was -50 outside.

In the Army, we had field mess kit barrel cleaners, RAPID boiling water with a drip feed of kerosene. The burner, water tight was lowered into the HEAVY DUTY GALVY barrel of water, a can of fuel having a valve to control kerosene drip was strapped on and combustion was begun with a piece of lighted paper. The tube from the fuel can was about 1/4” dia and there was considerable distance from end of tube to burning ring below water. Consider a small fuel feed as there is less chance of flame working it’s way toward the fuel source. You can probably look these units up online to get the proven design. Good luck. Safety first and foremost. Steve, Plymouth, MA

Not enough air and to much oil in the burner. Drip the oil very slowly, about 1 liter or 2 pints per hour. You need the pin valve to regulate the oil flow. Also extend the chimney flue to speed up the airflow. another suggestion is, separate the flue from the burning pot. get rid of the flange and let the flue which have holes in it to be about 2inches about the rim of the burner pot. This needs little experimenting to achieve best burning without any smoke at all. To start the fire I recommend use little diesel mixed with methyl alcohol to heat the burning chamber. This prevents too much smoke and soot sediment in your flue. this method is very good in the winter when even the diesel is hard to start burning. I used the Gas blowtorch to lit this mixture which is much safer than using petrol/benzine. You need to clean the burning pot quite often as the sump oil is very dirty. When I had the heater I used two cast iron pots - one in one out being cleaned. I hope this will help you to achieve the best result.

Built one in Oklahoma out of a old water heater tank. I had a 18 wheeler so had plenty of used oil. Would heat the shop in the winter. Tank would get cherry red around the bottom half when you turned it up. Not a heater you would want to leave and go to town for parts though. Have to watch the heat and drip !

The incinerator works well, your work was a complete success, good job !!

You should fill the top side of the air compressor tank with sand so it heats up and radiates heat longer like aa thermal battery. Just seal off that plate you welded in and put the pipe through so sand doesn't fall down. Should hold 40 lbs. Also I'd just use 2 brake discs instead of the dog bowl. Plate off the holes on the bottom disc for the studs from the other side and you have a much thicker base. Weld the 2 together with the offset facing outwards.

Good hearing from you again! If you ever need any scrap metal, you can have any or all this that I have down here. I would like to get rid of it.

Hi, how did it work out for you? The reason for smoke is that you need slightly higher temperature inside such that you get secondary combustion. Adding one or two plates horizontal inside would probably do the trick since that would force the flames to spend more time inside the burn chamber. The retained heat in the horizontal plates would cause a secondary combustion resulting in higher yield and no smoke.

All us garage dwellers should have a waste oil burner

[clintcowles]

I have built a stove very similar to this...if you are curious I have a couple videos of it on my channel....and I haven't been able to get it to burn smokeless...but it is hot! Nice work friend.

Either enlarge your secondary air holes or drill more of them. The black smoke is because it is starving for air. you can also reduce the amount of air into the pot which will reduce the flame going into the pipe and clean up the smoke. I had a russian heater which had a sliding door to control the amount of intake air. The pipe had so many holes that it looked more like a fence and it burned very hot and very clean.Also my secondary burn pipe was three times the length of yours. You have way too much primary air with that vented disk which creates too big a flame and your secondary burner can't keep up with it(can't mix enough air with it to create a clean burn).

[syndieubanks]

this is a cool idea and u can also burn used vegetable oil and shortening so ive learned

[walterforsiethe]

Cool that you can make that with just a bit of thought and time with a powerarc welder.

[philplasterer]

You need to add a blower to it and it will burn hotter and cleaner. Great job building it Sir

a friend of mines dad years ago had a small old potbelly stove in the garage with a tank on the wall with old waste oil that gravity fed threw a small brake line that went into a hole he drilled in the stove! he used a type of a petcock valve you turned to control the flow! his son started the stove up and turned valve to much and left the garage and when he came back the stove was glowing red!!! lol

[genocanabicea]

You want a combustion chamber and lots of forced air. You can use a ventury atomizers nozzle close to the heat so the mist vaporizes. Or run the last 3 inches of drip line in or near the fire. That will vaporize the oil.

Bass needle valve works great for regulation oil flow.
