I've also been thinking about this. You can definitely burn wvo, or almost anything else, with a waste oil burner. A few companies make them; econoheat.com has a nice website. The great advantage of this is that you can burn your wvo, and if it is not available, you can buy heating oil. The disadvantage is that you have to replaceyour perfectly good oil burner with a new $4,000 unit.

The waste oil burners heat the oil and also use compresssed air to help atomize it. I suspect that if you are using clean wvo, and you preheat it like in your car, it would burn just fine. After all, most modern cars are a lot more precise than an oil burner. So I thought I might try running the oil through a two gallon electric water heater to get it hot, then into the furnace.

There might be a problem with rubber seals, just like on an older diesel car.

Other thoughts were to make biodiesel, which I assume would work fine. Or try mixing wvo/heating oil, maybe 50/50 or 25/75.

Anybody braver than me who has already tried this? Any other thoughts.

this makes the furnace work like a torpeedoo heater..

I do indeed, (and I spelled Delavan incorrectly)

If you get one of these nozzles, you need the adaptor. I paid a total of $135 CDN including tax for one nozzle and the adaptor a couple of weeks ago. I chose the #####-7 model and get over 1 GPH flow. My tank is mounted higher than my burner so I don't rely on siphining to draw in my fuel. In fact, my fuel lines are slightly pressurized by the weight of the oil.

I have 2 electric solenoids ($25 each), one to open the oil supply, one for the air line. Once the water in my water reaches 160'F, a thermostat (robbed from an old electric hot water tank) shuts everything down until the next call for heat.

I run the water underground through Kitec pipe (Google that one) in an insulated box to a heat exchanger in my house.

The burner itself is a typical oil furnace burner slighly modified to accept the siphoning nozzle.

The outdoor furnace itself was designed for wood, but I converted it to accept the burner by simply torching a 5 inch hole below the filling door. The water capacity is 500 gallons (way too big) and looks like an outhouse with a chimney. We call it the shithouse furnace.

nozzle and adaptor are required. As for the compressed air, I have an old compressor in my garage. I have an airhose running out the back to the furnace. My compressor is set at 90 psi, but I have an adjustable pressure regulator mounted on the stove to cut the pressure to anywhere from 3 -15 psi. At 3 psi, my flame becomes orange and smoky with lots of soot build up. At 15 psi, the flame roars like a jet (brings a wee tear to my eye).

i have a waste oil furnace that im gonna scrap. if anyone wants the pump and stuff they can have it. the fire box was cracked so i decided not to give the whole furnace away, i dont want anyone going to sleep and waking up dead.

email me if you want it. its located in the 12057 area code. i wont ship it just local pickup.

No, I don't even own a digital camera yet. If you are seriously interested, I'll send you schematics, drawings and photos.

I wouldn't recommend burning preheated oil in a regular furnace as you said you have. I've experimented with it for a while and ignition is highly unpredictable. As well, any residual unburned oil in the combustion chamber could suddenly ignite causing a serious overheating of your heat exchanger, causing warping, cracking or burn through. Ultimately you run the risk of carbon monoxide poisoning and death.

and this fires up every time from the old fuel oil boilers control? the reason i ask is a plumber friend just gave me a working Gas boiler. with all parts and working. i was going to turn it into a drip stove/boiler. but if i install this set up with a ignighter this will work 100000000 better and safer..

i know what your saying about drip stoves . but i built a really nice one acuople of years ago. i add a fan blower to it and there was no smoke. but your correct no controls . you have to watch it all the time. so then i started working with old oil fire boilers to heat my swimming pole with veggie. I can't find my pic or post of my drip stove but it was close to this one ..

mr booly
so you don't use the fuel pump on the gun? just the fan (air) or not even that? what do you think should i turn this into a WVO boiler? this is the working gas guts from the gas boiler..

Mr. Booly,

THAT is what I've been looking for. Compressed air injection nozzles...

Thank you!

I think we'd all appreciate if you'd follow up with some pics, additional links, etc. This has been an area of interest and frustration for a long time.....

Mr. Booly, please email to me any any drawings, notes, etc. I'm very interested. I have a couple of hot water pressure washer burners/coils that I want to modify or I'd prefer building from scratch.

I don't weld but have friends who are pretty good fabricators. Please forward any info, particularly on your thermostatically controlled solenoids, etc. You have it to where it will shut down when hot enough... but will it reignite once the temp drops?

Thanks Forrest,

I have one small torpedo heater but will have to check to see if it is a wick type or otherwise. I hadn't thought about putting the whole thing on a hotplate. Boy, I can see how it would need constant monitoring.

Somehow, I still see a heated fuel tank system... preferably in a pressure washer burner/coil assy.

Hi mr booly, good info! Please email me (see my profile) any info you may want to share. How about a Weil McClaim steam boiler? Is it feasible to run it remotely with steam using a wvo burner?

Don if he heats it or adds gas to it it works better...

There is a lot of info quite specific to all this on the yahoo discussion group "altfuelfurnace".

And MT, if you are hesitant, you probably should not make this conversion. Almost everyone has problems at times; the least of them would be a cold house and it could be much worse. Wait a season or so till all the bugs are worked out.
Some are having success running 10 to 30 % WVO in their heating oil tanks, but this sometimes leads to burner failure too.

Under no circumstances would I recommend burning high viscosity oil in a regular oil furnace. While my furnace does not smoke, I do produce large amounts of soot inside my combustion chamber. As well, my furnace is located outdoors 50 feet behind the garage. All of this is highly experimental so far. I do not have to concern myself with CO poisoning, residual fires after the call for heat is satisfied, or equipment damage. If your furnace is in your home, I can't stress enough the risk you place yourself and your family in by burning anything other than no.2 fuel oil in that furnace.

I preheat my oil only to keep it from gelling when it gets cold. As well, I keep a little heat on my filter via a 40 watt light bulb just to ensure the filter doesn't gel up. But because I'm atomizing the oil so fine with compressed air, I get dead reliable ignition every time with an oil temp of below 60'F by the time it hits the nozzle. Viscosity is not a serious concern with my setup. I've been running my furnace since late Sept without any problems, unless you call changing a $4.00 filter once every 2 weeks a problem.

You're on your own preheating oil through a regular furnace. The risk far outweighs the benefit in my opinion.

gargoil:

Do you preheat? and to what temperature? I too burn straight WVO but only preheat to about 45-50'F. Just enough to keep it from plugging my filter.
