run a converted oil burner gun 

Care to elaborate on this? What is a converted oil burner gun?

the unburnt  gases becomes pretty flammable and if you don't choke it off 100% and let it cool down it can reignite and blow the door right out of your hand if it does .

I didn't realize that waste motor oil gases were that explosive. I assume you are still referring to a drip system.

What about an idea to just spray oil into the firebox when calling for heat, and limit that to, say, 1/2 a gallon and then shut the oil pump off?

I see that waste motor oil has about 140,000 btu/gallon. Now, is that only if sprayed in a fine mist? Or, can I expect those kind of btus by just spraying the oil onto the burning wood?

I'm still trying to understand this whole thing.

Waste Motor Oil / Outdoor wood boiler conversion
« on: March 17, 2018, 07:26:41 am »
OK, I just found this forum yesterday. I’ve done a little searching and looking but cannot find exactly what I am wanting to do.

So here are my thoughts.  I have an outdoor wood boiler that I have been heating my house with this winter using just strictly wood.  But I got this idea of possibly using waste oil to help cut back on how much wood I use.

 I was thinking of just taking a 55 gallon drum of motor oil and pumping it directly into the firebox whenever the boiler calls for heat. My original thought was just to simply have a metering system so that it would simply spray about a half a gallon of oil onto the wood in order to help get the fire burning quicker.  But after talking to some friends I thought there may be a way that I could actually convert the wood boiler into a waste oil/wood boiler.

 I was thinking kind of a hybrid system where I would continue to burn wood and  simply spray oil into the firebox when it was calling for heat. But I’m not sure if that would even work. Or how it would work.

 I figure I can get about 500 gallons a year of use motor oil from my employer. They also have Synthetic hydraulic oil, but my boss doesn’t think that would work for a waste oil burner.

 So I guess I have two questions right now.

 First of all, would synthetic hydraulic oil work for a waste oil burner?

And also, does anyone have any suggestions on how to use my outdoor wood boiler to also burn waste oil?

I’m sure there is a way to convert the outdoor wood boiler to burn only waste oil. But at this point I’m not interested in doing that. Simply because I don’t know if I could get enough waste oil to heat my house. But also because I think that would probably cost more money than I’m willing to put out right now.
