    Anyone ever try to burning filtered wmo in a oil stove that uses a carburetor fuel flow control? Like these

    Thinking centrifuged and small tank next to the stove so it stays warm. Possibly thinned with kerosene. Or two tanks and start/stop on diesel/kerosene then run on wmo. They all seem to have a piece of metal that is some kind of catalyser that helps burn the diesel. They seem to burn pretty clean on clean fuel on youtube. I think it would work but burn dirty maybe and the carb might have some fine sludge settle out and require more cleaning. Over all I think it would take more cleaning. Would be quiet and simple.

    Saw that one guy on youtube uses homemade biodiesel for fuel in his stove. Obviously wmo and wmo are not the same.

    We burn all of our used oil in a lanair oil furnace. We can burn anything from fuel oil, atf, wvo, and wmo. It has a pair of cartridge heaters that it uses to heat motor oil up to burn, that you would shut off to burn fuel oil, this heat helps to thin and atomize the wmo for the combustion process.

    That catalyser looks to be nothing more then a piece of metal they heat cherry red to help have a clean combustion.

    I don't see an issue with burning wmo in place of fuel oil, so long as you heat the wmo up before injecting it to burn. You'll also have to clean it out periodically because burning wmo typically creates a lot of ash. You might have to get different nozzles for the injector and a good filtration setup so as to not ruin the pump.

    Yah I have wanted to rig up a home oil furnace to burn the stuff for years. I have seen some cool mods for them. It's the way to go. Syphon nozzle, heater block, etc. Burns really clean too. But I kinda looking for a quiet and none electric. Maybe even a fireplace ambiance.

    I think it would be all okay too. Yah looks just like a piece of metal. Wonder if it would get sooted up or stay clean. I would run everything through my centrifuge so it should be pretty clean. Definitely agree about heating wmo would help. These stoves don't have a nozzle, but a tube that can get coked up. There looks like it has a decoking rod to clean that out. I think it would required some extra cleaning from the dirty fuel.

    Hi in the Cascades, Nearly- Redmond,Oregon
    I already have a working used heater ( have to go look what brand) burns WMO, Kerosene, Diesel, whatever that I'm going to install soon as I get my shop built.
    Supposed to be all set-up to burn all the above.

    Well chatted with a guy that tried a few things. He had some good information. He said, viscosity is the big thing for the regulator. I don't know how well he filtered it. But getting solids out is important. He tried wmo with heat, new veg oil, and blended veg/kerosene. Results were wmo coked up so bad in an hour that the fuel would not flow to the correct place in the pot. Which means it wasn't getting under the vaporizer and getting a good burn. Had to many solids, guessing carbon, from diesel engine wmo. Veg oil had to be filtered and had problems with viscosity and solids too. He said the different fuels wouldn't hurt anything in the stove. I asked about really heating the oil and going thought the fuel regulator. He said hot oil should not effect it as long as it is not extreme. Did think that some of the rubber in the regulator could bulge/swell if too hot. This could cause it to malfunction a overfuel or overflow. He hear that running biodiesel required cleaning about every 9 days of operation. So that was not bad. He debated the effort to make the biodiesel just to burn in the stove vs how cheap the fuel is currently.

    I didn't ask about blending gas/wmo. I wonder about blending some gas in to bring the viscosity down and some flame to the oil.
    Might be interesting to try out.

    **There is a risk of the gas to offgas in the stove post shutdown, warm, and making a hazard when starting. Might have to suck out the combustion chamber prior to lighting. Maybe not, not sure. It could stay blended just fine.**

    Scored this heater off Craigslist for kinda cheap. Needs some glass and plumbing to get it functional but will try some wmo and blends to see how it does.

    I burn wmo in wood stove. Very simple gravity feed system with a ball valve to regulate flow. It drips oil onto the wood, so it really a combination wood / wmo burner. Works great!

    oh cool I have seen that on youtube and looks like it would work well. good info thanks. Bet it burns pretty clean once the fire is good and hot. When do you normally start adding oil?

    Typically wait till the fire is burning well before starting oil. The biggest surprise you'll notice, you actually burn less wood!
