What I have experienced as a helpful tip for those not using the oil for fuel in the compressed and internally combusted mode… I have waste coolant that is a water and oil emulsion that has lost its ability to function well as fluid in my machines, but when added to the waste oil that has water separating out at the bottom, it will help lower the viscosity of heavy oils and keep them together when mixed well, for long enough to atomize in the burner.
The cost, as they say, is that now the heat that the fuel being consumed is releasing, is being used by the water to create steam not heat. There have been days when the oil to water ratio has made the burner run non-stop and scarcely provide the needed heat for my building. However, It has made possible the use of fuel that was rejected by other consumers. I’ve tried burning the bad stuff without the coolant and the pump cycles only the water, never even catches any oil. Not sure what will happen to water in the turks but that will be tried soon too… I made one on the small side… out of the two different small (32oz or so ) propane tanks. quick clean and fun!
This is a very useful tip. In Europe they now use a bitumen slurry containing about 30% water in large diesel engined power stations. Large bitumen deposits are in South America and are equal to the world reserves of crude oil. The fuel product sells for a price similar to coal. Commercial applications are power stations and shipping. Looks like the back yard operator can come up with some DIY applications. Water plus an emulsifier of some sort is needed.
Soluble oil (as mentioned) appears to work. Degreasing products would also be suitable. SC Gunk is one I used to make soluble steam oil long ago and may still be sold in the USA. Better stock up on your alternative fuels. I heard today that Iraq has wired a large number of their oil wells with explosives that will be triggered if the balloon goes up. So don’t expect cheap Iraq oil to be coming your way for a very long time.
