I decided that my 400 gallon supply of WMO from the shop is just worth waayyy to much to give away... So I'm gonna build a centrifuge setup to clean it and burn it in my 12v, my Mercedes, and maybe the 6.5 Chevy. oh, and the 12v cummins tractor.
Originally, I was going to build a setup to burn it for heating the house/shop by putting a waste oil nozzle into the wood burner. BUT, being that I only pay about $28/cord for wood, that makes the waste oil only worth about $0.23/gal. Not worth spending $200-300 building a burner to burn $92 worth of oil. BUT, at $4+/gal for diesel fuel, that same amount of oil is worth over $1600! So, here it goes.
I have a 40 gallon electric hot water heater. Plan is to torch open the top. The bottom element will remain, and be used to heat the oil in the summertime when I want to filter. I will install a copper coil in the tank that's attached to my wood boiler with a pump, so in the winter time, I can heat the oil for cheap off the wood burner. For a pump, I have an old worn out 16gpm Hydraulic pump off a ford tractor. Pump would only make 400psi on hot oil, hence it's needed replacement. But for me, 85psi is all I need, so perfect! And it's free. Got a 60gph centrifuge off eBay for $124. Have most the odds and ends plumbing already laying around. (When you build your own home-brew computerized wood boiler heat system that cost $7k in plumbing alone, you end up with lots of misc stuff hanging around!) I might use the extra processing power in the wood boiler system's computer (have some unused inputs and outputs that I can use to run pumps, etc) to control cycle times, oil temperature, etc.. Or make it stand alone..... I've got an old air compressor motor that I'll drive the pump with. And, I'm thinking on getting some really strong magnets to stick to the bottom of the tank to catch metals. The drain of the centrifuge will be setup so I can tap off it to fill oil jugs, so when I'm done filtering, I'll fill my jugs with the discharge of the centrifuge to make sure of no possible contamination from scum in the waste tank.
Hope to get pics up as the project progresses.. Any of you that have done this already, I'd love to hear your tips/suggestions.
