 Homemade Diesel 3
Upgraded the small processor to something larger. Like my last processor this is a batch processor. Wanted to experiment with better insulation and heaters. Ran tests on contaminated diesel and nasty oil. Learned a lot. While this design is better than my tiny processor in Homemade Diesel 2 it still needs some work on the design.
I started my project with a length of old steam pipe off the scrap pile. I had to make an idler roller for the weld positioner. Kinda got carried way. Next because the flange on the old pipe was 6.5 Welded the end cap on the what will be the bottom of the processor and test fit one of the ceramic band heaters.

Next because the flange on the old pipe was 6.5" in diameter instead of the modern 7.5" I had to cut out a flange cap from some scrap plate. Welded the end cap on the what will be the bottom of the processor and test fit one of the ceramic band heaters.
I found that I could have 2 After installing all the insulation it was time for the heaters. I installed two near the bottom. The long factory bolts were replaced with shorter bolts. A ratchet strap was used to hold the heaters in place while swapping bolts. The last section of stove pipe and insulation was installed with an opening to access the heater electrical connections.
I found that I could have 2" of ceramic insulation using 7" metal stove pipe as the external skin. I rolled the insulation around a PVC pipe form and then installed the stove pipe prior to sliding it on the metal pipe. After installing all the insulation it was time for the heaters. I installed two near the bottom. The long factory bolts were replaced with shorter bolts. A ratchet strap was used to hold the heaters in place while swapping bolts. The last section of stove pipe and insulation was installed with an opening to access the heater electrical connections.
The flange gasket had to be trimmed slightly due to the older style flange. This seal proved effect even at the high temperature. The material was rated for 850F degrees. This shows the electrical hookup. Top exit with insulation. The thermal couple and exit pipe is from the old processor.

The controller was fitted with a double pole relay to it would control the two band heaters. Each heater is 850W at 240V for a total of 1700 watts. Measuring amperage draw during operation was always around 7.1 amps so it was dead on. This is the complete processor. You can see how tall it is. This is the oil and diesel mix before processing.

This is after processing. At the end of the processing the upper temperature will begin to fall and the lower temperature will rise. Here you can see just how hot the band heaters can get. After the processor cooled I was able to dump out the carbon that remained at the bottom of the processor. It was total baked dry. No liquid remained.
