This instructible has no photos, only drawings. This unit I Built in the late 70's for melting aluminum transmissions, bumpers and such.
The unit was about 4 ft square and 6 ft tall, would accept whole transmissions that that had been drained of oil, and automobile bumpers thru its 36" feed chute. the continuous flow of molten aluminum was poured into 1/2 ton molds.
The burner unit which is the main focus here can be scaled up or down for your particular needs. This size unit when burning uses about 7 gals used oil an hour, at 20,000 btu per lb, that's equivalent to 1.12 million btu an hr. much more than most garages need.
A 1.5" x 12" unit was placed in a barrel stove in a garage, it produced as if the barrel stove was running wide open, and burned thru in 5 mins because there was no fire brick. So be careful and have fire extinguishers handy, if you decide to build a unit like this.

Step 1: Continous flow Smelter

This pic shows the 2 main tubes and how the holes are drilled and assembled with fuel inlet and end caps. Muffler tubing, low carbon steel tubing is fine. Size will depend heat output since size determines how fast the oil can be broken down to lighter fuels.
<p>By any chance could you send the pdf file to my email, I am a avid blacksmith and would like to start smelting my own metal. I have too many scraps!!!</p>
<p>oh and fuel can be just about any oil product from dirty drain oil, tranny fluid, fuel oil, etc., </p>
<p>the sketchup file has lots of info in it, print the project directions, just remember all sizes can be changed for material on hand, only holes may change according to volumn of unit, about 1/2 volumn in annular holes so as to maintain some pressure.</p><p>when starting up air and fuel need to be adjusted for color of flame you need from yellow to blue/clear. water just needs to be turned on slowly, too quick and flame out.</p>
I really appreciate this! I've been looking around trying to find a way to improve my <a href="http://www.climecresidential.com/products.php" rel="nofollow">furnaces in Ottawa</a>, and found this very insightful. Thanks for sharing!
You say &quot;was&quot;. Is this unit no longer available to take pictures of?<br><br>If so, are you planning on rebuilding it? I'd sure love to see a step-by-step if you do!
it was used in the 70's to smelt 2 tons a day, (good prices then) and has been relegated to the scrap yard years ago. Small units were built since then to clean up a few scrap yards, but they were made 'disposable' since the jobs were only a few tons.
<strong>this is a step by step of the burner</strong>, the smelter/furnace itself can vary according to the use and size of burner being built. It was in use in the 70's by myself as different sizes from a 2 1/2&quot; diameter to 8&quot; diameter burner. They can be built even smaller or larger, depending on materials available and end use.<br> &nbsp; Since I'm retired and disabled I'll no longer be building another. But will assist anyone in anyway I can.<br> &nbsp; Some reference material you might be interested in and can google:<br> &nbsp; &nbsp; &nbsp;&nbsp; Destructive decomposition<br> &nbsp; &nbsp; &nbsp;&nbsp; crude and refined oil composition, i.e. what grades and types of oil make up the oils you might be using<br> &nbsp; &nbsp;&nbsp; Carbon chains, i.e. methane, butane, propane, hexane, heptane, octane, pentane, dodecane, etc..<br> &nbsp; available&nbsp; Heat of carbon chains - 20,000btu/lb<br> <br> Have fun and be careful..<br>
