Hi, this project got started about 22 years ago and "flamed out" due to kids, career, moving, priorities...lots of reasons. Then about a year ago, things started picking up again, and I just found this board. Lots of great ideas! Here's a description of what my build is, and I'm always looking for input before I give it a try for real.
Garrett turbo, unsure of model, but I believe it came from a diesel truck
Combustion chamber is truck exhaust, aluminized steel
Flange, end plate, vertical support are steel that has been CNC machined and drilled
Oil pump is a Chevy internal oil pump, sitting in a paint can, driven by a variable speed drill
Oil will be delivered and returned via metal tubing
End plate has cast iron fittings nickel welded, with the outer one receiving propane, and the inner one feeding a brass fuel rod
The brass fuel rod will eventually have a few (4?) small holes along the side
The ignition system is a 15kv neon transformer that will arc across 2 probes, within the flame holder
The flame holder has a bunch of drilled holes, mounts to the end plate via 4 welded nuts
I'm looking for input on anything that may be an issue. In particular, looking for guidance on fuel rod holes and flame holder holes (qty/ location/sizes).
My next steps are to bench test the ignition and fuel, just the plate. This is to check the fuel ignition pattern. Then I am planning on removing the turbo and seeing if the flame can start and sustain with leaf blower air flow.
