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.
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.
- 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
