John, sounds like a cool design. Any chance you have a photo of the burner?

Also, where in the firebox was it located? And did the atomizer and subsequent flame point backwards to the backhead? Or just generally up towards the crown sheet??

Thanks much,
Glenn

No photo Glenn, but attached is a crude sketch from a 30 years gone by memory...so grain of salt and all. I have no recollection at all of the feed plumbing, and the boiler had a Vanderbilt firebox so it was weird anyway. The burner sat at the front of the firebox and the outlets pointed horizontally (the plate may have been at a slight downward angle for fuel flow) back towards the firedoor/tender. As you built the fire and the flames got to the firedoor you just added more blower to shape them back along the crown to the tubes - same idea as an arch, just without the arch.

Thanks John, I’ll try to fab up a bench test and report back on what happens! Looks a lot simpler than machining a nozzle.
