Re: Flying a (steaming) kite

The Amish don't use electricity, or zippers, automobiles, trucks, etc, and I don't know any who do metal fabrication as a business, although many of this group make horse buggy wheels for sale. The Amish are very complicated. On the East Coast the best traction engine boiler fabrication is Jonas St...

My thinking behind this it might be able to support up to two atomizing nozzles in the future. Right now I have one nozzle and ab...

Steam Pressure Regulating Valves

On a recent outing in June we ran Nyitra on a combination of propane, kerosene, and some wood. The 2.5mm steam atomizer worked ok, but it was finicky. As the boiler pressure changed it would require adjustment. I saw a recent post by RNoe where part of the oil atomizing rig appears to have some kind...

Re: Inspiration for the builder: A list of other vertical boilers

If you are going to mention vertical boilers, don't forget the Manning Vertical FireTube boiler.

Nyitra's ASME Boiler is inspired by the Manning VFT Factory boilers that had a wider diameter in the firebox area at the bottom.

Draft Indicator/Gauge

I put a small fitting on my boiler's bonnet that goes via a long copper pipe to a Magna-Helic Gauge, measuring -1 to 1 inch pressure of H2O. I installed it so the fireman could notice changes in air movement through the boiler. The stack is now 5ft+bonnet which helps the draft naturally. There is ma...

Re: How to chose gear wheels respective to torque?

Re: 2.5mm Oil/Kerosene Nozzles

... fire brick as targets that glow red hot and keep the flame outs from happening. That's a good idea, I will bring some firebrick to try that. Probably most of the time I'm going to run Nyitra with 1 of her 2 propane burners on low next to the oil nozzle. I have a 1/4 ball valve for shut off. I'm...

2.5mm Oil/Kerosene Nozzles

I just wanted folks to know that there are some cheap air atomizing nozzles available on eBay for $20 on eBay. I bought the 2.5mm nozzle, and replaced the interior O-ring with a steam rated Viton O-ring from McMaster Carr. (5 pack for $5) The nozzle is intended for air , but I just wanted to let fol...
