Re: Dynamo/Gen Set

If that is just a typical automobile alternator you indeed will not get much power from that configuration, you need much a higher rpm to get into the range for automobile alternators to start producing current. I note the video showing the engine running on compressed air doesn't show the electrici...

Re: Steam engine from the North Caucasus

The rough estimation of Boiler Horsepower is 10 square feet of heating surface = 1 boiler horsepower. I have a 6 Horsepower Toledo Steam engine on Nyitra coupled with a boiler that has the following specs: 200psi MAWP 72 sq ft of heating surface 362 lbs/hr (ASME calculation) For me this seems to be ...

Re: Steam engine from the North Caucasus

What is important is that your boiler should be a reasonable match with your engine, and your hull should have enough buoyancy and structure to support all of the weight of the steam machinery. Steam equipment is quite heavy. If you look at how many kg of all the equipment per horsepower, it is high...

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...

Re: Steam Pressure Regulating Valves

Fred, The exact one I have ordered is this model McMasterCarr Catalog #: 47345K32 - 40 to 110psi model https://www.mcmaster.com/47345K32/ It is 3/8" npt inlet and outlet. 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...
