What temperature did the boiler run at?
A Stanley Steamer boiler generates nominally 550 to 600 PSIG of steam pressure. Saturated steam at that pressure range is between 475 and 486 degrees Fahrenheit. I noticed from your boiler section that you talk about modern replacement boilers and show a picture of one being made. Are some people that are making replacement parts for the Stanley? Like can one buy a boiler or motor etc? I needed a new boiler for my car and ended up building it myself. If you go to the Restoration section of the web site I describe how I built my boiler. If you do not want to build your own, there are several people that do make them. The reason I made my own is that I needed a condensing car boiler and those have the flue tubes welded in place. The ones you can buy are for non-condensing cars where the flues are not welded. I have been trying to keep my car as original as possible thus the desire to make the boiler a condensing boiler with welded tubes. As for the Stanley engines, yes they are available
