The Steamboating Forum

Oh yes, I have only calculated power plant steam cycles and didn't realize the cycle is usually at atmospheric pressure in condenser. Only theoretic understanding and no practical. Main benefit of low pressure cycle would have been diy boiler, but kind of hard to design all for a prototype. Conventi...

In Finland boilers under 1.5 bar (21.8 psi) absolute pressure (0.5 bar gauge pressure) are not considered as pressure devices that need inspection. If condensator is used, that would give good enthalpy difference, even better if steam is superheated. Steam specific volume would be comparatively huge...

Hello, Simo from Salo, Finland I have never even seen live steam engine. Studied some some thermodynamics in university (well, almost master of science in energy engineering. Most is forgotten, it was a while ago). Now I am apprentice cnc machinist. Been working with cnc lathes for a year. I have ac...
