[Gasification] sexy steam//// what role? In Power? 95%. What role in all else?

[Richard Bockwinkel]

Excellent POINT Mark.

I especially concur with the 95% of grid energy being tied to STEAM.

NOW...can anyone tell me what that 95% relates to with regard to ALL of steam's applications?

Get ready to FREAK OUT.

But in an  isentropic (constant entropy) expansion, such as occurs in a steam turbine, a phase change from vapor to liquid can spell death to the turbine. Often the steam is reheated  along the way, just to prevent “wet” steam.

When checking with Kennedy Tank, a similar boiler can be made using todays materials.  From my research, it is the verticle firetube (and a lot of them) that is key, since the temperature has limits as long as it has ANY water in it.

That boiler was rated at 600psi but my guess is, at the speed record attempt they were well over 1000-1200f.  There is a lot of stored energy in water that is not yet steam (due to pressure) and I often wonder about injecting super heated water into an engine, taking advantage of the 1600x expansion, liquid to vapor.
