markymark is right, if you look at it long enough, the way the alternating windows cast winding shadows all the way down this hall almost makes it seem like it starts to spin and spiral. . . Freaky!
Yes this is a reciprocating steam engine driving an electric generator. This type of engines appears to be what is called a uniflow but without closer looks it is hard to tell. It is a good looking engine and does look like everything is there. It could probably be run on steam if it were properly drained of the condensate when they stopped using them
Motts, I love the work you do with perspective. You're so daring with your camera angles - I'd be chicken to try a shot like this on anything but a digital (where I could toss it if it were horrible)!
The insulation on the pipes are in fact to keep the steam inside at a high temperature. If it loses temperature then it starts condensing back to water. It has nothing to do with not heating the room or not burning someone. It is entirely a matter of making the equipment run correctly
These are obviously reciprocating steam engines. The jacket is insulation so you do not lose heat. When you do lose heat you lose efficiency and the engine then runs poorly and is costly to run. About the question on heat of steam. Heated water under pressure at 200PSI is 400 degrees hot. The steam in turn can be superheated to 750 degrees and more depending on the type of superheater unit. It is amazing that these old engines are still in place
I love the subtle patterns that the light coming through the windows makes on the ceiling (was that sentence gramatically correct? I really had to think about it hard. . .)
