THis looks like an impingement mill for the pulverized coal system...huh guys?

These look like the induced draft fans. They would help carry hot gasses up the chimney. There would be a heat exchanger somewhere in this assembly to send to the forced draft fans in the basement.

That's the suction side valve that has been semi-mothballed. They were probably going to use it elsewhere if necessary. But since it carried river (or worse) water, it was subject to rapid wear. When they took the main cover off that condenser, they never intended for it to go back in service. That was the end. These units are actually quite small by today's standards. Probably not more than 50-60 megawatts at the most. I doubt if they ran on steam pressures greater than 500 psig, if that. You don't really find the 100Mw and greater units running at 1050 psig until the mid-50s. These units are "cute." And the pictures are fabulous! I've got some pix of me at a 25 Hz unit in the 70s. I'll scan it and send it out one of these days.

Ooh, sorry, that's another condenser. The boilers are in another building (the one with the smokestacks. Got any pix of them? Iif there are, I'll find them.) I used to clean these things when I was a plant operator in the 70's. We'd always find them plugged up with algae and crabs. (...mmmmm...crabs!)
