When they are repairing the generator while the steam pressure builds up...how about simply letting some steam pass to reduce the pressure? Or even better, diverting the steam away from the generator during repairs?
For a bunch of supposed engineers and mechanics, they did this the stupidest way imaginable.
I think you gotta suspend any hope for sound engineering practices when you watch this show.
She climbs into the heart of the generator with a wrench and temporarily fixes it. Uh huh.
What really cooks noodles is when the team finally reopens the steam gate, we don’t even see the steam pushing against the wide open turbine blades, which would cause it to rotate and generate electricity. Instead, it just rotates on its own…
shareYes, it was quite the steamed noodle-cooked situation.
shareI got it !
It was a special twin chamber generator doohicky , there was another set of intact enclosed blades just below , so when steam came back those blades it spun the shaft and the exposed blades
They just showed a complete ignorance of planning. Looked like there were no contingency plans for failures along the way, like if the steam generated too much pressure, etc. Lazy writing?
shareTheir engineers were so smart, that they needed their top engineer to hold a water host and nearly get drowned in the process instead of putting the intern to do the job. I am also not so sure about the hot gas hitting the cold water as soon it is released
shareShe water-quenched a steel door that was red hot and it didn't crack. Of course, it's a glass door now...
shareSo does everything a blacksmith puts in the quench bucket turn to glass? makes you wonder why they do it.
Water quenching typically causes cracking and brittleness in steel. Especially the harder steels.
Oil quench is preferred for this reason.
Water quenching causes steel to become harder (resistant to its surface being scratched/penetrated) but more brittle. It also can cause the steel to crack if it was hot enough.
shareIt's a TV show.
shareThe whole thing about the generator was idiotic, and how no one seemed to understand how to run it or how it worked. As it is having problems rivets are popping out of the pipe unions ... and it still works fine. That part is brain dead. The original designers would have allowed for dissipating pressure build up - anyone would know that.
And of course they would have designed redundancy into the system if they wanted it to last generations.
