I interviewed a guy for a job yesterday... he was a retired engineer who had done a career in power plants.A naval boiler runs at 500F, under pressure. Now tell me how that moving air theory works again?
He said that in the summer the air temp on the floor runs 120-150 degrees, but in the
winter, small lines freezing was a thing that could happen because the floor is not just open to outside air, it has a tremendous volume of forced outside air hitting it. And he is talking about plants in New York where they expect cold winters!
I really wanted to ask him a million power plant questions, but I also had an interview to do... I hired him though, so I'll ask him later!
Good article on the whole situation over at ars technica.
