Lesson.... at 50 meters high

On the roof of the boilerroom of unit EC 3.
Wytze is giving lessons about expansionbends to our trainee.
Why?
Well the trainee Sander saw the auxiliary steampipe at the roof of the new auxiliary boiler, 40 meters below us and did not understand why there was a "funny" bend in it....
It took some time to explain....
There is a Dutch proverb saying: "Eén gek kan meer vragen dan tien wijzen kunnen beantwoorden", In English I think: "one mad mad can ask more then ten wise men can answer".
We tell him all we know and hope it will arrive.
We experience that the schools do not much about mental arithmetic.

Here in LARGE....

Unit EC 3 still in overhaul, the gasturbine is being fitted with burners and manifolds .
