BTW cRusty, why didn't they replace the submerged basket type evaps with flash-type during reactivation/modernization? They take much less and appear to have less problems.

Absolutely Pal. Got to have water and lots of it!
The rules I learned long ago: the three mains
1)Steamflow (Pressure)
2)Feed flow (fuel)
3)Drum level. (water)
The evaporators onboard make up to 120,000 gallons of boiler feed and potable water per day. The boiler feed water must contain less then .2 parts salt per million gallons and treated with boiler compounds to reduce any minerals running through the system that can prematurely eroid the tubing especially the tubing bends where the wear is much more abrasive.
