plants for ALFA-LAVAL (1990)
In most large ships, specially passenger ships, there is a large consumption
of fresh water. At the same time huge engines have pretty hot cooling
water let into the sea.
Utilizing wasted heat and partial vacuum from the engines, seawater
can be boiled in multiple steps at still lower temperatures if combined
with vacuum in inverse ratio. Rather cold water leave the wessel,
and freshwater is produced in large scale.
The design is a building set with logical structure and parts, that
make it possible to get the parts into existing ships.
The saline water are agressive, so sophisticated alloys and other
materials are used.
Vacuum cooking for dringking water production do have further perspectives
- units are now usen i powerplants and the Arabian Gulf.
ALFA-LAVAL sales are in upper 2-digit mill.$
4 unit plant is 723cm long and 266 cm high
advanced alloys do not need coating to prevent corrosion
