In normal "straight
through" systems, the
particles are normally
swept through and dispersed
without being noticed.
In systems that are circulating
or contain settlement
areas then some measures
may be needed to make
sure that these are removed
either by filtration or
flushing.
In the main, the subject
never arises. Domestic
kettles, for instance,
may need a twice weekly
gentle brush and rinse
to expel any soft residues.
This has been accepted
by customers to be a small
price to pay for the removal
and prevention of hard,
caked scale deposits. |
