from HTF piping and equipment
exist. Consideration may be given to
automatic leak-detection systems,
coupled with the capability to de-energize
area electrical equipment and
activate zones of water fog deluge systems
and alarms. If ventilation is activated,
it may negate the desired effect
of water fog sprays in scrubbing the
HTF mist from the air. Pooled or contained
DP:DPO liquid settles to form
a bottom layer once it has cooled to a
temperature at which its density is
greater than the density of the water.
For any of the above approaches for
fire response, consultation with insurance
providers is recommended.
Final ThoughTs
The primary intent of this paper is to
stress the importance of good design,
installation, and maintenance of equipment
in DP:DPO handling facilities in
preventing HTF release and fire events.
By keeping the HTF within the piping
as intended by robust design, the
frequency, severity, and consequences
of leaks and fires can be minimized or
even prevented altogether. All components
of a complex HTF system cannot
be addressed within the context of this
paper, therefore the designer and facilAuthors
