Deluge
Water Sprinkler System
 |
Deluge
Systems,
as the name implies, deliver large quantities of water over
specific areas in a relatively short period of time. These systems
are used to protect against rapidly growing and spreading fires,
typically involving flameless liquids, solvents etc.
Deluge
Water spray systems are similar to automatic sprinkler system except
all nozzles are open and will discharge together when control valve
opens. These systems are designed to protect areas where fire is
likely to spread rapidly and / or where cooling of surrounding
equipment is necessary. |
Deluge
Waterspray Systems are similar to sprinkler systems in that they control a
water supply. Control valves, piping, hangers, and discharge devices.
As
such, these systems also require the same inspection, testing, and
maintenance as sprinkler system. However, water spray systems can have, in
addition to these items, a detection systems that is hydraulic, pneumatic,
or electrical, other devices such as pipeline strainers (not normally
found on sprinkler systems), and devices required special attention in
order to maintain the operation status of the water spray system.
Water
spray systems are designed to direct water at a required density, from
nozzles having predetermined patterns to completely impinge water onto the
hazard surface being protected. They are designed for use in a variety of
special hazards applications including flammable and combustible liquid
hazards, transformers and turbines.
In
some circumstances extinguishment is not always desirable, only cooling.
Common applications include power generation equipment (e.g. switchgear),
flammable liquid storage, gas tanks and process plants.
Cooling
is achieved by the use of medium velocity spray nozzles and extinguishment
is usually by high velocity nozzles.
This
system can be activated manually or automatically by hydraulic, pneumatic
or electrical detection systems.
This
type of system also needs sufficient water flow and pressure to contain or
extinguish the type of hazards they are there to protect.
