Quantity and type of spray nozzles
calculation as per NFPA 15 pg 11-15
Density to be applied on vertical surface : 0.25 Gallon
per minutes per sq ft (10.17 Liter per minute per sq
meter)
Brief Case Example
Deck surface area = 24,085 sq ft (2237.54
sq meter)
System water flow discharge rate = 24,085 x 0.25 =
6,031 gallon per minute (22,797Liter/m)
Select Wilson Spiral Full Cone Nozzle "T" series
Model : 3/4T32-150
Flow rate : 166 liter/min @ 3 bar
Size : 3/4 inch male Npt
Material : Brass
Spray angle : 150 degrees Full Cone
Download Catalogue :
T_Series.pdf
Therefore total number of nozzles required @ 3bar =
22,797 divide by 166 = 137 pieces .
Allow for thirty percent (30%) spray overlap, add
additional nozzles as fit
Note : calculation delineated above is to ascertain the
number of nozzles only, pressure loss in the pipe system
need to be calculated separately. |

Large Angle Deflection Principle – Type
FW
FW flat jet nozzles work on the deflection principle
trajecting a stream of water onto a machined deflecting surface,
producing a wide angle flat spray pattern having low impact
value and small droplets.
The
thru hole orifice reduce clogging when dirty water is used.
Applications:- Fire Curtain, Ship side cooling,
bulk head cooling, Oil Rig Hull Cooling, deck cooling, washing
of vertical surfaces, washing fruits on a moving conveyor.
Connection: 1/8" to 1" BSP or NPT
Spray angles: 90° to 140°
Material: PVC, Polyproperlyne, 303 Stainless Steel, 316 Stainless Steel, Brass

Inergen
is an environmentally green three dimensional fire suppression
agent replacing Halon 1301. It is a blend of three
naturally occurring gases--Nitrogen, Argon, and Carbon Dioxide.
The Inergen
discharges through nozzles to ensure optimum distribution in the
protected area effectively suppressing the fire.
