|Fire Extinguisher Nozzle Successfully Demonstrated
The newly developed fire
nozzle from the Naval Air
Warfare Center is tested at
the Allegheny County Fire
Facility in North Park, Pa.
The Naval Air Warfare Center
(NAWC) of Lakehurst, N.J., has been
actively developing an environmentally
benign water nozzle system to replace
halon fire extinguishing systems.
The nozzle was recently featured in
a product demonstration by the Fire
Academy of Allegheny County in
collaboration with the Pittsburgh Bureau
of Fire and the University of Pittsburgh's
National Center for First Responders.
The demonstration, which took place
at the Academy's training facility in
North Park, Pa., was also attended
by International Aero, licensee of the
nozzle technology, and GeoCenters,
Inc., which provides technology transfer
assistance to NAWC.
The nozzle, invented by Joe Wolfe,
effectively atomizes water into
droplets on the order of 10 to 100 micrometers
in diameter using water and air pressures on
the order of 20 psi (a standard hose operates
at around 50 psi). Compared to conventional
hoses, this system results in a much more
efficient use of water to quench and smother
various types of fires in a variety of situations,
environments and conditions.
The benefits of this water delivery nozzle
include a potential substantial decrease in hose
size and weight to sizes on the order of a garden-sized
hose. This eliminates back momentum
forces on a fire hose such that a firefighter
conceivably could hold the hose and direct its
flow with one hand and, if used in conjunction
with foam mixtures, could reduce of the amount
and cost of foam solutions.
