Abstract
A fog or mist generating nozzle assembly produces a swirling fog pattern having a forward thrust component that permits an operator, stationed safely at a remote location relative to a fire source, to exercise directional control and positioning of a relatively large mist cloud on or about the fire source. The discharge nozzle includes a cylindrical bearing member and a cylindrical rotor member with multiple water discharge orifices that extend at a forward projection angle a relative to the nozzle axis. A pair of fog producing nozzles are configured with counter-rotating rotors, producing counter-rotating clouds that merge along a common vortex. This generates a composite mist cloud having a magnified forward thrust component, enabling remote directional control of the mist cloud.
Claims17
Fire fighting apparatus for projecting a cloud of water droplets onto or about a fire source comprising, in combination:
- nozzle apparatus for projecting clockwise rotating and counter-clockwise rotating clouds of water droplets;
- and
- support apparatus attached to the nozzle apparatus for directing forward movement of the counter-rotating clouds for merger along a common vortex.
A method for projecting a cloud of water droplets onto or about a fire source comprising the steps:
- projecting a clockwise rotating cloud of water droplets in a swirling pattern that has a forward thrust component;
- projecting a counter-clockwise rotating cloud of water droplets in a swirling pattern that has a forward thrust component;
- and
- merging the clockwise rotating cloud and counter-clockwise rotating cloud along a common vortex trajectory.
