Fire Fighting and Firejector Technology

The Firejector is a fire control system that uses a high pressure fine mist entrainment to extract and direct smoke flames and gasses from a structure.

The Firejector system that has the potential to reduce injuries, deaths and loss of property resulting from fire. The ‘Firejector’ principle can improve fire fighting performance, and effectively prevent fire in many situations. There are many advantages with the Firejector entrainment system. Fire can be controlled without firefighters having to enter smoke filled areas and smoke is removed rapidly from confined spaces. Search and rescue is more effective and less hazardous and there is a significant reduction in fire, smoke and water damage.

Please click the two short videos below will show how large volumes of ultra fine mist explain the principle of entrainment

Firejector Potential

A firefighting system that has the potential to reduce injuries, deaths and loss of property resulting from fire. The ‘Firejector’ can improve fire fighting performance, and effectively prevent fire in many situations. There are many advantages with the Firejector entrainment system. Fire can be controlled without firefighters having to enter smoke filled areas and smoke is removed rapidly from confined spaces. Search and rescue is more effective and less hazardous and there is a significant reduction in fire, smoke and water damage.

The basic principles : The Firejector uses the powerful entrainment force created by large volumes of high velocity, ultra fine mist water droplets to control fire and gasses. The materials entrained include flames, heat, smoke, gasses, burning brands, dust and hazardous or explosive airborne substances.
Heat absorbed by the suspended droplets cause an expansion force that increases the velocity and volume of the entrained mist mixture.

The Firejector is positioned and directed to entrain the flames, heat and smoke out of the fire-site. After the first unit is activated a second unit can be positioned to force volumes of high speed mist into the fire-site area.

A test shows how fine mist can entrain fire

**Early prototypes open for more research and development**

The units displayed are origional prototypes, potentail exists for more research and design development.

THE RANGE OF APPLICATIONS INCLUDES:
• Structural fires • Hazardous Materials • Aircraft • Marine • Mine shafts • Fuel Storage • Vehicles • Explosion Prevention • Warehouses • Multi-story Structures • Pipelines • Gas/Oil Wells • Inaccessible Spaces • Dust Control • Grain Storage

Some of the advantages of the Firejector system include:
Saves lives of firefighters and fire victims
Controls fire and smoke without firefighters having to enter heavily smoke filled areas
Smoke is quickly removed from confined spaces
Search and rescue is less hazardous
Significant reduction in fire, smoke and water damage
Efficient use of limited water supply
Increases fire crew effectiveness
It can be installed in seconds and left to operate unattended
The system eliminates the spread of fire from flying brands, radiant or convective fire spread.
The unit has no moving parts

Testing specific nozzle designs and configuration for maximum entrainment

The Firejector’s entrainment of smoke, flames, heat and gasses is a force created by the specific pattern, speed and form of the mist produced by the manifold. Precise nozzle design, the angle of discharge, spray pattern distribution and several other factors are calculated into the nozzle manifold.
High water pressure can create significant volume of airflow reaching speeds in excess of 100 kms per hour. When flames and/or hot gasses are entrained by the fine mist an instantainious expansion creates an increased power.

Oil, gas or industrial applications I invented this concept during the First Gulf War 1990

A Firejector control and extinguishing system for high intensity fires e.g. oil well fires, or large volume gas leak to prevent an explosion.

Using a fireproof tube and high pressure water the nozzle system generates a force
sufficient to entrain or vacuum the flames or gasses from the well-head through
the pipe and directing the mixture
to a safe discharge area. The mixture of high pressure mist and flamable liquid or gas is not combustable inside the pipe.

Multiple design options

These simplified sketches show the fundamental concepts and aspects of the potential applications. The mist entrainment principle can be adapted to many situations. Large systems installed in mines, lite-weight portable systems, explosion and fire control systems installed in buildins,aircraft, ships, industrial structures etc.
