Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Significantly reduces water consumption, allows efficient fire extinguishing without capital-intensive infrastructure, and is suitable for areas with limited water resources, effectively directing fire-extinguishing agents to ignition sources.

Implementation Method 1

water is ejected in small quantities and delivered in spray form in the nitrogen stream

Methodology Applied
Scientific EffectSpray: Spray

Implementation Method 2

water particles that have enough energy and a high initial velocity increase the jet range, and as they enter the high-temperature area they vaporize and absorb a significant quantity of heat

Methodology Applied
Scientific EffectVaporization: Evaporation

Implementation Method 3

nitrogen displaces oxygen from the ignition area, and as the specific oxygen content decreases below 10%, burning stops

Methodology Applied
Scientific EffectGas displacement:

AI summary

Achieved is a significant reduction in water requirements and use of an accessible alternative fire- extinguishing medium for which there is no need for a pumping station, a water supply source, and an electric power substation. This is achieved in a robotized nitrogen -water fire - fighting complex comprising two or more robotized fire - fighting units (1) mounted on a pipeline (2); a control panel (7), a control device (10) generating control instructions for barrel pointing and fire - fighting; an ignition detection and remote observation device (11) mounted on the barrels, being connected to a video signal processing device (17) determining the coordinates of the ignition sources, and connected to the video monitoring device (14) and the control device, the complex further comprising a nitrogen generator (23) connected to a receiver (22) containing nitrogen and connected to the pipeline for supplying nitrogen to the carriage -mounted barrels (3), and ejecting devices (24) supplying water into the nitrogen flow.
