MODULAR, PERMANENTLY INSTALLED TUNNEL FIRE PROTECTION SYSTEM
First Claim
1. A fire extinguishing system sectionized in sections for fire protection of elongated cavities, characterized in that it actively fights fires in one or more tunnel sections with water which is supplied to low-pressure water mist nozzles via a pipe system and which is distributed from the nozzles in the tunnel section with fire as well as its neighbouring sections in the form of a low-pressure water mist spray, a minimum of 90% of the volume of the water being distributed in drops with diameters of less than 0.001 m.

Abstract
The invention relates to an interconnected module sectionized fire extinguishing system for fire protection in elongated cavities, which is characterized by consisting, in the cavity, of a number of intercoupled section modules in the longitudinal direction of the cavity, said section modules being characterized by being provided with a control valve connecting a water mist nozzle system to water supply pipe with an applied water pressure of 4 bars to 16 bars, and where, in case of fire in the cavity, section modules distribute low-pressure water mist in the form of finely divided droplets in the volume of the cavity in which there is a fire and in the area of coverage of a section module on both sides of the area of fire, and where the distributed water drops are characterized by 90% of the volume of water being constituted by water drops with a drop diameter of less than 0.001 m.
