Firefighting turbine

from Wikipedia, the free encyclopedia

A firefighting turbine (also known as a fire extinguishing turbine) is a device used to extinguish fires . An air stream is generated by means of special nozzles. The water used is atomized into a mist and distributed over the fire object.

Nozzles of a fire fighting turbine

technology

A firefighting turbine is fitted with a ring of nozzles that atomize water or extinguishing foam into fine aerosols. This water or water-foam aerosol is distributed by means of propellers. The resulting droplets form a large water surface and thus a larger heat transport surface. The fine mist has a lower sedimentation speed , so it can stay in the air longer and contain the fire better. The fine mist floats through the room and also reaches hidden areas of the fire source. Due to the atomization of the water, the amount of water used is reduced. The operating principle is comparable to that of a turbo extinguisher. The mixing of the fine water droplets with the smoke and soot particles also ensures that they are brought to the ground.

Intended use

Fire operations are often associated with strong smoke, soot and heat development. This not only hinders the extinguishing work, but also represents a considerable danger for employees, residents and rescue workers. Fire-fighting turbines generate a very high cooling capacity and are therefore able to extinguish fire objects more quickly. Fire-fighting turbines are primarily used in the chemical industry and refineries, tunnel and subway shafts, airports, forest fires and recycling plants.

Fire extinguishing turbine in use

use

Extinguishing turbines can be placed on mobile chassis for defensive fire protection , such as on the superstructure of fire trucks or on self-propelled crawler chassis, or they can be installed as stationary systems in a hall for preventive fire protection. Using a remote control, fire extinguishing turbines can be operated up to a range of 500 meters. When deployed, the fire engine is sent ahead, the fire fighting team follows at a safe distance.
