//&#;&#;The water droplets help to cool down the flames, which encourages them to go out. Plus, the oxygen available is minimized, and finally, the droplets evaporate as they make contact with the fire which also aids in heat absorption and can help prevent secondary combustion caused by how hot the fire is. Water mist systems release up to % less ...

alternative system that is being used in the market today is a water-mist fire suppression system. The system was initially developed for protection of lumber drying kilns and later for use on ships. When Halon suppression systems were deemed environmentally unsafe in , water-mist systems became the leading candidate for replacement.
The Novenco Fire Fighting (NFF) XFlow&#; water mist system gives you the opportunity to integrate local and full fire protection in a single system. This fire suppression solution can be applied as a total flooding system, local application fire fighting system (LAFF) and for accommodation areas.
Description of water mist or similar innovative systems A water mist system is a fixed fire protection system. The system comprises components for detection and actuation, water supply, water delivery and water atomization. Water mist systems discharge a spray of small water droplets.
Water mist fire suppression technology has attracted an increasing interest from the field of fire protection services such as fire safety for buildings, ships, spacecraft, libraries and museums ...
as reliability. Conventional low pressure water spray or sprinkler systems can cause considerable water damage, which is often higher than fire itself. Extinguishing fires with water mist is a superior method to most alternatives, due to its efficiency and cleanliness.
//&#;&#;A further highly beneficial effect of high pressure water mist is the dramatic reduction of harmful products of combustion caused by the washing out of smoke particles from the fire. Nozzle Selection. Nozzle specifications are central to the performance of the water mist system, to ensure correct coverage and fire protection.
This paper presents some preliminary results from a reliability study of water mist systems conducted at FM Global. The study includes a detailed Failure Modes and Effects Analysis (FMEA) to identify all the major potential failure modes, which include demand, quiescent and operational failures.
//&#;&#;Water mist systems are becoming an increasingly popular alternative to total flood carbon dioxide systems, which can be dangerous to workers. With low, medium, and high pressure systems available, water mist systems can do everything from creating a fire suppressing fog to replacing traditional sprinkler systems.

The calculated failure probabilities results and the confidence bounds of the selected water mist systems should be considered as preliminary estimates because the data used for the. ... WATER MIST FIRE PROTECTION RELIABILITY ANALYSIS .
MicroMist&#; is a self-contained, single fluid, pre-engineered water mist fire suppression system that is at the forefront of new environmentally friendly fire protection technology. It is used for total compartment protection of hazards such as machinery spaces, diesel generator sets and compartmentalised gas turbine generators.
//&#;&#;The analysis shows that traditional automatic sprinkler systems have high reliability, with the reliability of water mist systems being of the same order but slightly lower. According to the source, the strength of a fault tree analysis is that, in principle, it can be applied to
The Water Mist Fire Suppression Process. Cooling Effect: The small droplets created by water mist systems, increase surface area to maximize the efficient absorption of heat. Oxygen Displacement: The small droplets evaporate rapidly and expand to displace oxygen in the proximity of the fire. Radiant Heat Attenuation: The small droplets provide ...
The GW M Nozzles are water mist nozzles for protection of local applications such as in duct systems and engine bilges. The nozzles are suitable for spraying water mist, as well as water mist with foam enhancement. GW Sprinkler recommends the use of Angus
Powered by tiny water droplets, water mist fire protection systems have some benefits and disadvantages compared to conventional fire sprinkler systems While fire sprinkler systems have worked on the same principles for more than a century, a novel approach to fire protection has gained traction over the past years: the water mist sprinkler system.
This paper presents results from a reliability study of water mist fire protection systems conducted at FM Global.
