What is a High Velocity Spray System?
High Velocity Water Sprinkler System is used to protect equipments like transformers, circuit breakers, diesel engines and fuel oil storage tanks, turbo alternator lube oil systems and oil fired boilers.
This system has been designed to extinguish oil fires (Water spray systems are installed to extinguish fires involving liquids with flash points of 65° C (150 ° F) or higher.)
The system is based on the principle of “emulsification” for extinguishing Fire, along with the cooling and smothering effect created by the jet of water. The specially designed nozzle sprays water , creates a fine mist , due to the discharge at high velocity . The water jet forms a cone of coarse spray of uniform density which is discharged over a defined area. The coarse spray is able to penetrate the flame zone and reach the surface of the burning oil and brings a fundamental change in the nature of the flammable liquid. It causes the oil to be broken up into tiny globules to form a temporary emulsion with water that cannot burn. In addition, the dispersion of oil into the minute globules in the water gives instantaneous cooling, thus preventing formation of oil vapor.
The system consists of water spray nozzles, sprinkler bulbs, deluge valves and piping. This system employs either wet pilot or dry pilot actuation.
The nozzles used in this system are specifically designed to discharge a jet of water at high speed. The shape of the spray cone, the fire area contacted and the water flow is all controlled by the nozzle specifications – the orifice size and the shape of the internal swirl plate – along with the water pressure and the orientation of the nozzle.
FAQ's
It is an effective way to protect the hazard building or area from fire.
The various types of nozzles are used for spray system based on the surface structure.
To design a powerful system, these nozzles are positioned to mark its unique function.
These systems are started manually or automatically.
The water is sprayed to cool the fire affected product or area. It prevents in spreading fire further and helps in reducing the damage caused by the fire.
These systems are also used where the fire can spread rapidly due to the flammable materials. They are also a perfect system for aircraft hangars fire protection.
For designing a contemporary spray system, the most important part is to properly connect the number of nozzles. The piping setting, the distance of sprinkler from the goal, sufficient amount of water pressure, flash points, concentration & velocity of chemicals present in the building/area and several other factors need to be kept in mind. The designs of such fire protection systems are developed by professional engineers who have deep knowledge of how to design a system to meet the industrial needs for fighting fire.
