The NFPA 750 standard defines “water mist” as a water spray discharged through a nozzle in which 99% of the water spray’s volume comprises water particles less than 1,000 microns in diameter. A water mist system combines the key suppression mechanisms of heat absorption, oxygen displacement and radiant heat blocking to control, suppress and extinguish fires. In addition, water mist systems provide the following advantages over other systems: superior fire suppression, smoke absorption capability, minimal water damage, non-toxicity, non-asphyxiating, and environmentally friendly. Wind generators have become very popular lately as a means to generate power for today’s life. The height of wind generator is always 60 to 70 meters. If the cabinet is in fire, it will be hard to response for fire fighter. A fixed fire suppression system is a good solution for fire protection. For the good performance of water mist system, this study wants to develop a water mist system for wind generator fire protection. Through series of fire tests, the water mist system is proofed to have good effectiveness on fire suppression in wind generator fire.
