Water Mist Fire Protection Steam TurbineSteam turbine generators are a common source of energy production for public utilities and industry.  The efficient operation and availability of these turbines are of the greatest importance.  Outages caused by unexpected shutdowns lead to significant financial losses and higher generation costs.  The turbine’s ability to operate smoothly and efficiently depends on the bearing lubrication system.  If for any reason lube oil flow is interrupted, then the spinning rotor shaft will make metal-to-metal contact with the inner bearing surfaces.  The failure of the bearing can result in catastrophic damage and extended outages.
