turbine bearings are lubricated by oils supplied through a closed system.fires could occur from accidental release and ignition of the oil and if not adequately controlled could result in significant damage to the machineries and disruption to the business.
therefore it is recommended that the turbine generator bearings be provided with fixed,automatically-actuated water-spray system with directional-spray nozzles designed for a density of 0.25 gpm/ft2 over the protected area.coverage should be provided for the seal area and lube oil pipe connections to the bearing housing.For the lube oil pumps and tank installations,automatic sprinklers with a design density of 0.25 gpm/ft2 over the protected area should be provided.The lube oil storage tank should be provided with a bund sufficient to contain the entire content of the storage tank plus 10% in the event of any leakage or spillage of the oil
