Last stage blade materials and exhaust steam wetness shall be selected to minimize blade erosion. 2 FCB function introduction FCB refers to when the unit is in the conditions of boiler no failure, the boiler can quickly load reduction, decrease the rate of boiler combustion, guarantee the stability of the main steam parameters, ready to restore the power grid load and running, FCB has three types: (1) generator is having external fault, such as low frequency, out of step and so on, steam turbine no trip, continue to run with auxiliary power load; (2) generator transformer unit internal fault interlock trip turbine or steam turbine fault tripping, boiler keep steady combustion; (3) generator is having some faults, such as over-voltage, generator tripping and so on, but steam turbine no trip[5-7].
