    Question

    A Thermal station has following data:
    Boiler efficiency = 75% Electrical Efficiency = 50% Turbine efficiency = 80%
    Calculate overall efficiency of the plant.

    A.

    31%

    B.

    30%

    C.

    29%

    D.

    35%

    Correct option is B

    Boiler efficiency  =75%,
     Electrical Efficiency  =50%
     Turbine efficiency  =80%
     Overall Efficiency  = Boiler efficiency  × turbine efficiency  × generator efficiency 
    =0.75×0.5×0.80
    =0.30 =30%
