PURPOSE:To enable secular deformation of a boiler water feeding pump and a driving turbine to be surveyed and diagnosed by detecting the values in operation state of the pump and the turbine and comparing the above data with the data in the past. CONSTITUTION:Each output data on each detection device 13-15 for the temperature, the pressure, and the flow rate of steam and the supplied water and each detecting device 16 for the number of revolution of a water feeding pump and a driving turbine is inputted into an average value calculating apparatus 17 and averaging is performed. Enthalpies H1-3 and H4.5 are calculated in an enthalpy calculating apparatuses 18 and 18 from the average value from each data, and the gained power F1 of the turbine described the above and the power F2 necessary for the water feeding pump are calculated from the above enthalpies in calculating units 21 and 22 respectively. The above calculated values F1 and F2 and the planned value data 25 stored beforehand are inputted into a performance analyser 26, and the results in analysis are inputted into a performance diagnostic apparatus 27, and thus the secular variation in performance of the water feeding pump and the driving turbine is judged and surveyed. |
