| Abstract: | Taking the thermal cycles of two 300 MW units,installed in a certain power plant,which in the past often incurred tube leakages in the H.P.heaters,steam gland leakages,excessive terminal differentials of H.P.heaters,too low a temperature rise of condensate water in the No.1 L.P.heaters etc.,as the object of study,the harm done is being analyzed and the causes of the failures diagnosed.Ways of retrofit are being presented,with which various problems of the thermal cycle have been solved with the effect,that normal operation has recovered and the sets' profitability raised.Figs 3,tables 2 and refs2. |
