Extending the time-to-overhaul of T-250/300-240 turbines built by the ural turbomotor plant and managed by Mosénergo

The paper discusses the condition of 19 turbines operated by the publicly owned joint-stock company Mosénergo, which have exhausted their time to overhaul (220,000 hours, 600 starts). An extension in the time-to-overhaul of all 19 turbines to 300,000 hours or 900 start ups with the condition that a number of mandatory measures be taken is an acknowledged possibility, based on calculations performed and analysis of damage sustained. A number measures, which have themselves been positively recommended for certain turbines, are examined, and a procedure is presented for evaluating the effectiveness of their implementation. __________ Translated from élektricheskie Stantsii, No. 6, pp. 4–8 (2006).
