| description | At present, there is a significant quantity of DTEK “Energo” power units that already worked for their park lifetime. In particular, this concerns the K-200-130-3 steam turbine of 9th power unit of DTEK “Luhansk TPP”. There arises a necessity to make decision on the possibility of its further service. We estimated its residual lifetime based on 3D-spatial analogs of high- and intermediate-pressure rotors of the K-200-130-3 steam turbine of 9th power unit of DTEK “Luhansk TPP”. Here, the experimentally obtained safety factors of metal strength were taken into account, and the actual conditions of operation were determined according to the data of metal damage, obtained by the results of inspection of the state of metal of the power equipment. Recommendations for the re-prolongation of service lifetime of high-temperature power equipment are considered. |

У ДТЕК «Енерго» є значна кількість енергоблоків, які відпрацювали парковий ресурс на сьогоднішній день, серед них енергоблок № 9 ДТЕК «Луганська ТЕС» потужністю200 МВт з паровими турбінами К-200-130. Виникає необхідність прийняття рішення про подальшу експлуатацію. Проведено оцінку залишкового ресурсу на базі 3D-просторових аналогів для РВТ і РСТ парової турбіни К-200-130 потужністю 200 МВт блоків № 9 ДТЕК «Луганська ТЕС» з експериментально отриманими коефіцієнтами запасу міцності металу і урахуванням реальних умов експлуатації згідно даних пошкоджуваності, отриманих за результатами обстеження стану металу енергетичного устаткування. Розглянуто рекомендації щодо повторного продовження терміну експлуатації високотемпературного енергетичного обладнання.
