Features of prolongation of the service life of high- and intermediate-pressure rotors of K-200-130 steam turbine of Luhansk TPP
Journal Title: Проблеми загальної енергетики - Year 2018, Vol 0, Issue 2
Abstract
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.
