Modernization of exhaust hoods of low-pressure sections of Steam Turbines manufactured by the Ural Turbine Works
Thermal Engineering, 2014Co-Authors: A. A. Yamaltdinov, Yu. A. Sakhnin, A. Yu. Ryabchikov, S. Yu. Evdokimov, S. V. SergachAbstract:Issues of modernizing the current exhaust hoods of low-pressure sections for Steam Turbines manufactured by the Ural Turbine Works and designing new ones with the use of modern methods of computational fluid dynamics (ANSYS CFX) are considered. A flow in the exhaust hood is simulated numerically. Verification of obtained data is performed. The use of the finite volume method allowed the three-dimensional flow in the exhaust hood of Turbines of the T-100 series to be analyzed and a simple variant for improvement of its characteristics to be developed. The project data on the novel design of the exhaust hood for the T-125/150-12.8 turbine are given.

Steam Turbines of the T-50/60-8.8, K-63-8.8, and Tp-100/110-8.8 types destined for modernization of thermal power plants with K-50-90 and K-100-90 Turbines
Thermal Engineering, 2012Co-Authors: A. Ye. Valamin, A. Yu. Kultyshev, Yu. A. Sakhnin, M. V. Shekhter, M. Yu. StepanovAbstract:This paper describes the design, schemes of regulation, and control and protection of Steam Turbines of the T-50/60-8.8, K-63-8.8, and Tp-100/110-8.8 types destined for modernization of thermal power plants with replacement of K-50-90 and K-100-90 Turbines that have very low efficiency and exhausted not only their designed, but also fleet life. The replacement proposed is based on state-of-the-art engineering solutions and will be carried out at concrete thermal power plants and CHP plants.

operational improvements for startup time reduction in solar Steam Turbines
Journal of Engineering for Gas Turbines and Power-transactions of The Asme, 2014Co-Authors: Monika Topel, James Spelling, Markus Jocker, Magnus Genrup, Bjorn LaumertAbstract:Solar Steam Turbines are subject to high thermal stresses as a result of temperature gradients during transient operation, which occurs more frequently due to the variability of the solar resource. In order to increase the flexibility of the Turbines while preserving lifing requirements, several operational modifications for maintaining turbine temperatures during offline periods are proposed and investigated. The modifications were implemented in a dynamic thermal turbine model and the potential improvements were quantified. The modifications studied included: increasing the gland Steam pressure injected to the end-seals, increasing the back pressure and increasing the barring speed. These last two take advantage of the ventilation and friction work. The effects of the modifications were studied both individually as well as in different combinations. The temperatures obtained when applying the combined modifications were compared to regular turbine cool-down temperatures and showed significant improvements on the start-up times of the turbine.
