Unique Projects of Steam Turbines at AO Ural Turbine Works for Industrial Power Generation

Abstract

The results from an analysis of the Russian market of steam-turbine machine building for various industries are reviewed, including determining the basic features of turbines for this market segment and the requirements imposed upon them. A conclusion has been made that industrial enterprises’ demand for steam turbines will persist during the fourth energy transition. The advantages in developing large consumers’ own generation of heat and power in Russia are outlined. An increase in demand for upgrading and replacement of equipment in the next decade is predicted. Exclusive projects of steam turbines for industrial generation developed at AO Ural Turbine Works (UTW) during the last few years are presented. The selection made includes equipment with an electrical power of 30, 50, or 60 MWel operating at different live steam pressures (2.9, 8.8, or 12.8 MPa) and differing in design types T, PT, PR, or R. The design and process solutions implemented to improve the efficiency of these turbine units within the scope of the individual requirements set forth by the facilities where these turbines are to operate are presented. The main characteristics are presented of the turbines designed for replacing the equipment manufactured in the 20th century without any modification to the existing foundations and overall dimensions of compartments. An approach to the development of modern steam turbine products for the market segment of industrial generation is identified. An engineering criterion for the effectiveness of a turbine unit in case of its continuous operation throughout the year is proposed to select the best equipment for specific operating conditions. The benefit from using an additional criterion at the stage of tender held by the customer for calculation of integral estimation of the annual operating expenses for purchasing electricity by the enterprise is substantiated.
