文摘
The design, schematics, and arrangement of a T-295/335-23.5 turbine and the basic features of a steam-turbine unit (STU) intended for replacement of STUs with a T-250/300-23.5 turbine with the expired service life and installed in large cities, such as Moscow, St. Petersburg, Kiev, Minsk, and Kharkov, for heat and power generation are considered. The basic solutions for an automatic electrohydraulic control and protection system using high-pressure (HP) technology are described. As the turbine operates in a power unit together with a supercritical boiler and the design turbine service life of 250000 hours must be attained, turbine component construction materials complying with these requirements are listed.
