The authors of this article already presented reports and publications to the attention of public at large [1][2][3][4][5], in which the specific features of steam turbines intended for use in advanced projects of combined cycle power plants (CCPs) were considered. We also gave a detailed description of the projects of prospec tive steam turbine that subsequently became real projects of cogeneration steam turbines for cogenera tion stations (CSs) and district power stations under construction. In [6][7][8][9][10], the specific features of steam turbine designs, layout solutions, and basic process circuits of the turbine units developed by the Ural Tur bine Works (UTZ) for CCPs were shown. In [4], it was pointed out that, in order to support the investment program aimed at development of the Russian power industry [11,12] with relevant equipment, the Minis try of Power and Industry should work out and approve a series of standard sizes of modules comprising a gas turbine unit (GTU), a heat recovery boiler (HRB), and a steam turbine unit (STU) for construction of CCPs. This will make it possible not only to shorten the time taken to approve and implement power sta tion construction projects, but also to reduce the cus tomers' costs spent for procuring dedicated equipment manufactured under a single order.We also pointed to the need to approve a series of standard sizes of main power generating equipment, as a result of which Russian manufacturers will be able to reduce production costs and strongly compete with foreign vendors, and the personnel of power generat ing enterprises will obtain modern serially produced and well elaborated equipment [4].In each new project of a turbine unit intended to serve as the steam part of a CCP, modern design and technological proposals were applied, the use of which makes it possible to solve a whole set of technical eco nomic, schematic, layout, and operational tasks with achieving high indicators of reliability and repairabil ity of main and auxiliary power equipment.In this article we would like to emphasize the most interesting and innovative solutions adopted in these projects and to show the development of some ideas and components from the first projects to subsequent ones. THE T 53/67 8.0 STEAM TURBINE FOR THE PGU 230 COMBINED CYCLE PLANTThe T 53/67 8.0 cogeneration steam turbine has been in operation since 2008 as part of the CCP installed at the Minsk TETs 3 cogeneration station, which comprises a 160 MW GT13E2 gas turbine pro duced by Alstom and a heat recovery boiler produced in Slovakia.The T 53/67 8.0 turbine is a two cylinder machine developed on the basis of a serially pro duced Tp 115/125 12.8 1 turbine. The design of the T 53/67 8.0 turbine incorporates both well elabo rated solutions and fundamentally new ones, the latter connected primary with the fact that this turbine was designed to operate as part of a CCP [6].The use of a throttle steam admission system in the turbine generated the need to design a new external valve cluster. Such a solution made it poss...
