Gas turbines
of medium and high capacity

About the project

Nowadays, over 30 GW of power generating plants operate at gas-steam cycle in the territory of the Russian Federation. The share of equipment of foreign companies in the gross installed capacity of the commissioned combined cycle plants and gas turbine plants is over 70 %.

In 2018 in order to provide energy security and energy independence, the Government of Russia took a decision to recreate domestic production of gas turbines.

At the same time, considering its achievements in the field which is conventional for the enterprise, considerable experience in mastering new types of products, as well as its gas turbine plant creation background, Power Machines launched a development programme for modern domestic gas turbines production of the GTE-65 (ГТЭ-65) and GTE 170 (ГТЭ) class.

In 2019 Power Machines won the competition of the Ministry of Industry and Trade of the Russian Federation for the right to receive subsidies for research and development and technological works to produce high-power gas turbines. At the present day, with the support of the Ministry of Industry and Trade of Russia, "Power Machines" carry out R&D activity in cooperation with fundamental scientific research and industrial enterprises of the country - Siberian Branch of the Russian Academy of Sciences, NPO CKTI, CIAM, VTI, CNIITMASH and many others.

Due to this work, in the immediate future Power Machines will manage to bring to the market two fully made-in-Russia gas turbines of 65 MW and 170 MW.

By the end of 2019 the enterprise had recreated a design bureau of gas turbines, a large range of R&D activities was under implementation, domestic suppliers of critical components and fabricated parts were determined, modernization of in-house production and experimental and research facilities was in progress. The pilot commissioning of the first production units of GTE-170 (ГТЭ-170) will be performed in 2022-2023, the same for GTE-65 (ГТЭ-65) will start from 2024.

Gas turbines GTE-65 and GTE-170 can be used as a part of combined cycle plants both in monoblock arrangement with an individual steam turbine and in double-block arrangement with a joint steam turbine meant for two gas turbine plants.

Successful development of gas turbine production technology by the Russian company will reduce the dependence of domestic energy production on the import of this equipment and will ensure the energy and process security of the country.

High-power gas turbine GTE-170 (ГТЭ-170)

  • Description
  • Technical Specifications
  • Structure

The reliable gas turbine is designed to drive an electric generator with a rotation speed of 3000 rpm in a simple or combined cycle. It embodies the requirements of state and industry standards of the Russian Federation. The first production units of gas turbines (version GTE-170.1 (ГТЭ-170.1)) will be of high reliability with cycle parameters being at the level of the most plants operated in Russia.

Version GTE-170.2 (ГТЭ-170.2) with elevated parameters is under development. The Power Machines design bureau of gas turbine plants performs R&D activities in cooperation with the largest scientific organizations of the Russian Federation in order to bring efficiency parameters to the advanced foreign analogue level and at the same time to save high reliability of the gas turbine plant. Several compressor stages, combustion chamber units including burner arrangement, moving and guiding blades, including blade cooling system, will be modified in GTE-170.2 (ГТЭ-170.2) structure.

Production

Production of gas turbine plants is carried out at Leningradsky Metallichesky Zavod (LMZ) of Power Machines. The LMZ plant is mainly engaged in the production of turbines and auxiliary equipment for atomic, thermal and hydraulic power plants and industrial enterprises.

During 2020-2021 the refitting of production facilities with several groups of equipment will be performed in order to fix tight spots. The total volume of planned investment to production refitting exceeds 4 billion rubles. In particular, it is planned to recreate pre-existing operational sequences but at the up-to-date process level, namely:

  • high precision casting of turbine cooled blades of heatproof materials;
  • protective coating (anti-friction, thermal barrier, erosion-resistant) of hot gas path components;
  • assembly operation of gas turbines.

Research and experimental facilities

A trials facility designed for trials of full-scale units of combustion chambers of gas turbine electric power plants of medium and high capacity was commissioned in 2006. At the present day, preparation of the firing trials facility for trials of GTE-65.1 (ГТЭ-65.1) and GTE-170.1 (ГТЭ-170.1) combustion chambers under actual-use test conditions is carried out in order to check how structural solutions affect main performance data and environmental performance: adjustment start modes, variable modes, loss-of-load modes, shutdown modes of the gas turbine plant combustion chambers.
Moreover, the company owns unique testing equipment, including Schenck rotor balancing facility with vacuum chamber, which allows for the testing of standard-size rotors of gas and steam turbines of a capacity up to 1200 MW.
