Moscow. July 3. INTERFAX - Gazprom (MOEX: GAZP) is preparing to start production on its own of an improved version of the popular model of the Soviet marine engine. Also, the concern has prepared a plan for its further improvement: with an increase in efficiency and power.
The Tyumen Motor Builders enterprise (part of the Gazprom Energoholding Industrial Assets group) will produce a 16 MW gas turbine engine. As part of the project, it was named TM-16.
The model is an improved version of the GTD DG90 developed in Nikolaev of the Ukrainian USSR. This is one of the most popular drives of natural gas superchargers. More than 300 such engines are currently in operation at Gazprom's compressor stations.
Andrey Bronnikov, Deputy Head of the Gazprom PJSC Department, notes: "Its widespread use is due to its high reliability, maintainability, and competitive cost. The production of this gas turbine engine began in 1989, but not enough attention was paid to modernization issues. As a result, today the DG90 does not meet modern requirements in terms of efficiency and environmental friendliness."
"The rupture of cooperative ties between enterprises has complicated the situation, and now it is necessary to make decisions on the development of the manufacture of DG90 on the territory of the Russian Federation and its improvement," writes Bronnikov with co-authors from PJSC Tyumen Motor Builders, LLC NPF Thermophysics (Ufa), Tyumen State University and the Central Institute of Aviation Motor Engineering named after P.I. Baranov (CIAM) on the pages of the magazine "Gas Industry".
The release of the TM16 model is the first stage of modernization of the DG90 engine. It provides for an increase in efficiency from 34.1% to 35%. This is planned to be achieved through the use of new superalloys with increased heat resistance for blades, new profiling of low and high pressure compressor blades. It is also planned to improve the environmental characteristics of the combustion chamber.
The release of the head sample of the TM16 engine is scheduled for 2025.
"In the future, TM-16 can be used, among other things, to replace imported engines of similar capacity that have run out of life," Gazprom said following the results of the agreement signed with the Tyumen Region for SPIEF-2023. The Tyumen Engine Builders plant will provide the development of design and technological documentation, on the basis of which a prototype engine with high technical, economic and environmental characteristics will be manufactured.
Stanislav Gut, CEO of Tyumen Motor Builders, commented to Interfax: "The implementation of the TM-16 project is an important incentive to reach a qualitatively new level of development of our enterprise. The experience accumulated at the Tyumen production site of major repairs and maintenance of gas turbine engines and gas turbine engines allows us to find the most optimal design and technological solutions for creating a modern gas turbine engine, combining all the best practices in engines of previous generations and modern innovative materials and technologies."
perspective
The second stage (TM16M model) provides for bringing the efficiency of the engine to 37.5% due to a moderate increase in the limiting parameters of the thermodynamic cycle, aerodynamic improvement of the blade devices and the cooling system. "New CIAM design techniques can significantly improve the aerodynamic efficiency of the path, and the achievements of VIAM (All-Russian Research Institute of Aviation Materials) in the field of superalloys create the potential to increase the resource of the most loaded blades, reduce air consumption for cooling or increase the temperature in front of the turbine," the authors of the article note.
The third stage involves the creation on the basis of TM16 of a new gas turbine engine with a capacity of 25 MW and an efficiency of 40% due to the installation of an intermediate air cooler between the compressors.
"As a result, the efficiency of the V-generation GTD can be achieved already on existing and available technologies of the II-IV generation. The design of the heat exchanger is made as efficiently as possible and organically fits into the gas-air tract, while the possibilities of additional size reduction due to the transition to super-compact heat exchange cells have not been exhausted. Advantages of intermediate cooling: lower price (compared to analogues), theoretically higher reliability and life of the gas turbine engine, and the temperature of the coolant at the outlet allows its use in heating systems," the authors of the project write.
