This paper starts a series of articles focusing on the prospects for Gazprom’s gas transport system development. The development of new hydrocarbon production regions, diversification of gas transportation routes to Europe and the development of the Russian territories require construction of highly-efficient and reliable gas transport system. Solving the challenges of gas transportation – the new Yamal-Europe and North European pipelines, from the northern districts of Murmansk Region to Volhov, Altai, gas pipelines from Shtokmanovskoye and Kovyktinskoye fields, and full-scale development of East Siberia and Far East – require the application of new approaches with various technical solutions and capital expenditure levels. This article covers Gazprom’s requirements for the primary technological equipment to be used within the framework of these projects.
Application of gas turbine electric drives in natural gas transmission
Andrey Vertepov, Sergey Zaritskiy – Orgenergogaz
The natural gas compressors operated on the gas transmission pipelines of the UGS (unified gas supply system) are driven primarily by gas turbines. The share of gas turbine compression packages in the total installed capacity is 86%. This raises an issue of reduction of gas used for the needs of compressor stations. Besides, efficiency improvement of compressor packages with standard design is limited by the acceptable cycle parameters. Orgenergogaz offers to improve compressor efficiency through application of new combined alternative drive solutions.
Current methods for solidification of gas turbine blades from heat-resistant alloys
Yuri Kalukin – NPO Saturn
The article reviews modern methods of casting by the formation of equiaxial and directionally-solidified structures, new developments by Saturn in the field of modern equipment construction, and casting from heat-resistant superalloys with equiaxial and small-columnar structures. It also describes the results of investigation into the structure, properties and technological features of HP turbine rotor blades manufactured from DS200 and ChS-88VI alloys with grain size specified in accordance with the requirements of international standards.
Perspective equipment for CHP in Russia
Sergey Zharkov – Melentev Energy Systems Institute, Siberian Branch of Russian Academy of Sciences (Irkutsk)
The wide use of fuel cells (FC) is forecasted at mini CHP worldwide in the nearest future. The article describes perspective equipment for CHP (combined heat and power plant) in Russia.
Aquarius – environmentally friendly technology for power generation and mechanical drive application
Viktor Romanov, Anatoly Kovalenko, Villy Krivutsa, Vladimir Lupandin, Viktor Lupandin — Mashproekt
Since 1986 Mashproekt has been working on development and construction of combined cycle power plants with Aquarius technology featuring injection of steam into the turbine gas path and water recovery from the mixture of exhaust gas and steam in the contact condenser. |
