Why does "Beixi No. 1" choose a Western turbine?Russian expert: Russia cannot build this kind of turbine in 2011

[Global Times special reporter Liu Yupeng Renzhong] Russia's Natural Gas Industry Co., Ltd. (Russia) announced on the 25th that the turbines of another Siemens Company at the "Poltova" compressor station will be discontinued, so from July 27th 27th From the beginning of the day, the natural gas supply through the "Beixi-1" natural gas pipeline will not exceed 33 million cubic meters per day, about 20%of the pipeline gas transmission capacity. Earlier, because a turbine sent to Canada was not returned, Russia had reduced the gas transmission volume of the pipeline to 40%. So what key role does a large turbine play in this pipe pipeline? Why does this pipe use a turbine produced in the West?

Russia's "Business News" reported on the 26th that at present, Russia runs a total of 8 gas compressed units (composed of turbines and compressors) at the "Poltova" compressor station. (Based on the production of Luo Luo aircraft engine) and 2 SGT-A35 turbines with smaller power. In normal mode, this machine station should have 6 turbines that are running, 5 of which work and one is in a hot state. The "Beixi-1" natural gas pipeline is the main natural gas pipeline that directly connects Russia and Germany. It is an export of natural gas pipelines from the Baltic Sea to Europe from Russia.

According to the Russian Rambler report on the 26th, Igor Yushkov, an expert in Russian energy, said at least 3 of the eight turbines of this station station need to be repaired, of which one has not been shipped back from Western countries. The normal operation of this pipeline depends on these turbines. In 2011, Russia could not create this turbine when construction was built.

According to reports, the turbine of the Boltova Natural Gas Compressor Station provides the front -end gas supercharged for the underwater section of the Beixi pipeline. The pipeline runs at the bottom of the Baltic sea. The German coast near Germany.

"Voice of Germany" said that because the turbine has long been a major political issue between Russia and Europe and the United States, the task of Russian companies has been designed and built a new high output turbine over the years to replace aging foreign equipment. In 2017, a prototype motorcycle developed by Russia failed in the test. The development of large -scale turbines really requires a lot of funds. Vapor and gas turbine experts at Aachen University of Technology, Germany, said the initial cost will be hundreds of millions of dollars or euros. He added that Russia has a turbine power plant technology. Although it is not the latest, largest or most efficient, it is worth noting whether Russia can develop large -scale turbines based on this technology, or re -developed new large -scale turbines.

In addition to huge R & D costs, developing new, large -scale turbines also requires dense scientific development and long -term trials. Mattias Zerlins, an expert in German Machinery and Equipment Manufacturing Federation, said that today's large gas turbines are one of the most complicated machines, and the technical threshold for entering this market is very high. The global market of large turbines is currently in the hands of four major producers in developed countries.

On the road to developing such turbines, in addition to technical and capital obstacles, there are also commercial risks. Zelinge said that such demand has fallen to about 100 units per year. "Voice of Germany" says that this is why GM and Siemens are trying to try to reduce the work of thousands of jobs in the production department of the turbine. This means that the Russian turbine developer is facing a market with a shrinking and severe production capacity. However, the Russian government does not expect engineers to produce competitive export products. Russia is more concerned about the domestic market. The Russian Ministry of Energy has stated that the demand for powerful turbines is not very high, only 1 to 3 units each year. The annual production of 1 to 3 turbines shows that from an economic point of view, Russia's large amount of funds investing in the development of large gas turbines will be a loss of money.
