May Chinese manufacturing become better and stronger.

Shanxi Blower’s distributed energy system solutions help YanNeng Group to utilize low-grade coal in a clean and efficient manner. Low-grade coal is a type of coal. It refers to coal that produces a long flame and smoke when burned, indicating a lower degree of coalification. Based on volatile matter content, thickness of the gum layer, or technical properties, they can be classified into long-flame coal, gas coal, fat coal, coking coal, lean coal, and thin coal, among others. It is used as a raw material in coking, refining, gasification, low-temperature carbonization, and the chemical industry, and can also be used directly as fuel. Low-grade coal accounts for 56% of China’s total coal reserves ； China’s annual coal consumption is around 4 billion tons, of which low-grade coal accounts for approximately 53%. If all the low-grade coal consumed each year were utilized in a clean and efficient manner, it would be possible to obtain 137 million tons of fuel oil, 81 million tons of LNG, and 1.72 billion tons of semi-coke (clean coal). This is crucial for ensuring energy security, promoting energy conservation and environmental protection, and improving the efficiency of coal utilization. The selective and clean utilization of low-rank coal is also a development direction for the coal chemical industry that receives strong policy support.

In March 2015, the gas turbine-driven centrifugal pipeline compression units developed and produced by Shaanxi Gas Turbine won the bid for the \"Jingbian to Xi’an Natural Gas Pipeline Line 3 Project (Phase II)\\". It is an important part of the “Gasification of Shaanxi” project, and it is also a key initiative aimed at reducing coal-fired emissions, combating pollution and haze, and improving people’s livelihoods. Through careful design and precision manufacturing, SHANGU has achieved significant technical breakthroughs in the research, development, and manufacturing of large-scale centrifugal compressors in China, as evidenced by the gas-fired pipeline compression units it provided for the Jingxi Third Front natural gas transmission project.

The natural gas long-distance pipeline compressors newly developed by Shaanxi Gas Turbine Power have passed the **evaluation. Gas Online, June 13, 2018 – The EB80 model compressor units for natural gas long-distance pipelines developed by Xi’an Shaanxi Gas Turbine Power Co., Ltd. (referred to as Shaanxi Gas Turbine Power) have undergone **scientific and technical achievement evaluation organized by the China Petroleum and Chemical Industry Federation. The evaluation team unanimously agreed that the overall performance indicators of this unit are at the leading level in China, with key technical parameters such as compressor efficiency and operating range having reached the international advanced level. This represents the independent development of large-scale pipeline compressor technology and its subsequent manufacturing in our country. It not only signifies that Shangdu Power has broken through the foreign monopoly on the core technologies related to compressors for natural gas mainline and branch pipelines, thereby acquiring the capabilities to design, manufacture, test, and service such compressor units, but it also lays a solid foundation for advancing the localization of key equipment used in natural gas pipeline transportation in our country as well as for technological progress in this field. As a clean energy source, natural gas plays an important role in global energy consumption. It is understood that in 2017, China’s natural gas consumption was 237.3 billion cubic meters, representing a year-on-year increase of 15.3%. As one of the main means of transporting crude oil, refined products, and natural gas, oil and gas transmission pipelines play an important role in national infrastructure development. By the end of 2017, the total length of oil and gas pipelines in operation in China was approximately 133,100 kilometers. It is estimated that by the end of the 13th Five-Year Plan period, the total length of China’s long-distance oil and gas pipelines will exceed 160,000 kilometers. Experts explain that China’s natural gas mainline and branch line projects utilize high-pressure, large-diameter long-distance gas transmission pipelines. Generally, a compression station equipped with multiple high-power compressors is needed every 100 to 200 kilometers; through multi-stage pressure enhancement by these compressors, the frictional resistance during transmission is overcome, enabling the long-distance transport of natural gas. Therefore, the compression unit is regarded as the “heart” of natural gas long-distance pipelines. Leveraging its 50 years of technical expertise and comprehensive capabilities in the field of energy conversion equipment, Shaanxi Gas Turbine Power conducted thorough research and analysis on pneumatic parameters, structural features, and control technologies, based on the operational experience gained from various compressors along the West-East Gas Pipeline projects.
