In 2009, under the auspices of the National Energy Administration, 703 Harbin Steam Turbine Co., Ltd. and Shenyang Blower Group entered into the "Development Agreement for a 30 MW Combustion Drive Compressor Unit for Localization of Key Equipment for Long-distance Natural Gas Transmission Pipelines" with PetroChina West-East Gas Pipeline Company. Together with the "20 MW Electric Drive Compressor Unit" and the "High Pressure Large Diameter All-welded Ball Valve", it became the most important localization project for the key equipment for the three long-distance natural gas pipelines at that time.
In the initial stage of development, the development team integrated the imported gas turbines with domestic compressors and auxiliary systems. The localization rate reached 52% to form the prototype “product 1â€; in the second stage, domestic gas turbines were integrated with domestic compressors and auxiliary systems to form the Prototype "Product 2"; eventually formed a 30 MW-class combustion-driven compressor unit with a localization rate of over 96%. During the development of the project, key breakthroughs have been made in gas turbine high-speed power turbines, low-emission combustion chambers, control systems, belt fuels, and integrated device design technologies, all reaching internationally advanced levels.
The successful operation of this unit will bring more than 10 billion yuan in output value. Only China's West-East Gas Pipeline project needs 140 sets of equipment, with an output value of up to 14 billion yuan.
The China Shipbuilding Industry 703 Institute, as the main power R&D and supply unit for large and medium-sized naval vessels, has successfully developed a 30 MW gas turbine driven compressor unit, which is a model for innovation in China’s “military transfer†product, and will bring powerful Small and medium-sized power industry groups have jointly promoted the development of China's military industry.
China Instrument Network Instrument Development According to China Shipbuilding Industry Corporation, the Group’s 703 first domestically-produced 30 MW gas-fired compressor unit, the No. 1 machine at Yandun Station on the 3rd line, successfully developed over the past 7 years, on September 21st. The 220-hour operation test is completed at the smoke pier gas station on the 3rd line of the West-East Gas Pipeline in China and will soon be put into operation. This means that the history of dependence on imports of China's natural gas long-distance pipeline burning-driven compressors is about to end. The gas turbine-driven compressor unit can be said to be the "heart" of long-distance natural gas pipelines, including gas turbine installations, centrifugal compressors, unit monitoring systems and electrical systems. Due to the complex multi-disciplinary, multi-domain, multi-system rotating machinery, it is extremely difficult to design and manufacture. It is the highest-end product in the field of energy and power equipment. The cost per unit is nearly 100 million yuan.
