The medium pressure cylinder efficiency of the Dongfang Turbine developed unit reaches the world's leading level

At 10:18 on July 22, the No. 1 steam turbine unit of Shaanxi Shenhua Fuping Thermoelectric 2×350MW newly built project developed by Oriental Turbine was successfully completed in 168 hours of full load. The shaft vibration of each shingle of the turbine was less than 50 microns and the shingle vibration was less than 15 microns. All parameters were good, the flow efficiency of each cylinder was excellent, the environmental protection parameters were better than the design value and lower than the national ultra-low emission standards, especially the efficiency of the medium-pressure cylinder was as high as 95.2%, reaching the world's leading level.

In recent years, Oriental Turbine has developed a large number of high-efficiency models represented by the Fuping project, and its economic indicators have reached the international advanced level, especially the unit's medium-pressure cylinder efficiency is stable at more than 94%, reaching the world's leading level. Oriental Turbine has always adhered to independent innovation, insisted on the green mountains and did not relax, and constantly overcome difficulties, and has made a series of new breakthroughs in practice. By innovating design concepts and improving one's own design capabilities, the economic level of the unit has made significant progress. Through the past five years of hard work, Oriental Turbine has achieved a breakthrough in the core technology of the turbine, completed the evolution of the fourth generation of flow technology, and created and applied a large number of advanced technologies such as suction surface layer control and separation technology, new controllable and reliable steam seals, and runners, which has spawned a large number of high-efficiency units represented by the Fuping project, with the efficiency of medium-pressure cylinders reaching the world's leading level. The breakthrough in the cylinder efficiency indicators of the Fuping project in Shaanxi is a major achievement of the advanced circulation technology of Oriental Turbine and has a milestone landmark significance in the journey of independent innovation of Oriental Electric.

For a long time, Oriental Turbine has been constantly pursuing and climbing the top of technology, and is determined to catch up with world-class enterprises. Through continuous learning and improvement and persistent independent innovation, Oriental Turbine has achieved a transformation from "from follower to leader" in circulation technology, forming an efficient technical system with oriental characteristics. Under the call of the new era and new journey, Oriental scientific and technological workers do not forget their original aspirations and keep their mission in mind, and swear to be dreamers and strive to be runners. By insisting on independent research and development and independent innovation, they will create high-quality steam turbine units with good quality and excellent economicality, and use excellent technological innovation results to promote Oriental Electric to achieve high-quality development in all aspects.
