reply Hai Shenneng Power Technology Co., Ltd. presented the world's first secondary reheat technology

At the 2nd Chain Expo, a number of top technological exhibits representing the development direction of new quality productivity appeared on the scene. Shanghai Shenneng Power Science & Technology Co., Ltd. brought three typical advanced coal power innovative technology application results, among which the application results of “turbine high and low position split-axis arrangement secondary reheat technology” attracted much attention, attracting delegations from the local government, National Energy Group, China Resources Power, Huadian Power Group, Shandong Energy Group, exhibitors, and special guests of China Energy Research Institute and many important guests and leaders to the booth to study and exchange information about its clean, efficient and flexible integrated technology in coal power. It attracted many important guests and leaders, such as delegations from local government, National Energy Group, China Resources Power, Huadian Group, Shandong Energy Group, exhibitors and special guests of China Energy Research Institute, to investigate and exchange ideas at the booth, to learn about its leadership and innovation in the field of clean, efficient and flexible application of coal power, and to feel its unlimited vitality in modernizing, strengthening and toughening the chain in the field of coal power.The reporter learned that Shanghai Shenneng Power Science and Technology Co., Ltd. is a holding subsidiary of Shenneng Co., Ltd. and the supporting unit of Shanghai Clean Coal Power Engineering and Technology Research Center, which is mainly engaged in providing thermal power units with customized solutions for energy saving, carbon reduction, deep peak adjustment and other comprehensive upgrading and transformation, or integrated optimization of newly-built units and loading of special technologies.The “Turbine High-Low Split Shaft Arrangement Secondary Reheat Technology” demonstrated in the on-site technical video was invented by Prof. Feng Weizhong, General Manager of Shanghai Shenneng Electric Power Technology Company Limited, and is the first of its kind in the world with independent intellectual property rights. This technology can significantly shorten the high-temperature and high-pressure steam pipeline between the boiler and the steam engine, releasing the space for the development of high-parameter secondary reheat and further improving the efficiency of secondary reheat technology.The technology has been applied in the national demonstration project-Shenergy Anhui Pingshan Power Plant Phase II to build a new 1,350MW secondary reheat unit with high and low level split shaft arrangement, which has been formally put into operation in April 2022, and its standard coal consumption for power supply at rated operating conditions has historically broken the 260g/kWh and 250g/kWh marks in a row to reach 249.31g/kWh, dramatically setting a new record for the standard coal consumption for power supply at rated operating conditions at 260g/kWh and 250g/kWh, which is the highest among all the coal consumption units in China. Kilowatt-hour, significantly refreshing the world record, for the current domestic and foreign coal power units of the optimal level, set up a new benchmark for international coal power.Shanghai Shenneng Power Science & Technology Co., Ltd. also displayed advanced projects such as “China Resources Xuzhou 320MW high-temperature subcritical unit comprehensive upgrading project” and “China Resources Caofeidian new 2×1050MW ultra-supercritical unit technical consultation and energy saving and emission reduction technology integration project”. Caofeidian new 2×1050MW ultra-supercritical unit technical consulting and energy saving and emission reduction technology integration project” and other advanced coal power innovation and technology application results, and in-depth exchanges with the supply chain upstream and downstream partners.
