Wuhan Donghai Coiled-Tube Heat Exchanger: Fueling Core Momentum for China's New Energy Storage Peak-Shaving Projects

Release time：2025-06-05

Recently, China’s energy sector marked a milestone event as the nation’s first "20 MWh advanced packed-bed thermal energy storage system" auxiliary peak-shaving project was successfully put into operation at Huadian Shanxi Shuozhou Thermal Power Branch Company! This innovative project directly addresses the industry’s longstanding challenge of insufficient flexibility in coal-fired power units, breaking through the limitations of traditional power generation and heating models—and paving the way for a significant technological breakthrough in the flexible transformation of coal-fired plants.

The core value of this project lies in significantly enhancing the economic efficiency and operational effectiveness of thermal power plant peak-shaving through a novel heat-storage system. During periods of low electricity demand, the system efficiently stores excess thermal energy; when demand surges, the stored heat is swiftly released—either to maintain stable heating supply or converted directly into electricity. This approach not only optimizes energy-use efficiency but also dramatically strengthens the grid’s ability to withstand fluctuations in load, boosting its overall resilience.

In this groundbreaking project, the high-performance coiled-tube heat exchanger—a critical "energy conversion hub" for thermal energy storage and release—has been meticulously crafted by Wuhan Donghai Petrochemical Heavy Equipment Co., Ltd. (Wuhan Donghai). Renowned for its compact design, exceptional pressure resistance, superior heat transfer efficiency, and minimal thermal stress, the efficient coiled-tube heat exchanger serves as the cornerstone ensuring reliable and stable operation in large-scale thermal energy storage systems. Meeting the project's stringent technical demands, Wuhan Donghai leveraged its deep-rooted expertise and cutting-edge manufacturing capabilities to successfully deliver the key equipment tailored to meet complex operational conditions, laying a robust foundation for the system's overall reliability and advanced performance.

Wuhan Donghai continues to deepen its expertise in the high-end coiled-tube heat exchanger sector, once again proving its capabilities through its involvement in a national-level demonstration project. This time, the company successfully supported the commissioning of China’s first advanced energy-storage peaking project, highlighting Wuhan Donghai’s technological strength in advancing flexible upgrades for thermal power plants and driving the clean energy transition. Moreover, it underscores the company’s proactive commitment to aligning with the nation’s energy strategy, as well as its dedication to leveraging core equipment in building a new-generation power system.

From the traditional petrochemical sector to the cutting-edge energy revolution, Wuhan Donghai has consistently driven innovation and built its foundation on reliability. The successful application of the coiled-tube heat exchanger in this national-level demonstration project marks a significant breakthrough for the company in the critical area of equipment for energy transition. Moving forward, Wuhan Donghai will continue to deepen its expertise in core heat exchange technologies, contributing both wisdom and strength to build a more efficient, cleaner, and flexible modern energy system—and helping China steadily advance on its transformative journey toward a sustainable energy future.
