Successful First Attempt at Turbine Run-Up for Qinghai Haixi Liquid Air Energy Storage Project
2025-12-22
At 18:53 on December 21, the turbine run-up for Qinghai Haixi Liquid Air Energy Storage Project was successfully achieved on the first attempt, laying a solid foundation for the smooth progression of subsequent system tests.
The project adopts a domestically pioneered technological approach of "three-stage compression + four-stage expansion" coupled with cryogenic (methanol, propane) chemical media to achieve cold storage and rewarming. It is equipped with a customized 60MW-class medium-temperature, medium-pressure air turbine unit from Harbin Turbine Company. Through multi-stage small enthalpy drop and efficient reaction-type blade axial exhaust design, the turbine efficiency is significantly enhanced. The first-stage inlet parameters of the expansion turbine reach 4.275 MPa and 177.5°C, enabling flexible start-stop and reliable operation, thereby achieving a precise balance between thermodynamic efficiency and safety. To ensure the one-time success of the turbine run-up, the project team established a dedicated task force, innovatively optimized the commissioning management plan, precisely monitored key parameters throughout the process, and strictly implemented various safety and technical safeguard measures. Ultimately, the one-time successful run-up was achieved, with all operating parameters meeting technical specifications, validating the feasibility and reliability of the project’s innovative technical approach.
Moving forward, the project team will continue to adhere to the "High Standards, Strict Requirements, Meticulousness, Practical Implementation" work principle, strengthen technological breakthroughs and quality control, strictly implement safety and environmental targets, seize the momentum to advance subsequent turbine, electrical tests, and full-process commissioning tasks, driving the company’s new energy business to new heights of high-quality development through excellent contract performance.
