2026-07-02
On May 30, 2026, the waste heat power generation installation project of the Jiaxian Zhonglian Tianguang Cement 4500t/d new dry-process cement clinker production line technical transformation project, undertaken by the Electric Power Engineering Division, reached a significant milestone. On the afternoon of May 30, the steam turbine of the project achieved successful rotor turning on its first attempt. The unit operated smoothly, and all key performance indicators met and even exceeded industry excellence standards. This marks a critical breakthrough in the installation and commissioning of the waste heat power generation system, laying a solid foundation for the subsequent full-unit startup and grid-connected power generation.
The Jiaxian Zhonglian Tianguang Cement technical transformation project is a key local industrial upgrading initiative. Its supporting waste heat power generation system plays an important role in enhancing energy utilization efficiency and reducing the production line's energy consumption. The Electric Power Engineering Division undertook the core construction tasks of this waste heat power generation installation project, with the main scope of work including: boiler body installation, steam turbine and auxiliary equipment installation, and SCR denitrification system installation. Among these, the SCR denitrification system is required to be installed directly above the kiln tail boiler, with the installation elevation ranging from 36 meters to 54.4 meters. This constitutes a typical working condition involving elevated heights, confined spaces, and multi-trade cross-operations, presenting considerable construction difficulties.
Post-turning measured data showed that the vertical vibration of the steam turbine and generator ranged from 0.003mm to 0.008mm, and the horizontal vibration ranged from 0.006mm to 0.011mm. The turbine-generator unit operated with exceptional stability, achieving vibration control at an outstanding level—even better than the industry-recognized excellent standards for turbine units. This result fully demonstrates the Electric Power Engineering Division's meticulous quality control capabilities in key processes such as steam turbine installation, and also validates its comprehensive strength in maintaining high construction quality under multiple adverse working conditions. After the entire waste heat power generation system was started up, it operated stably with excellent parameter performance, earning unanimous praise from both the general contractor and the client. Representatives from the relevant parties stated that achieving first-time successful turbine rotor turning with vibration indicators reaching excellent levels—under conditions of delayed equipment arrival, severely restricted working space, and highly complex cross-construction operations—fully showcases the technical expertise and management capabilities of the construction team.
