Good news! Warm congratulations to Xinjiang Huadian Hami 2×1 million kW coal power project - the world's largest and highest height hyperbolic intercooling tower successfully completed the top

Xinjiang Huadian Hami 2×1 million kilowatt coal power project is located in the Gobi shoal area at the northern foot of Tianshan Mountain in Xinjiang. Our company has built two intercooling towers, 1# and 2#. The project is a super-large hyperbolic steel intercooling tower, which is the first application in millions of thermal power units and is currently the world's largest and highest hyperbolic steel intercooling tower. Compared with the concrete tower, the weight of the cold tower between steel structures can be reduced by about 90%, the construction period is shortened by about 6 months, and the steel structure is 100% recyclable. The main structure of the cooling tower adopts the bidirectional oblique space lattice shell structure, and the nodes are welded balls and intersecting nodes. The total height of the structure is 210 meters, the thickness of the tower is 3 meters, and the diameter of the center line of the outer support is 147 meters. The tower is divided into 21 floors from bottom to top, the third floor is provided with a broadening platform, and the sixth, ninth, 12th, 15th, 18th and 21st floors are provided with 6 reinforcing rings. With 32 triangular truss units on each floor and a total weight of 8,500 tons of single pylons and purlins, the two towers were simultaneously crowned on September 6, 2024.

In the Gobi beach area at the northern foot of Tianshan Mountain in Xinjiang, the gale weather of six or above reaches more than 200 days every year. Such climate conditions have caused considerable difficulties for the construction. Moreover, the installation volume of the project is large, the height is high, the welding is difficult, and the space positioning is complicated during installation and other multiple challenges. To meet the difficulties, careful organization, scientific management, fine construction, with high standards, strict requirements, pay close attention to safety management as the goal, the construction actively use the whole process of electronic video surveillance equipment for safety control, to ensure that there is no dead corner of safety control, and jointly with the general contractor, supervision unit carefully do the preparation of work instructions, audit work. And to participate in the construction personnel before the operation of the disclosure, clear personnel responsibilities, to ensure the smooth implementation of the project.

The company has carefully set up a strong and experienced engineering project leadership team. The team members comprehensively and deeply carried out comprehensive management of a series of work such as technical support, processing process, transportation arrangement, installation and deployment, as well as crucial safety guarantee of the project. Through scientific and reasonable overall planning, rigorous and meticulous process control, and timely and effective problem solving, the 1# intercooling tower was created 38 days ahead of the contract period. The new speed of the 2# intercooling tower is 68 days ahead of the contract period, and the successful completion of the intercooling tower topping has laid a solid foundation for promoting the early completion, early operation and early power generation of the project, which has milestone significance in the project implementation process.

Xinjiang Huadian Hami 2x1 million kilowatt coal power project as the national "14th Five-Year" development plan determined the key energy projects. The project uses domestic efficient ultra-supercritical indirect air cooling million units, and after the completion of the power plant, it will ensure the safe operation of ±800 kV UHV DC transmission system and reliable grid-connected consumption of new energy, providing a powerful power supply guarantee for power transmission in Xinjiang. The project is another dazzling benchmark project of Tongyu Spatial Structure Co., LTD., is the pride of all Tongyu people!

Under the national development strategy of air pollution prevention and energy conservation and emission reduction, the intercooling tower has the characteristics of energy saving, water saving and environmental protection, and has become the trend of the thermal power industry in the future. From design to construction of steel structure cold tower, the company's technical team has always grasped the pulse of the design and construction technology development of steel structure cold tower, carried out systematic research for steel structure cold tower, conquered one technical problem after another, and achieved phased results. This project reflects the company's excellent ability in steel structure manufacturing, construction management, team cooperation and other aspects, laying a solid foundation for undertaking more large-scale and complex engineering projects in the future. Xuzhou Tongyu will, as always, uphold the concept of "carrying forward the spirit of artisans and casting an iron army team", create high-quality projects for China's power construction, and contribute to achieving the goal of "carbon neutrality".
