en.Wedoany.com Reported - The X-columns of the indirect cooling tower No. 1 for the coal-power project at the Ruoqiang New Energy Base in Xinjiang, invested and constructed by China Three Gorges Corporation, were successfully closed recently, marking a phased achievement in the construction of the tower's critical support system. The closure of the X-columns lays the foundation for subsequent shell construction and the completion of the annual construction tasks.
The coal-power project at the Ruoqiang New Energy Base is a core component of the power source project for the fourth "Xinjiang Power Outward Transmission" channel, and also a vital supporting element of the first 10-gigawatt-level "Desert, Gobi, and Barren Land" wind-solar-thermal-storage outward transmission base project in Southern Xinjiang. The project is equipped with six 660-megawatt ultra-supercritical coal-fired generating units, with a total installed capacity of 3.96 million kilowatts, and simultaneously constructs environmental protection facilities such as flue gas desulfurization and denitrification. The indirect cooling tower, as a major individual structure, performs the cooling system function for the generating units.
Designed with a two-units-per-tower configuration, the project plans to build three indirect dry cooling towers, each standing 225 meters tall, with a bottom ring beam diameter of 155.27 meters and a pillar center diameter of 178 meters. They are supported by 56 X-shaped pillars, with each single X-column steel structure weighing 63 tons. These are among the largest indirect cooling towers of their type currently under construction in China.
Project engineer Chen Xiao explained that the X-column components are large in volume and heavy in weight, requiring safety briefings, rigging inspections, and wind speed condition confirmations before hoisting. Immediately after positioning, measurements are rechecked to ensure accurate placement, stable connections, and controllable quality. With the closure of the X-columns for cooling tower No. 1, project construction has further accelerated. Chen Xiao stated that construction in key areas such as the main power building, boilers, chimney, and indirect cooling towers is now advancing on multiple fronts simultaneously, and shell construction will commence next to ensure the completion of the annual construction targets.
