Air cooling system

for the energy sectorcustom-madeair-cooled

Product overview
Shuangliang conducts long-term R&D and experimental validation for steel-structure cooling towers, including wind-tunnel tests (rigid-model pressure and aeroelastic-model vibration), cladding anti-wind tests and on-site verification. In partnership with Wuhan University of Technology, SHUANGLIANG GROUP established a dry-cooling experimental base applying Array Grating fiber-optic sensing and Beidou positioning for temperature-field monitoring and displacement measurement to enable intelligent control of steel-structure towers.

Technical capability
Shuangliang has completed extensive wind-tunnel campaigns and anti-wind assessments. In May 2012 the company completed China’s first wind-tunnel test of an air-cooled steel tower, supporting engineering design and achieving performance comparable to international advanced standards.

Six advantages

• 01 Highly cost effective: For equivalent scale and investment, cooling performance improves by about 5%. Rising material costs and mining limits increase the cost advantage of steel-structure towers.
• 02 Digital and intelligent: Array Grating fiber sensing enables fine temperature-field control of the indirect cooling system, reducing winter back pressure by ~3 KPa and saving ~4.5 g/kWh of coal consumption.
• 03 Short construction period, early production and revenue: Factory prefabrication and on-site modular assembly with unit hoisting shorten construction to roughly one third of traditional concrete towers; for a 2×660 MW plant this can reduce schedule by ~6 months (example revenue impact CNY198 million).
• 04 Circular economy and environmental compliance: Steel-structure towers avoid concrete and reduce raw-material consumption (sand/stone), align with energy-conservation and prefabrication policies, and offer high recovery/residual value for steel and aluminum. Replacing concrete towers in a 2×660 MW plant can cut CO2 by ~36,000 tons.
• 05 Construction safety: High-altitude labor for steel-structure assembly is approximately one tenth of that required for concrete towers, lowering safety risks.
• 06 Design flexibility and operating savings: Small-diameter 6-row pipes with double-sector layout remove inlet-height constraints, optimize system hydraulic design, reduce indirect-system water resistance and deliver running electricity charge savings >25%.

Typical cases
