Utility Using Indirect Dry Cooling Tower

A coal-fired electric power plant in China has ordered an indirect dry-cooling tower to reduce water consumption and improve energy efficiency.
The Huaneng Shaanxi Qinling Power Generation Co. Ltd. has awarded a $36 million contract to the Thermal Equipment and Services segment of SPX Corp., Charlotte, to design and supply the system. The 2 x 660 MW utility plant in Huayin City, Luofu County, Shaanxi province, has an early 2011 operational date.
SPX Cooling Technologies’ indirect dry cooling tower product with its Mega Delta technology utilizes a traditional steam surface or jet condenser and a circulating water system to transfer the waste heat to natural draft concrete cooling towers using air-cooled heat exchanger bundles. This type of system is an attractive option for large plants located in arid environments or in areas subject to water-use restrictions, according to the SPX.
China, in particular, has seen a strong demand for dry cooling technology, because its power generation market remains robust, and water conservation efforts and policies are top of mind, SPX says.
“The Mega Delta technology is a highly efficient solution and very effective in arid conditions,” says Drew Ladau, SPX segment president. “We view China, India and other parts of Southeast Asia, as well as Africa, as ideal markets for these products today.”
As the unit size of power plants continues to grow, modern plants require higher cooling performance, which in turn means larger cooling surfaces and tower sizes, SPX says.
SPX’s Thermal Equipment and Services segment provides wet, dry and hybrid cooling towers, heat exchangers, air and flue-gas systems, and filter systems.
