Details Introduction
The "chimney-stack integration" technology refers to the method where exhaust gases from thermal power plants are no longer emitted into the atmosphere through chimneys but are instead channeled via ducts to hyperbolic cooling towers. The gases, after desulfurization treatment, are then released at high altitudes through ducts integrated into the cooling towers, combining the exhaust emission system with the tower structure.
Fiber-reinforced plastic (FRP) is chosen for the ducts in chimney-stack integration due to its excellent corrosion resistance and durability, offering a long service life and cost efficiency. With a lifespan of up to 30 years, it aligns well with the lifecycle of a thermal power plant, avoiding economic losses and operational disruptions caused by pipe material replacement, while also saving on anti-corrosion costs. Additionally, the lightweight nature of FRP eliminates the need for support brackets, reducing construction expenses.
The environmental significance of chimney-stack integration is substantial. As a mature technology developed in Germany in the 1980s, it achieves a gas purification rate of up to 97.5% by utilizing cooling towers for exhaust emission. Notably, the ground-level concentration of emitted gases is significantly lower compared to traditional chimney emissions. While chimneys typically release exhaust at around 300 meters, cooling towers disperse gases at 500 meters, thereby expanding the diffusion range and reducing the ground concentration of carbides to below 400 mg/m³.
 The large-diameter chimney-stack integration project at Tianjin Guodian Jinneng Power Plant was designed by Beijing Guodian Huabei Electric Power Engineering Co., Ltd., manufactured by Jizhou Zhongyi Composite Materials Co., Ltd., and installed by the same company. |
