Coal-fired power plants

KEPCO E&C possesses globally competitive design technology for 500 MW, 800 MW, and 1000 MW coal-fired power plants, having successfully designed 53 units of coal-fired power plants in Korea.

In particular, based on our experience in designing 500 MW and 800 MW coal-fired power plants, we have developed a 1000 MW next-generation coal-fired power plant design and are now applying it as a core model for subsequent coal-fired power plants, starting with the Dangjin Coal-fired Power Plant Units 9 and 10 in 2007.

In addition, to minimize the emissions of harmful substances such as carbon dioxide, cutting-edge environmental facilities that exceed international environmental regulation standards (e.g., greenhouse gas reductions) have been integrated into the design, including top-tier desulfurization/denitrification facilities, electrostatic precipitators, and wastewater treatment facilities. The emissions of nitrogen oxides (NOx) and dust was reduced by more than 70% by incorporating denitrification facilities and electrostatic precipitators into the design, and desulfurization facilities reduced sulfur oxides (SOx) by up to 95%. Thus, the 1000MW coal-fired power plant, equipped with nuclear-level power generation capacity and cutting-edge environmental facilities, is recognized for opening a renaissance of coal-fired power generation.

Power generation efficiency 41.1% 43.54% 45% (target)
Key features
  • High-efficiency operation over the full load range
  • The startup time is shortened and the cyclic operation function is enhanced by installing high-pressure/low-pressure bypass valves
  • Eco-friendly design with the installation of the electrostatic precipitators and high flue stacks
  • All coal ash generated during the operation of power plants can be recycled
  • All by-products (gypsum) generated from desulfurization facilities are sold as raw materials for gypsum boards
  • No wastewater is discharged externally as water is recycled for desulfurization facilities
  • The world's first 50-inch LSB(Last Stage Blade) was applied to improve economic viability
  • Nuclear-level power generation capacity
  • Dust emissions reduced by more than 70% with the installation of cutting-edge environmental facilities
