Apr 17, 2020· Coal-fired power plants in Korea are one of the main sources of air pollutants, CO 2 and the other precursor materials to ultra-fine dust particulates such as nitrogen oxide and sulfur oxide. Therefore, FEPCRC is developing key technologies for eco-friendly coal-fired stackless power generation without emissions in flue gas.
Some plants in the West use wet-lime systems, where the cost of lime delivered to the plant is less than limestone. Some plants firing high-sulfur coal in the Midwest have selected wet sodium-based dual-alkali systems. Dry scrubbing systems have typically been selected at power plants firing low-sulfur coals.
