      Eco-friendly coal-fired technology for stackless power

      Apr 17, 2020 · Coal-fired power plants in Korea are one of the main sources of air pollutants, CO2 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.

      Technical advice on boiler combustion control

      Stack loss generally ranges from as much as 30 percent for a green-wood-fired boiler, to 18 percent for a typical natural-gas-fired boiler, to 12 percent for an oil-fired boiler, to as low as 9 percent for a coal-fired boiler. It must be pointed out that the stack-loss range is wide for any given fuel.
