  • Waste Expo – October 2014

    1/2/1999 · The flue gas leaves the furnace at 850–870 C, and waste heat is recovered in a boiler and air preheater. The flue gas cleaning system includes electrostatic precipitators and wet scrubbing. About 45 t/day of ash is generated and with the help of the wet flue gas desulphurization (FGD) unit, SO 2 emissions are reduced from 2500 mg/m 3 to less than 30 mg/m 3 in the flue gas leaving.Learn More

    There are three forms of Mercury present in coal-burning power plant systems: particulate mercury, oxidized mercury (Hg2+), and elemental mercury (Hg). Only particulate and oxidized mercury are captured by existing Air Pollution Control Devices (APCDs). One method for mercury control is Activated Carbon Injection (ACI) and particulate control.Learn More

    In a waste heat boiler, the heat from the gas is recovered as saturated or super-heated steam. The boiler must be designed to operate reliably with acidic gases, and often sticky dust as well. For some applications, the effort required for energy recovery does not justify the use of a boiler.Learn More
