Flue gas desulfurization
Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators. The most common types of FGD contact the flue gases with an alkaline sorbent such as lime or limestone. As sulfur dioxide is responsibl...
متن کاملMicrostructure contradistinction for indirect/direct desulfurization product layer of limestone particle in coal-fired flue gas
The micro morphology of limestone sorbent is a key for improving the SO2 removal efficiency in the coal-fired power plant. The tube furnace system was built for imitating the indirect desulfurization reaction in traditional boiler atmosphere (65%N2, 15%CO2, 4.7%O2, 15%H2O, 0.3%SO2) and the direct desulfurization reaction in oxygen-fired atmosphere (80%CO2, 4.7%O2, 15%H2O, 0.3%SO2). The reacted ...

Základné vlastnosti sadrovca pre odsírenie spalín Several hundred thousand of FGD gypsum is produced annually at the Matra Power Plant (Hungary) as a byproduct of generating electricity and protecting the environment. Chemical and mechanical characteristics of this material were studied of the Department of Mining and Geotechnical Engineering, University of Miskolc (Hungary). The material in qu...
متن کاملInvestigation on Mercury Reemission from Limestone-Gypsum Wet Flue Gas Desulfurization Slurry
Secondary atmospheric pollutions may result from wet flue gas desulfurization (WFGD) systems caused by the reduction of Hg(2+) to Hg(0) and lead to a damping of the cobenefit mercury removal efficiency by WFGD systems. The experiment on Hg(0) reemission from limestone-gypsum WFGD slurry was carried out by changing the operating conditions such as the pH, temperature, Cl(-) concentrations, and o...
