Reaction behavior of SO₂ in the sintering process with flue gas recirculation [PDF]

Journal of the Air & Waste Management Association, 2016
The primary goal of this paper is to reveal the reaction behavior of SO2 in the sinter zone, combustion zone, drying-preheating zone, and over-wet zone during flue gas recirculation (FGR) technique. The results showed that SO2 retention in the sinter zone was associated with free-CaO in the form of CaSO3/CaSO4, and the SO2 adsorption reached a maximum ...
