After addinglimestoneintocirculating fluidized bed boiler,high temperature solid reaction occurs in two steps: decomposition and burning sulfur salting reaction, the reaction of the twodesulfurization.Wet desulfurization:

direct desulfurization of limestones under oxy circulating

Dec 01, 2019· We compared the directdesulfurizationbehavior of four different domesticlimestonesamples (CaO fraction 40–55%, average particle size 37.5 μm) using a thermogravimetric analyzer (TGA) for experiments conducted under oxy-circulating fluidized bed(CFB) combustion conditions (temperature 600–850 °C, CO 2 60–95%). In addition, morphological variations of the limestones were …
