Summary of research progress on industrial flue gas desulfurization
In-furnace calcium injection desulfurization technology sends limestone powder or lime powder gas into the furnace. Under high temperature conditions, calcium carbonate decomposes to form CaO, and the generated CaO reacts with SO 2 to form calcium sulfate. This method has the characteristics of a low investment, low operating …
