This results in calcium compounds enrichment in the end product, which is highly dependent upon the used desulfurization technology (Twardowska, 1999b). In the dry method, limestone or pulverized limestone is injected into the boiler furnace, where the calcium carbonate decomposes thermally to form calcium oxide and carbon dioxide.
