At present, most of the dry and semi-dry flue gas desulfurization (FGD) residues are simply stored and have become an obstacle to the popularization of the FGD technologies. The utilization of these residues needs to be solved urgently. Based on sufficient studies of the composition properties of the FGD residues, a completely new utilization method was put forward to produce sulfoaluminate cement in this paper, and experiments were carried out. In the experiments, the residues and some other materials were utilized to prepare raw meals according to appropriate element matching proportion. It was proved that, on a certain calcining condition, the raw materials could be converted to cement clinkers with mineral compositions being calcium sulfoaluminate (Ca4Al6O12SO4) and dicalcium silicate (Ca2SiO4), and with excellent mechanical strength properties. This utilization method, which can consume massive these residues, may have a wide prospect of application.
