Limestone-gypsum wet flue gas desulfurization（FGD） technology takes limestone as raw material to absorb SO2 from flue gas and obtain gypsum.While controlling SO2 emission,the treatment and comprehensive utilization of FGD gypsum are also very important.FGD gypsum was used as raw material to analyze the composition and carried out by heat treatment,and the effect of heat treatment process on the physical properties of gypsum was characterized.The heat treated gypsum was used in the manufacture of gypsum mould,and the anode support of solid oxide fuel cell was finally prepared.The fuel cell test results showed that FGD gypsum can be used for the preparation of tubular solid oxide fuel cells.
Key words： FGD gypsum; heat treatment; slip casting; solid oxide fuel cell
