The results showed that addition of barium nitrate to the CaO can enhance the sulfur removal rate of CaO significantly. The X \|ray diffraction spectrum of residual ash of coal added some sulfur fixative expressed that Ba\+\{2+\} can form a compound of Ba\|Al\|Si\|O which encloses the CaSO\-4 to prevent it's decomposition, so Ba\+\{2+\} can improve the action of sulfur fixation of CaO. The combustion character of the original coal and original coal added sulfur fixative was researched with thermal\|gravity analyzer and the results expressed that adding some sulfur fixative to the coal will make the combustion character of coal change little.展开更多

Results showed that the efficiency of sulfur capture of Ca（OH）2 is the highest among these three compounds. When CuO was used with each of CaO, Ca（OH）2 and CaCO3 at the same time, the efficiency of all of them would rise, and that of Ca（OH）2 raise most. The efficiency of sulfur capture of Ca（OH）2 with CuO is 14.4% higher than that without CuO.展开更多
