摘　　要：脱硫型水煤浆的固硫剂主要是钙基固硫剂,其固硫产物在高温下会分解,从而降低燃烧固硫效率。通过研究了氧化铁和氧化钛对水煤浆燃烧固硫的促进作用,发现氧化铁和氧化钛对不同煤种制备的脱硫型水煤浆固硫效果的影响是不同的,但同时添加这两种固硫助剂则可以较大幅度地提高水煤浆的固硫率。The sulfur catcher of the desulfurized coal water mixture mainly is the calcium base sulfur catcher.The caught products will be resolved under the high temperature and then the SO_2 will be released.Therefore the sulfur catching efficiency in combustion will be reduced.The paper studied the accelerative function of ferric oxide and titanium oxide to catch sulfur during the combustion of coal water mixture.The study showed that the sulfur catcher made of ferric oxide and titanium oxide will have different influences by the desulfurized coal water mixtures made of different coal.But once the two materials jointly used for the sulfur catcher,the sulfur catch rate of the coal water mixture would be highly improved.
