摘　　要：本文探讨了利用电炉炼钢粉尘进行型煤燃烧固硫和烟道气脱硫的可能性，实验测定和理论计算了典型的电炉粉尘的硫容量约为5．5mmol／g；当其作为型煤固硫添加剂时，固硫效果显著；当其作为烟道气脱硫剂时，脱硫率可达95％以上，反应活性很高。进一步加工，有望发展为固定床用脱硫剂，达到以废治废的目的。The possibility of utilizing EAF dust as sul-fur sorbent in coal combustion was investigated. The sulfur capacity of the typical EAF dust is about 5. 5 mmol/g. As the additive of briquette, it can obviously reduce the emis-sion of SO_x from the combustor. As the sulfur sorbent for flue gas desulfurization, the sulfur removal was over 95%.It is promising to process EAF dust to sulfur sorbent for flue gas desulfurization industrially.
