摘　　要：通过正交试验研究固硫剂品种、粒度、钙硫比 (固硫剂用量 )、固硫温度、粘结剂、原煤粒度、固硫助剂对型煤固硫效果影响。实验发现 :钙硫比和固硫剂品种是影响型煤固硫效果最显著的因素 ;CaO、CaCO3、Ca(OH) 2 3种钙基固硫剂中Ca(OH ) 2 的效果最好 ;钙硫比越大 ,固硫剂颗粒越小 ,固硫效果越好 ;钙基固硫剂最佳固硫温度是 80 0～ 10 0 0℃ ;不同粒级原煤颗粒的型煤固硫效果不同 ;MS粘结剂是理想的固硫型煤粘结剂。The effect of desulfurizer variety and particle size, Ca/S ratio, combustion temperature, binder, raw coal particle size, additives on the briquettes capturing sulfur ability are studied through orthogonal experimental method. It was found that the Ca/S ratio and desulfurizer variety are the most important factors to briquettes capturing sulfur efficiency. The capturing sulfur efficiency of Ca(OH) 2 is highest than the others among the CaO, CaCO 3 and Ca(OH) 2. Higher capturing sulfur efficiency can be gained if higher Ca/S ratio and fine particle size desulfurizer are used. Optimum capturing sulfur temperature is 800～1000 ℃ for calcium based desulfurizer. The capturing sulfur efficiency is different when raw coal particle size is different. MS binder is suitable for capturing sulfur briquette.
