循环流化床富氧气化实验研究
, PP. 297-302
Keywords: 循环流化床,煤气化,氧气浓度,当量比
Abstract:
?在循环流化床富氧气化实验台上,通过调节水蒸气流量使气化温度基本稳定在910℃,研究了不同氧气浓度及气化当量比对煤气组分、产气率、冷煤气效率及碳转化率的影响。结果表明,氧气浓度从25%增加至40%时,n2体积分数从48.82%降低至33.83%,h2从21.47%不断增加至27.59%,ch4基本不变;受水蒸气流量影响,氧气浓度高于35%时,co体积分数降低,co2体积分数增加;氧气浓度40%时的煤气热值为空气气化煤气热值的1.84倍,产气率随氧气浓度增加从2.35m3/kg降至2.13m3/kg,冷煤气效率和碳转化率不断增大;当气化当量比从0.20增加至0.29时,n2体积分数先降低后升高,h2体积分数从24.01%增加到25.46%后基本保持不变,co和ch4持续减小,co2不断增加,产气率由1.94m3/kg升高到2.29m3/kg;受水蒸气和气化当量比综合影响,冷煤气效率先增大后减小,碳转化率持续增加。
