循环流化床富氧气化实验研究

摘要: 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2.35 m3/kg降至2.13 m3/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1.94 m3/kg升高到2.29 m3/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。
