基于赤铁矿的生物质化学链燃烧过程中氮氧化物的释放特性
, PP. 490-498
Keywords: 化学链燃烧,生物质,赤铁矿,氮氧化物
Abstract:
？在单批次进料固定床上,基于赤铁矿载氧体,研究了还原反应阶段反应温度和水蒸气量对谷壳的氮氧化物释放特性的影响。研究表明,碳转化率随反应温度升高而增加,但随水蒸气量呈先增加后下降,并在水蒸气量为1.0g/min时达到最大值。在实验条件下,还原阶段未检测到no2。随着反应温度由750℃升高到900℃,no的生成率增加,而n2o的生成率先增加后降低,在850℃时达到最大值。水蒸气量由0.5g/min升高到2.0g/min,n2o和no的生成率均增加,且no增加速率高于n2o。在反应后的载氧体中,检测到kalsi3o8存在,表明载氧体与生物质中的k元素发生反应。
