Abstract:在沉降炉上研究草本类棉秆、玉米秸、麦秆和木本类梧桐木四种生物质的先进再燃脱硝特性。结果表明,20%再燃比、0.7s停留时间能保证较优的反应工况。在过量空气系数为0.7~0.9、氨氮摩尔比为1.5左右时,棉杆、玉米秸、麦秆以及梧桐木先进再燃在1273K附近取得最高脱硝效率,其值分别为89.11%、88.34%、90.33%和88.28%,比基本再燃提高25%~30%,并且生物质的再燃反应是脱硝的主体,喷氨是对再燃的完善和优化。在1173K~1473K四种生物质的先进再燃可以保持80%以上的脱硝效率。实验过程中加入100×10-6的碱金属、碱土金属添加剂可进一步改良先进再燃脱硝进程。碳酸钠、碳酸钾使脱硝效率提高3%~6%;醋酸钙在1273K~1473K将脱硝率提高4.0%~5.0%,在1073K~1273K作用规律不明显。
