以生物质气化气作为再燃燃料,在小型流化床反应器内进行了N_2O脱除的实验研究.研究了生物质气化气投入位置、料层高度、再燃燃料比、烟气含氧量和反应温度对N_2O排放的影响. 结果表明,距布风板200mm的B喷口较离布风板较近的A喷口(距布风板100mm)对应的N_2O转化率高;反应温度为850℃、按照N_2O/N_2配置模拟烟气的情况下,B口喷入生物质气量为1%,床料CaO高度为10mm时N_2O接近完全分解;反应温度为850℃,床层高度大于20mm时,从B口喷入大于0.4%比例的生物质气对应N_2O分解率高于95%.

Experimental research on biomass derived gas reburning for N_2O removal was carried out in a small scale fluidized bed combustor. The effects of reburning position, the height of material bed, the rate of reburning fuel, the initial oxygen content of flue gas and reaction temperature on N_2O emission were investigated. The results show that the decomposition rate of N_2O with the reburning of biomass derived gas at nozzle B (200mm over the air distributor) is hiher than that at nozzle A (100mm higher than air distributor). When 1% of biomass derived gas with regard to N_2O/N_2 mixture is ejected from nozzle B at 850℃ of bed temperature and 10mm of bed height, N_2O is decomposed nearly completely.
