采用生物质气化再燃技术，在管式流动试验台上对上吸式生物质气化炉产生的含焦油生物质气化气再燃还原 NO 进行实验研究。结果表明，对应一定的生物质气流量，含焦油生物质气还原NO 过程中存在最佳氧量；NO 还原效率随温度升高而增加，但氧气不足时温度过高容易使焦油聚合生成碳黑，导致还原效率下降；通过对比含焦油生物质气与单纯小分子气体还原 NO 的实验趋势，充分体现了焦油的突出作用。在本文实验范围内，含焦油生物质气还原 NO 效率最高达80％，是适合生物质能资源化利用的一种很好的方式。

The technology of biomass gasification for reburning was adopted and the experimental research on NO reduction by reburning of biomass gasification syngas with tar,produced from an updraft biomass gasifier,was carried out on a tubular flow reactor.The experimental results show that there is optimum oxygen content under a certain syngas flow rate.NO reduction efficiency increases with the rise of temperature,but soot generated leads to decline of NO reduction efficiency when oxygen is not enough under higher temperature.The effect of tar on NO reduction can be fully reflected by comparing the NO reduction tendency by using syngas with tar and light gases respectively.NO can be reduced efficiently by approximate 80% using the syngas with tar under the test condition,and is a proper way for the resource utilization of biomass.
