摘　　要：简述了生物质再燃技术的原理与应用现状,包括直接再燃和气化再燃,还提出将生物质热解多联产技术应用到再燃技术上。生物质用于燃煤锅炉再燃,既可以合理利用生物质,又能有效降低燃煤锅炉的NOx排放,理论减排率可达40%~90%,具有广阔的推广和应用前景。The basic theory of biomass re-burning to reduce NOxemission and domestic industrial application status are discussed in this article, including re-burning with biomass directly and biomass pyrolysis gas. It also suggests to combine pyrolysis polygeneration with re-burning technology and to conduct further test on advanced re-burning. The biomass re-burning technology is capable of consuming biomass in large quantity and reducing NOx emission from coal-firing boiler at a rate from 40% to 90% depending on blend ratio and reaction control. Such capability on emission reduction demonstrates a potential to its economic and application utilization.
