摘　　要：详述了在福建地区首次采用低倍率飞灰循环底饲回燃技术改造一台 1 0 t/ h鼓泡流化床锅炉的情况。对燃用福建地区低挥发份无烟煤流化床锅炉的设计和改造具有参考价值。In order to increase boiler output and utilize local coal more efficiently,a 10 t/h BFB boiler burning Fujian anthracite was retrofitted with several special techniques,in terms of underbed feeding of recycling fly ash,vortexing secondary air injection,continuous bottom ash removal and adding immersed tube surface. The boiler performances before and after the retrofitting were measured and compared.The retrofitting was completely successful.The technique used and experiences obtained in the retrofitting can be widely applied in industrial BFB boilers.
