摘　　要：采用飞灰循环底饲回燃技术改造西南合成制药总厂热电分厂、天府矿务局磨心坡发电厂2台东方DG35/3.82-7型低倍率循环流化床锅炉。改造后运行结果表明,锅炉可长期、稳定运行,尾部飞灰可燃物含量大幅度降低,锅炉蒸发量提高20％左右,节煤效果明显。为燃用贫煤、无烟煤和煤矸石等劣质燃料且锅炉炉膛高度较低的电站技改,提供了一种切实可行的方法。Two DG35/3.82-7 boilers have been retrofitted to circulating fluidized bed with bottom feed boilers. The operating results after renovation indicated that the unburned carbon in the fly ash has been dramatically reduced, and the boiler efficiency has been increased by approximately 20 percent. The successful renovation provided a feasible method to retrofit some boilers with lower heights and burning low-grade coals.
