摘要
采用稳燃腔煤粉燃烧器并将三次风下移等技术对湖北青山热电厂410t/h锅炉燃烧器进行改造,成功地将该炉原设计燃用烟煤改燃为贫煤,并取得了改造后55%负荷可无油稳定运行,锅炉热效率达到90%的良好效果。
The burners of410t/h boiler in Hubei Qingshan Power Plant were retrofitted by using the pulverized coal burners with stabilized-firing cavity and moving tertiary air downward etc.technologies,thus the boiler was successfully converted from originally designed burning bituminous to burning lean coal,the boiler could operate stably at55%load without oil-firing aid and the thermal efficiency of boiler reached90%.
