摘　　要：下花园发电厂1号锅炉的飞灰含碳量在一段时期内较往常有较大幅度增长,平均为5.3%,最高达到8.09%,运行经济性降低。通过喷燃器结构及布置形式的改造,使煤粉在炉内得以充分燃烧。飞灰含碳量降低,使得发电成本随之降低,给企业和社会带来了很大的经济效益。Carbon in fly ash of boiler 1 in Xiahuayuan Power Plant rises by a bigger margin in a certain period than usual in the past,average value is 5.3%, maximum value is 8.09%,Which reduces the operation economy. The modification was made to burner structure and arrangement which makes pulverized coal to be burned fully. The reduced carbon in fly ash lowers the generating cost and brings the economic benefit for electric power enterprise and the society.

关 键 词：电站锅炉 飞灰含碳量 燃烧器改造 经济效益
