摘要

针对湖北襄樊发电有限责任公司 4× 30 0MW机组锅炉粗粉分离器效率低、循环倍率高等问题

提出了将原轴向I型粗粉分离器改为串联双轴型的改造方案。改造后

粗粉分离器效率提高了 15 %以上

飞灰可燃物由 5 .5 %下降到 2 .9%

节能效果显著。

Abstract

In view of low efficiency and high circulating ratio problems of classifier for boilers of 4×300MW units in Xiangfang Power Generation Co Ltd

Hubei Province

a retrofitting scheme of changing original single shaft classifier to series double shaft one has been put forward. After retrofitting

the efficiency of said classifier has enhanced above 15%

combustible in fly ash decreased from 5.5% to 2.9%

having obvious effectiveness.
