华电潍坊发电有限公司二期#3锅炉投产后,飞灰可燃物指标一直偏高,为有效降低飞灰可燃物,提高机组经济性,采取了改变配风方式、保证合适的氧量、保证适当的煤粉细度等方法,使#3机组的飞灰可燃物指标有了明显的改进。

After the boiler No.3 of Huadian Weifang Power Generation Corporation Limited project phase II was put into operation,its index of combustible matters in fly ash are always higher.In order to effectively reduce the combustible matter in fly ash and raise unit economical efficiency,some measures,such as to improve the air distribution mode,to ensure the appropriate oxygen content and advisable fineness of pulverized coal,were adopted,and the index of combustible matter in fly ash of unit No.3 was improved obviously.
