Abstract

Abstract: 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.

Key words: combustible matters in fly ash, air distribution mode, oxygen content, fineness of pulverized coal
