Abstract: There was the problem of pulverized coal deposition in the primary air pipe of dual inlet and outlet ball mill of #7 boiler in Zouxian Power Plant, and the primary air inlet temperature was on low side. The present situation of the boiler was examined concern with design, installation, coal quality and other factors. Thus the causes of the coal deposition and lower temperature mentioned above were analyzed, and some preventive measures as well as suggestions were proposed in this article.
