| Abstract: | In view of troublesome problems influencing upon the safety of 125MW units with hot air for sending pulverized coal and allocation of the primary air,such as fire-carrying in the primary jet orifice,and slagging on the water-wall in zone of burners etc,occurred after enhancement of volatile and heat value in the coal. Aim at these problems,there are some solutions have been summarized in the paper and we have analyzed the merits and drawbacks of the various solutions combined with the specific examples. When the problem such as fire-carrying in the primary jet orifice occurred in the 125MW units,we can draw lessons from these solutions. |
