摘要

介绍了300MW循环流化床锅炉外置式换热器在运行中出现的问题

如进料锥形阀卡涩、锥形阀阀杆磨损、空室或一室内流化风量低、内部砌筑材料脱落、受热面爆管等

对此提出了相应的处理措施。实践证明

采取这些措施后

上述问题均得到较大的改善或解决。

Abstract

Problems occurred in operation of externally arranged heat exchanger for a 300 MW circulating fluidized bed(CFB)boiler

such as unsmooth jamming of material feeding conical valve

stem wornout of the conical valve

empty chamber or low flowrate of fluidizing wind in one chamber

fall-off of internal building materials

and tube-burst on the heating surface etc.

have been presented.For these

corresponding handling measures have been put forward.Practice shows that these measures are practical and feasible

having reference value for other similar type units.
