影响600MWe等级机组供电煤耗的因素

Influence Factors on Net Coal Consumption Rate of 600MWe Units

我国投运的600MWe亚临界参数以上等级机组近350台,占火电机组装机容量的37%。除了超超临界机组的供电煤耗比较接近设计值以外,其它机组距离设计值均有10gce/kWh供电煤耗之差。影响600MWe等级燃煤机组供电煤耗因素很多,有设计、制造因素,也有管理上的因素,深入分析这些因素对提高机组的经济性有一定借鉴意义。

There are about 350 units of 600MWe above subcritical parameter in operation in our country,which is 37% of total installed capacity of whole thermal power units.Only the net coal consumption rate of ultra-critical units is close to the designed value,the others are all less than the designed value by about 10gce/kWh.There are many factors influencing on the net coal consumption rate of 600MWe units,which may be caused by design and manufacturing,and also by management.Analyzing these factors in depth could...
