600MW超、亚临界机组收益及临界标准煤价探讨

Exploration on the Yield and Critical Standard Coal Price for 600MW Super & Subcritical Units

指出常用经济比较法回收年限法的缺点，介绍了年收益法分析并引入600MW超、亚临界机组“临界煤价”之概念，认为我国相当长的时间内建设600MW超临界机组的燃煤电厂不够经济。

This paper points out the deficiency aboutthe common economic comparison method (payoutperiod method). Using the annual yield method for an-alyzing and intruducing the concept of 'critical coalprice' for 600MW super & subcritical units.
