After research on a 2000t/h subcritical forced-circulation balanced v entilation were applied boiler and the structure and operation of its auxiliary system builds up this heat transfer model of a superheater's pipe wall and analy ze the effect of primary factors on the overtemperature of the pipe wall. Fault tree structure was used to uncover the multiplayer logic between the overtempera ture of the superheater's pipe wall and the faults. 相似文献

Nowadays, the scale of data normally stored in a database collected by Data Acquisition System (DAS) or Distributed Control
System (DCS) in a power plant is becoming larger and larger. However there are abundant valuable knowledge hidden behind them.
It will be beyond people's capacity to analyze and understand these data stored in such a scale database. Fortunately data-mining
techniques are arising at the historic moment. In this paper, we explain the basic concept and general knowledge of data-mining;
analyze the characteristics and research method of data-mining; give some typical applications of data-mining system based
on power plant real-time database on intranct.
