600MW超临界CFB机组低负荷运行技术研究

Research on Low-load Operation Technology of 600 MW Supercritical CFB Unit

中国自主研发的世界首台600 MW等级超临界CFB锅炉,在四川白马示范电站成功投运。600 MW CFB锅炉具有大范围的调峰能力,在四川电网火电低负荷率期间显示了普通煤粉炉不可比拟的优势。针对机组长期低负荷下出现的异常工况进行分析,并制定相应对策措施,取得了很好的效果,保证了机组安全稳定运行,为后续超临界CFB机组提供了借鉴。

The first 600 MW class supercritical CFB boiler in the world developed independently by China has been successful- ly put into operation in Baima of Sichuan. The 600 MW CFB boiler has a wide range of peak shaving ability, which shows the incomparable advantages over common pulverized coal fired boiler during low - load rate in Sichuan power grid. The abnormal condition occurred in lone - term low load is analyzed and the corresponding countermeasures with good effects are given, which ensures the safe and stable operation of the unit and provides a reference for the follow - up CFB supercritical unit.
