600MW超临界直流炉滑参数停机下烧仓与汽温控制

Control of Burning Bin and Steam Temperature of 600MW Super-critical Once-through Boiler During Sliding Parameter Shutdown

以彬长电厂600 MW超临界直流炉兼顾烧仓的滑参数停机为例,分析了超临界直流炉滑参数停机下影响主汽温度波动的主要原因,提出滑参数停机过程中汽温控制的要点及如何保证滑停过程中烧仓与汽温同步下滑的控制方法。

Taking the sliding parameter shutdown with burning bin of 600MW super-critical once-through boiler of Binchang Power Plant as example, the main reasons are analyzed that influencing the steam temperature variation during the process of sliding parameter shutdown. Essential concerning steam temperature control is given during the process of sliding parameter shutdown, and the methods of controlling the steam temperature and burning bin synchronous decline are also explained.
