随着区域供热需要,超临界技术在300 MW级供热机组中逐渐得到了推广,在节能优化设计方面做了很多尝试,同时也给运行调试带来了挑战。基于某2×350 MW电厂,论述350 MW超临界供热机组的特点,分析该型机组的调试关键技术,提出调试中显现问题的解决方案。所论述的一系列调试关键技术可供同类机组调试参考。

ABSTRACT： Due to the increasing demand of regional heat supply, supercritical technology has been gradually applied and promoted in 300 MW cogeneration units. Technology optimizations have been carried out on the aspect of energy saving, while challenges have also been presented to unit operation and commissioning. In a 2 × 350 MW power plant, the features of 350 MW supercritical cogeneration unit are introduced, and the key technology of its commissioning is analyzed to suggest a solution for the problenas in commissioning. The proposed commissioning technologies could be references for similar units＇ commissioning.
