摘要
本文根据目前大量已投运二次再热机组运行经验,结合某660MW项目高效一次再热和二次再热不同的高效超超临界参数,结合对应的汽机热平衡图参数,通过对THA、80%THA、60%THA三个运行负荷进行了相关的机组经济性参数的计算和对比,通过分析提出了在选择一次再热或二次再热参数上的一些建议和结论。
This paper based on the operation experience of a large number of secondary reheat units that have been put into operation,combined with different efficient ultra-supercritical parameters of efficient primary reheat and secondary reheat of a 660MW project,combined with the corresponding steam turbine heat balance diagram parameters,Through THA,80%THA,60%THA three operating loads of the relevant unit economic parameters were calculated and compared,through the analysis of the selection of primary reheat or secondary reheat parameters on some suggestions and conclusions.
