高效超超临界机组再热热段温度选型

摘要

This article mainly researches hot reheat steam temperature selection of high efficiency ultra critical power plant. The correlative pipe material SA335-P92 and the high efficiency ultra critical boiler operation is analyzed. The conclusion is that it's reliable to increase the hot reheat steam temperature to 620℃and the risk could be eluded.%本文主要研究高效超超临界机组再热热段温度选择，通过对相关管道材质SA335-P92的研究，以及对超超临界机组锅炉再热器出口运行温度控制的分析，认为提高再热蒸汽温度到620益（汽机入口）是可行的，提供温度后所带来的风险可以合理规避。
