摘要
对增压锅炉汽包在瞬态状态下所受到的工质的内压应力和热应力进行了分析,得出了增压锅炉汽包在瞬态状态下所受到内压应力和热应力随时间变化的规律以及汽包的应力集中部位,为增压锅炉汽包在瞬态工况下的安全运行,最优启动以及变负荷方案提供了理论依据。
This paper pressurization boiler drum in transient state are working within the compressive stress and thermal stress is analysed and the pressurized boiler drum in transient state by compressive stress and thermal stress in changing with time and the stress concentration of the drum for pressurization boiler drum, transient conditions in the safe operation, the optimal variable load startup and provides theoretical basis for solutions.
