亚临界300 MW机组热再抽汽的本体可靠性特性的影响研究

Research on the Reliability of Thermal Re-extraction Steam of Subcritical 300 MW Unit

根据亚临界300 MW机组的结构和强度等设计特点,在机组不进行改造的前提下,提出以下降负荷方案。不同压力的供热需求,和机组负荷相适应,对应采用不同的应对措施来满足,进行不同压力及负荷下热再抽汽特性的计算对比分析,以期为同类型机组抽汽提供参考依据。

According to the design features of the subcritical 300 MW unit’s structure and strength,the load reduction plan is proposed without the unit being modified.The heating demand of different pressures is adapted to the load of the unit,and different countermeasures are adopted accordingly,and the pressure,load,and thermal re-extraction characteristics are calculated and compared to provide a reference for extraction of the same type of unit.
