| 摘 要： | 锅炉给水泵作为空冷机组的重要辅助设备,对机组的安全和经济运行起着非常重要的作用。以国内某超超临界1 000 MW空冷机组为研究对象,用等效焓降法对汽动给水泵的经济性作了分析,结果表明,经济性较电动给水泵非常明显。并对给水泵汽轮机的运行模式作出了合理的评价。

| Abstract: | As an important component of air-cooled unit, the boiler feedwater pump plays a significant role in the safe and economic operation of power units. For uhra-supercritical 1 000 MW air-cooled unit, the economics of steam-driven feedwater pump is investigated based on the enthalpy drop method. The result indicated that the economics is more obvious than electric-driven feedwater pump. The operation mode of the feedwater pump steam turbine is assessed in a reasonable way. |
