摘要:
在实际运行中,大型机组双压凝汽器普遍存在着高、低压侧压差明显偏离设计值的问题.现从机组汽缸布置等方面分析了问题的成因,并通过对超超临界1 000MW机组双压凝汽器的计算分析,揭示了高、低压凝汽器的凝结负荷偏差对其压差及加权平均压力的影响.结果显示,低压侧凝结负荷增大,虽然使高、低压侧的压差小于设计值,但是对等效压力的影响很小,对机组热力性能不产生明显影响.
Abstract:
In prac tica l opera tion, the problem that the pressure d iffe rence be tw een h igh and low pressures condensers obviously derivates from the design va lue is qu ite un ive rsal for dua-l pressure condensers of large steam turbines. Th is paper ana ly zes causes o f the problem in term s o f the layout of cy linder un its, and through the calcu lation and ana ly sis o f the 1 000MW ultra-supe rcr itica l units w ith dua-l pressu re condense r, rev ea ls the im pact tha t the condensing load dev iation of high and low pressure condensers has upon the pressu re d ifference as w ell as the w e ighted av erage o f pressure. The results of the research show that although the increase o f condensing load o f the low pressure side m akes pressure d ifference low er than the design va lue, ye t it has little impact upon the equ iva lent pressure, and has no obv ious impact upon the rm al pe rfo rm ance of the un it.
