摘要
针对均压箱压力对汽轮机热经济性的影响,通过计算分析了汽轮机轴封系统及抽汽系统的变化对汽轮机背压的影响。依据某电厂在实际运行及调试中的数据,计算出汽轮机经济性较好的均压箱压力和相应的汽轮机背压。
To study the effects of surge tank pressure on heat economy of steam turbines, an analysis was carried out to the influence of variation of both the turbine gland seal system and steam extraction system on back pressure of the steam turbine by calculation. Ideal surge tank pressure and corresponding turbine back pressure were calculated based on commissioning and operation data of an actual power plant, when good economic efficiency was obtained by the unit.
