【摘要】 国产引进型 30 0MW汽轮机组冷端系统性能不良的问题具有普遍性 ,严重影响热力设备的经济运行 ,不少发电厂试图以增加凝汽器冷却面积来改善机组冷端性能 ,但因无试验数据 ,难以形成统一意见。对此 ,通过计算分析和现场试验数据论证后认为 ,国产引进型 30 0MW汽轮机组凝汽器的设计冷却面积宜在 (16 0 0 0～ 170 0 0 )m2 范围。更多还原

【Abstract】 The bad performance problem of cold end system concerning home-made imported type 300 MW steam turbine units has universality, seriously affecting economic operation of the thermal power equipments, but it is difficult to reach a common understanding for lack of test data. A lot of thermal power plants are trying to improve the unit’s cold end performance by increasing cooling surface of its condenser, it is considered after calculation analysis and verification of field test data that the designed cooling surface of home-made 300 MW steam turbine units is suitable to keep in a range of (16 000～17 000)m~2.更多还原
