提高背压式汽轮机运行经济性的结构改进

Structural Modifications for Improving Operation Economy of Back Pressure Steam Turbines

针对背压式汽轮机补给水加热耗汽量大及热负荷偏低时经济效益差的主要缺点,提出了研制开发可调自回热背压式汽轮机及在热负荷不稳定的场合增设多功能小容量凝汽器等两项结构改进措施的建议.

Considering that back pressure turbines of small capacity have the disadvantages of requiring rather much steam for heating up make-up water and poor thermal efficiency at low loads, two structural improvements are proposed which consist of developing auto-adjustible regenerative back pressure turbines and the addition of mini-capacity condensers.
