1) low the back of pressure
降低背压
2) lower back pressure
低背压
1.
However,larger exhaust loss in the lower back pressure is increased,and the heat rate mean value in the lower and higher back pressure is higher than that in the single back pressure turbine.
通过计算,得出凝汽器冷却水温度在分界温度值以上,采用双背压凝汽器可以提高机组的热经济性;同时由于低背压的影响,该侧的排汽损失增大,使双背压汽轮机高背压与低背压的平均值对应的热耗率要高于单背压汽轮机的热耗率,使机组的热经济性有所下降。
3) stepdown
降压的降低
5) the low department of the electrolysis slot presses to decline
炉低压降
6) low pressure drop
低压降
