低温膨胀机效率对液体空分的能耗影响分析

摘要

The efficiency of booster side of cryogenic turbine is lower than design, the pressure to turbine inlet is lower;the turbine side efficiency is lower, the flow is higher. The consequence will be the power consumption of the plant is higher.%低温膨胀机增压端效率低导致增压流体压力偏低，影响膨胀机膨胀入口压力；膨胀端效率低直接影响膨胀机产冷，导致流量增加，空分能耗偏高。
