马钢40000Nm^3/h制氧机组空气流量控制方案的改进

Improvement of the Air Flowrate Control Scheme for Masteel's 40000Nm^3 Oxygen Making Machine

通过对马钢40000Nm3/h制氧机组主空分系统工况波动原因的分析,改进了空气流量控制方案,使进冷箱空气量保持平稳,基本无波动,促证了整个空分系统工况的正常,从而使40000Nm3/h制氧机组稳定运行。

Through analysis of the causes of operation fluctuation in the main air separation system of Masteel＇s 40,000Nm^3/h oxygen making unit, the air flowrate control scheme is improved, to make the air quantity in the cold box keeps stable with little fluctuation and ensure normal operation of the whole air separation system, leading to the stable operation the 40000Nm^3/h oxygen making unit.
