摘　　要：马钢20000 m3/h制氧机运行多年来存在下塔精馏工况不稳定,易发生液悬,氧气产量达不到设计值,液氧泵出口压力低,氮压机易进入喘振区等问题,造成机组并网能力低,运行能耗高。详细分析了制氧机产能低的原因,介绍了提升产能所采取的措施,以及措施实施效果。Problems such as instability of the lower tower rectification, tendency of liquid suspension, oxygen production capacity short of designed value, lower pressure at the exit of liquid oxygen pump and nitrogen compressor entering the surge area existed in the 20000m3/h oxygen generator of Ma Steel for years, resulting in low capability of grid connection of the unit and high operation consumption of energy. The causes of the low capacity of the oxygen generator were analyzed in detail and the measures taken for enhancing production capacity and the result were introduced.
