摘　　要：随着燃油温度的上升,不可避免地会出现热氧化结焦,如何对其进行抑制非常重要。通过对溶解氧含量对热氧化结焦影响的国内外实验进行归纳分析,发现当燃油中溶解氧完全消耗时,降低溶解氧含量可有效抑制燃油结焦,但要考虑实际过程中,若质量流速较大导致溶解氧仅部分消耗时,结果可能存在的差异。然后针对去除燃油中溶解氧的方法及一些燃油除氧系统进行介绍。With the rise of the fuel temperature, thermal oxidation coking appears inevitably, so it is very important to suppress this phenomena. The effect of dissolved oxygen content on thermal oxidation coking is summarized and it is found that reduction of the dissolved oxygen content can definitely inhibit the fuel coking after the dissolved oxygen is completely consumed in the fuel. However, considering the actual process, the conclusion may differ when the higher mass flow rate leads to the partial consumption of dissolved oxygen. Finally, a brief introduction to the removal of dissolved oxygen in fuel and some fuel oxygen system was proposed.
