摘　　要：针对K型合成氨厂工艺流程,借鉴低温变换反应器还原系统的工艺思路,充分利用现有设备,对高温变换炉升温流程进行改造,将低温变换还原系统与高温变换炉工艺管线相连接,实现高温变换炉单独升温,节省开工时间25h。This essay is concerned with the improvement of technological process in the Kellogg-type ammonia plant. Taking the idea of the reduction system of the low temperature shift reactor for reference, we aimed at reforming the heating process of the high-temperature shift furnace based on the original system. By connecting the low temperature shift reduction system to the process pipeline of the high-temperature shift furnace, we enable the furnace to heat up independently, saving the commissioning time by 25 hours.
