氨合成塔内件是小氮肥生产中最关键的设备。正确选择性能优越的合成塔内件之后，安装问题就摆到了面前。安装质量的好坏，不仅制约内件性能的发挥，而且影响全厂生产的稳定运行。本文以内冷绝热复合式氨合成塔内件的安装，结合部分使用厂家出现的问题，进行分析和探讨。1安装前 Ammonia synthesis reactor internals is the production of small nitrogen fertilizer the most critical equipment. Correct choice of superior performance after the synthesis of the inner parts, the installation problems on the front. The quality of the installation is good or bad, not only restricting the performance of internals, but also affect the stable operation of the whole plant. In this paper, the inner heat-insulated composite ammonia synthesis tower inner parts of the installation, combined with the use of some of the problems manufacturers, analysis and discussion. 1 before installation
