中置式与后置式副产蒸汽氨合成塔的研究

A Study of By-product Steam Ammonia-synthesis-tower with Mid-set or After-set Type Boiler

带中置锅炉的氨合成塔和带后置式锅炉的氨合成塔，在结构和节能方面有许多异同之处．本文经过计算，定量地对这两种塔进行比较．

There are many common and different aspects of structure or energy-saving in ammonia-synthesis-tower with mid-set boiler or after-set boiler. This two kinds of ammonia-synthesis-tower were compared by computing according as their structures and energy-saving properties.
