| 摘 要： | 在各种不同的化工产品的生产过程中,各反应过程都是在高于或低于环境温度下进行,但其最终温度都会恢复至环境温度.将产品所蓄的热量或冷量充分的加以回收是生产过程中节能的重要手段.本文给出了怎样根据不同的温度段画出各物流的热（火用）图,并给出了两种以上物流的热（火用）图复合的方法、步骤,还给出了怎样根据复合后的热（火用）图组织生产和热回收系统,以达到最大的节能效果.从文中的实例可以看出可提高余热利用率14.4%.

| Abstract: | Process of many chemical manufacture is carried out under temperature higher or lower than environment temperature, but it will change to environment temperature in the end. Recovery of energy contained in the manufacture is a important means for saving energy. This article provides method of how to make heat-exergy chart based on different temperature, and also provides complex steps of two or more kinds of matter stream. Moreover ways of how to form production system according to heat-exergy chart to save maximum energy are mentioned. From the instance it can been seen that rate of utilizing waste-heat is increased by 14.4 percent. |
