摘要
从生产操作和闭环控制的角度,提出可知裕量应当由工艺条件变化裕量(稳态)、设备老化裕量(稳态)和控制裕量(动态)等三个部分构成,并将这一概念应用于换热器操作与设计分析中。在换热器工艺设计中考虑控制裕量后,换热器操作不仅能够满足换热工艺要求,而且可以实现良好的控制(操作)性能。
In the light of process operation and closed loop control, it is proposed that knowable overdesign includes three parts: process condition change overdesign (steady state), equipment aging (steady state) and the control overdesign (dynamic state). This conception has been applied in the heat exchanger operation and design analysis. After control overdesign is included in the heat exchanger process design, not only the requirement of heat transfer process has been met, but also the excellent control performance realized.
