焦炭塔工作过程温度场仿真分析
Temperature Field Simulation of the Working Process of Coke Drum
摘要
Abstract
Using the ANSYS finite element analysis software simulated the temperature field of the coke dram's working process. The data of top and bottom field surveying temperature linear fitted along the highly direction acted as thermal analysis boundary conditions, as the boundary temperature is a composite function about time and height, dynamic thermal boundary problem during the coke - forming and water - cooling stages was solved. Element birth and death technology was used for simulating the coke -forming process. Analysis showed that coke dram's temperature rises steadily during preheat and steam -cooling stages. In coke - forming stage, mixed - phase interface gradually rise up. When the dram wall contact with the interface its temperature will rising dramatically. Temperature change rate is high and the trend of thermal gradient variation is complex during water - cooling stage.关键词
