摘　　要：加料煤在焦化过程中需先经干燥阶段,且热量由炭化室炉墙逐步向中心移动,即所谓“成层结焦”。本文应用移动边界理论,详细地讨论了炭化室内水分变化情况,并与焦化过程离散状态空间模型结合,进行了计算机仿真,并在重钢焦化厂进行了工业测试。结果表明模型满足工业控制要求。In the cokemaking process, the charging coal must be desiccated first, and the heat must transfer gradually from the oven wall to the center. In this paper, mathematical description of boiling, condensation and convection of steam in the coke oven has been in detail discussed with the 'boundary-moving' theory. By comparison the simulation results with the industrial test results, it can be seen that this model meet the requirement of industrial process control.
