本研究主要是分析圓柱形旋轉式加熱爐的暫態行為，利用時域之有限差分法(Finite difference time domain method)為分析基礎，並使用自行開發的SimLAB 2000模擬程式，探討不同旋轉爐變數的作用之下，對於在爐內溫度分布的影響程度，進而找出適合的變數值組合。本研究選出4個加熱爐的重要變數，分別為爐體轉數、輸入功率、爐長、爐床填充率，將各個變數選出數個數值代入，觀察爐床溫度隨軸向位置變化的趨勢，最後配合灰色系統理論(Grey systemtheory)的灰關聯分析(Grey relational analysis)，找出各個變數對爐床溫度影響的程度大小。由灰關聯分析結果顯示，影響爐床溫度最大的變數為輸入的功率，影響最小的為爐床填充率，而爐體長度的影響程度會比爐體轉數大。選定輸入功率來進行爐床出口溫度的模糊控制，在SimLAB 2000加入模糊控制器，控制後的爐床出口溫度符合設定的需求。 The purpose of this thesis is to study the transient thermal behaviorof rotary kiln. Base on the Finite Difference Time Domain Method, weuse the SimLAB 2000 simulator developed by ourself to study theinfluence of control parameters on the temperature field of bed in thekiln. We choose four important parameter rotary speed, input power,kiln length, and the fill rate of bed. The temperature distribution iscalculated by several selected values of parameters. At last, we useRelational Analysis of Grey System Theory to find the influentialintensity of individual parameter to bed temperature field. From thesimulation results, the most important parameter is input power, theless effect is the bed fill rate, and the influence of kiln length islarger than rotary speed. We use the fuzzy controller in SimLAB 2000,which consists of one parameter that is input power to control thematerial temperature. The temperature response satisfies ourobjectives.
