在第一實施例中，由於在推焦側及導焦側是位於煉焦爐150與外界空氣的交界處，所以推焦側及導焦側附近的加熱單元153的溫度會設定的較低，以保持煉焦爐150位於推焦側及導焦側附近的材料結構不會因為溫差過大而損壞。因此，在提供加熱單元153之溫度值之步驟110中，可僅提供從距離推焦側151算起最近的第四個加熱單元153的溫度值至距離導焦側152算起最近第四個之加熱單元153溫度值，亦即在靠近外界前三個加熱單元153的溫度不列入後續的計算範圍內，以測得較準確的結果。In the first embodiment, since the push focus side and the focus side are located at the boundary between the coke oven 150 and the outside air, the temperature of the heating unit 153 near the push focus side and the focus side is set lower, The material structure that keeps the coke oven 150 located near the push side and the focus side is not damaged by excessive temperature difference. Therefore, in the step 110 of providing the temperature value of the heating unit 153, only the temperature value of the nearest fourth heating unit 153 from the push-side side 151 may be provided to the nearest fourth from the focus side 152. The temperature value of the heating unit 153, that is, the temperature of the first three heating units 153 near the outside is not included in the subsequent calculation range, to obtain a more accurate result.

接著，進行判斷步驟130，判斷標準偏差值、溫度斜率差值、兩側平衡指標值以及凹凸平衡指標值是否分別在預設標準偏差範圍值、預設溫度斜率差範圍值、預設兩側平衡指標範圍值及預設凹凸平衡指標範圍值內，以提供判斷結果。Next, a determining step 130 is performed to determine whether the standard deviation value, the temperature slope difference value, the two-side balance index value, and the bump balance index value are respectively in a preset standard deviation range value, a preset temperature slope difference range value, and a preset side balance. The indicator range value and the preset bump balance indicator range value are provided to provide a judgment result.
前述的判斷結果中，若是所有經計算步驟所得數 值皆在預設範圍值內，則判斷此些加熱單元153的溫度分佈是屬於正常分佈；反之，若有一個或多個經計算步驟所得數值未在預設範圍值則為異常分佈，需要進行加熱單元153溫度的調整。Among the above judgment results, if all the calculation steps are obtained If the values are within the preset range value, it is determined that the temperature distribution of the heating units 153 is a normal distribution; otherwise, if one or more of the calculated steps are not within the preset range, the abnormal distribution is required.
