中文摘要 | 煉焦製程主要為泄製高爐使用之焦炭,除顧及產量及品質外,能源之點理化及環境污染之控制亦時常左右煉焦場之操作。煉焦製程基本上為一個龐大的燃燒系統,能掌握此系統即能同時克服前面之問題。煉焦完成之判定為此系統中非常重要的一步驟,如格準確地預測焦化時間為本文之目的。 由實驗結果大致可了解在昇騰管彎管之測溫最能代表製程之程序。同時由數據之整理,總煉焦時間可由因子回歸式及焦化指數(CI)法給予有效之預測。而後者比前者更簡單而實用。 |
英文摘要 | The requirement in standards for coke qualities has became more and more stringent, especially in modern blast furnace with high PCI ratio. On the other hand, energy consumption and environmental pollution must be minimized form view points of management of coke oven. In this situation, and efficient combustion control system was needed. Measuring the coking end point was an important process in this system. Therefore, how to set up an accuracy predicting model was the object of this study. The results showed that temperature measured at the throat of ascending pipe could be useful for accurately determining the coking end time. And total coking time could be also obtained both by a multi-variables regression equation and by Coking Index (CI) method. The latter is simpler and more practical than the former in on-site applications. |
