摘要

本研究主要是以氣態揮發性有機污染物甲苯為標的，採用直燃式焚化爐並搭配熱能回收設備，在燃燒破壞效率方面以焚化溫度及焚化時間作為變數，在能源效率方面則以熱傳面積作為主要變數，探討甲苯燃燒破壞效率及能源效率之關連性，在同時兼顧兩者的狀況下，建議較佳之操作條件，並於實場中進行驗證。
實場中以焚化溫度710℃、720℃及730℃，焚化時間0.5s下，進行甲苯採樣分析，其甲苯燃燒破壞效率分別為94.2%、98.6%及99.3%，此時能源回收效率分別為47.6%、48.0%及48.4%，此時，甲苯燃燒焚化效率與能源回收效率之線性關係為0.8434，當焚化溫度越高，則燃燒焚化效率與能源回收效率兩者關聯性則越
低，若在定溫狀態下，因改變焚化時間而增加之燃燒焚化效率或改變熱傳面積所增加之能源回收效率，並不影響兩者之關連性，顯示同時影響兩者的參數為焚化溫度，依據本研究結果，焚化溫度在710℃~730℃，且熱傳面積介於575m2可視為最佳操作條件。

This study is based on gaseous volatile organic compound in toluene as the subject, using the direct combustion with heat recovery equipment, the combustion destruction efficiency of incineration temperature and incineration time as a variable and the energy efficiency of heating surface as the main variable to explore the toluene relevance of the combustion of the destruction and energy efficiencies. Taking into account both of the situation at the same time, it is recommended that the better operating conditions and verify the experiment.
In the experiment, to assay the sampling of toluene, the incineration temperature are 710℃, 720℃ and 730℃, and incineration time is 0.5s, the toluene destruction efficiency are 94.2%, 98.6% and 99.3%, at the mean time, the energy recycling efficiency are 47.7%, 48.0% and 48.4%, mean while, the toluene destruction efficiency and linearity of relations the energy recycling efficiency is 0.8434, when the incineration temperature is higher, the related of the destruction efficiency and energy recycling efficiency are lower, if it is in the same temperature, changing the incineration time and increase the incineration efficiency or changing the heating surface to increase the recycling efficiency of energy do not affect both of the two correlation, it shows that the incineration affects the two parameter.
According to the result of the studying, the best operation condition, the incineration temperature is between 710℃~730℃, also heating surface is about 575m2.
