    Abstract: 燃燒界限是處理、運送及儲存可燃蒸氣及氣體的重要安全指標之一。因此,許多學者對其進行量測實驗或建置預測模式。在本研究中針對可燃氣體混合及可燃氣體於純氧中的情況進行探討,欲建置可燃氣體混合物之燃燒上限預測模式及推估可燃氣體於純氧中的燃燒界限。
    可燃氣體混合物之燃燒上限研究部分基於氣體間搶氧能力的關係推導出的預測模式,經由文獻中的甲烷-丙烷、甲烷-乙烯、甲烷-乙炔、甲烷-正丁烷及丙烷-異丁烷實驗數據進行迴歸分析,結果顯示推導出的預測模式適用於上述五種組合的燃燒上限。
    可燃氣體於純氧中的燃燒界限研究部分由質能平衡觀點出發並利用可燃氣體於空氣下的絕熱火焰溫度反推可燃氣體於純氧中的燃燒界限,其預測值與實驗數據值進行比較,結果顯示其整體預測誤差皆在可接受範圍內,所以此預測模式可作為工業上一個快速推估純氧狀態下之燃燒界限的方法。

    In processing, transporting and storing combustible liquids and gases, people rank the flammability limits as a crucial safety index. Therefore, many researchers carry out experiments on or set up prediction models for them. In this research, we want to investigate the mixing of combustible gases and combustible gases of pure oxygen. Theoretical models to predict the upper flammability limits of mixtures that with two organic combustible gases and estimate the flammability limit in pure oxygen of combustible gases.
    Mixture of combustible gases based on the ability to grab oxygen relationship, developed a model to predict the upper flammability limits of mixtures, through the literature experimental data of methane - propane, methane - ethylene, methane - acetylene, methane - Isobutane and propane - n-butane to regression analysis showed that the prediction flammability limit model is apply to the five combinations.
    From the viewpoint of mass-energy balance and use adiabatic flame temperature of combustible gas of air to estimate flammability limit of pure oxygen, the results shown that the predicted value is close to experimental data, so this prediction model can be as a quick state to estimate the flammability limit of pure oxygen in Industry.
